Thanks for letting me visit. It was great seeing the shop and talking about engines and my favorite topics - piston rings and motor oil!
@themotoroilgeek I was a fan of your Dad in racing. He was the king of doing a lot with so little. He also raised a great son. I was and Automotive tech for over 50 years and a race fan and a short track racing engine builder for most of that time. I love listening to people who know their job and back it up with test results and technical skill. You seem to be so passionate and not just a career. Not many of people like you around any longer. You also always seem to be happy with your life. That is a bonus!
I believe that you were at Gibbs when Toyota started in Nascar. The Camshaft failures they had seem to have had was a huge problem and it appeared that the Driven motor oils seem to have helped. That says a lot.
Thank goodness we have roller lifters in NASCAR now. Keep up the passion and intelligence as it makes you a rare person these days.
Thanks for going out to Utah and meeting with Dave and the crew while you were there. And Lake you do a great job making tribology easy for us to understand and all of the Information gained from Science Sir. I'm scared thinking about getting my 2005 6.0l back on the road, it has been sitting for 11 months due to me having a fall. But I need to get going again.
With the cost of new cars and maintenance through the life of the vehicle, the cost of maintenance and oil changes is diddly squat compared to having a new engine built. Same thing applies to transmissions and brake systems. Maintenance and fluid changes are going to save you money hands down in the long run.
In the 2 years since I bought my brand new Toyota, I’ve done 4 oil changes in 8,500 miles because of the conditions I drive in. Short trips 6 days a week. If you pull the dipstick out and the oil is dark, it will be solid black when you pull the drain plug out. I don’t let my vehicles get to that point, so I will assume that I can get 300k miles on the original engine. ????
YT must be suppressing your channel because I’m all about your subject matter and you’ve never popped up on my home page. Thanks for the great video
"There are no secrets, there's just stuff I don't know."
That is the million dollar quote. Never lose your curiosity, be a life long learner; regardless of whether you dig ditches or launch space craft, stay curious and teachable.
We are naturally curious. As young kids, we ask all kinds of questions. Never discourage a curious kid from asking questions. Never tell a kid you ask too many questions.
I will used this a quote
Thanks and God bless you
There are plenty of secrets they try to keep you from learning.
A-men bro!
@@waitaminute-vw9hf ^this
I love how humble these guys are.. They can admit when they don't know something... intelligent
I swear i could listen to these guys all day. Most engineers built some pretty cool stuff but never got their hands dirty. These guys know their stuff
and you don't have Tinnitus? 🤔
Really good engineers do get our hands dirty, and the techs respect us because of it, just like we respect them.
Smart engineer is a lifelong teacher and a learner, always teaching the principles behind machine manufacturing and design, and learning about service and reliability from the techs
I appreciate you put yourself on camera and said "this is what I do, tell me if it's right or wrong, and why". And there were honestly a thing or two he asked you to adjust.
Some places would never let that see the light of day. However, it makes me respect your work more! If my engine builder isn't learning, their product isn't getting better
Well said!!
Yep. totally agree ! it's cool 😎 to see Them Learning too ! & then Putting that knowledge to the test to see if it actually pans out in the real world. Us Being the Flys on the Wall is incredible !
It’s a shame the manufacturers have stopped learning. Internal timing belts for example.
Thankfully the boomer mentality of "I already know everything" is fading out.
@@maxnovakovics2568 How about your mentality of lumping people into groups of perceived behaviors instead of thinking of people as individuals? Can that fade out too?
The insatiable hunger for knowledge is what makes/keeps these guys great. No ego, no shortcuts, just seeking the best way to construct a product. Awesome job.
Are you for real? The amount of ego stroking they were doing to each other took up so much of the video I gave up trying to find the part about motor oil.
@@ebaziukbecause it’s a real interaction they’re not really trying to play it up for the camera it’s just coming along
@@lamp7746 In editing they chose to leave that part in. They want the public to see this time wasting circle of jerks.
@@ebaziukis it fair to say your not a subscriber? I’m guessing it’s fair to say you’re a cliff note kinda guy vs a full documentary kinda guy! Nothing wrong with being a cliff note guy, just recognize the content ur watching b4 bashing them ! They were doing nothing more than a question and answer. Dave clearly had two or three ahah moments in this video where he realized they were doing something wrong, if he was trying to puff his chest out and inflate his ego he would have edited those moments out!
@@kenwillis8487 Right I'm not a subscriber I did a search for something and the headline advertised to answer that question... It felt like a bait and switch, I ran out of patience and time before they got past the circle jerk.
Who the hell ever thought I could sit through an oil video and be entertained by the subject. Thanks Geek.
40 plus years a mech and this video was mesmerising!
Lake Speed Jr has so much knowledge that I gladly watch anything he has to say
💯
He sucks
@@El_Peto
Too hard for you
Facts
and one of the few people that pronounces Porsche correctly.
I was a auto technician for 38 years and agree most engine failures and problems are due to lack of maintenance. Great talk by the way. Excellent
Absolutely yes. If all drivers/ customers would check their oil when they fuel up, we would sell more than half as many engines. What happened to the days of "full service" gas stations? They did this job for you.
"Full service" was too good to last , I still try to inform about it.
I was chastising a smart ass⚗ usician w/no oil showing on his dipstick!
" ..do you know what this means?" , I said.
He said, "yeah, it means I need a longer dipstick!"
@@aaronsmith5433 LOL!
Even a shitass fiat/chrysler?
Audi & BMW with their electrical problems and oil leaks?
Modern GM plastic rear main seals?
@@Soldier1287 You forgot no quality control fords...
I used oil analysis when I was an owner operator. The condition of the oil tells you so much about the condition of your engine. I never experienced a single catastrophic failure in millions and millions of miles of operation. Your oil tells you what is wrong well before any kind of failure and you can get it scheduled for repair in plenty of time. We used 1 micron oil filtration and sampled every 15000 miles on our MBE4000s and made engines everyone told me would die around 850,000 miles all run 1.5-2 million miles before rebuilding. We bought them around 550-600k miles and ran them as team trucks. Most reliable trucks I ever owned.
What kind of oil filter did you use? Even Cat filters only go to 2 microns.
Yep, I worked on aircraft for years and you run UOA on everything from engines to gearboxes and hydraulic systems. On my own car I send a sample every 5th oil change, which is around 20k miles as I like 4k intervals the best out of all the duration I tried (best balance between oil life vs the cost for my driving). For the $35 is costs to have tested, its way cheaper than letting a bearing spin or something like that.
@@arc00ta The CFM-56 engine that powers the KC-135R and commercial aircraft has an average time on the wing of 30,000 hours before a shop visit due to world-class bearings and strict UOA schedules.
I just got hooked up with a 4 pack oil test kit from Amsoil for like $120. They contract out the oil analysis to Polaris and write up a customer report too. This way I know what to expect. My truck runs 80WHP/100WTQ over stock at higher boost pressures. To keep it solid for the long run you got to put in the extra work. Plus, selling it later for top dollar goes I long way with receipts.
@@cdsmit27 Cat engineer at the filter plant told me that less than 2 microns starts to strip additives out of the oil, but this O/O seems to have made it work…
After over 35 years in the automotive service industry, with 10 years with Porsche and 25+ years in my own foreign car shop, I have lived by and preached that maintenance is the key to longevity. Mt automotive experiences and love came from my teenage years in the 60s when we built and dropped V8s into everything. Building hot rods, either for ourselves or others, is what kept us out of trouble. After that, I enlisted in the Navy and was designated an Engineman. That's where my diesel experience started. When I got out, Porsche was the only manufacturer that offered me a decent job. My career choice helped me become a millionaire. I'm "retired" now and this video was extremely interesting and memory-producing, thanks!
In regards to detergent fuels, Costco is one of the only places that carries Tier 1 detergent fuel.
Thanks for that Costco info.

We need a 4 - 5 - 6 hour long special with all you guys.
@Alex-nb6rm Alright, then don't watch or listen. Since you clearly don't care about education or the right to repair.

@@dans_Learning_Curve Yeah, I wasn't planning to respond to him any more.
If they don't change after 2 responses they're a waste of time.
This is probably my favorite video so far from Dave's auto center. The conversation with Lake speed Jr is fascinating to me. Now if we could get you guys and Gale banks in a video together. That would be the dream team.
You'd get a load of self-centered, entitled, box full of 💩💩💩 if you did that...
This was hands down, one of the best videos I have ever seen on RUclips
I was reading about a Peterbilt with a series 60 Detroit 425 HP engine. Almost zero engine wear at one million miles and only one oil change. Im a little familiar with this truck. It used Shell Rotella 15 W 40 conventional oil and a Gulf Coast O2 bypass filter. A mechanic didnt get the word to not dispose of the oil. Its misleading to say only 1 oil change in a million miles. The Gulf Coast bypass filter holds 3 gallons of oil. Thats 3 gallons of new Rotella every 10 K miles. Then you have the full flow filters changed every 50 K miles. Road King magazine article said that is equal to a full oil change every 40 K miles. I dont drain the oil in my 06 Pontiac but every 6 K miles I change the Australian Jackmaster Classic and add a new quart of synthetic oil. I drive mostly highway. I started in 1963 with a Frantz oil cleaner and Standard Delo 30W. In those days we changed the bypass filters more often and added more new makeup oil.
I did oil analysis all the time on my Freightliner. One time it picked up a lot of potassium which they use as road salt around here.
After looking around I discovered the shop left a turbo intake clamp loose, so it was sucking in road spray.
Without oil analysis I would have went all winter without knowing, leading to the engine getting dusted and worn out.
I add a banana to my crankcase oil for potassium
How do you go about getting an oil analysis? Mail a sample of used oil to a lab?
@@Will97675 I used the local Caterpillar Heavy Equipment dealer. Cat has their own lab. They sell prepaid sample bottles, fill it up, fill out the form. Then dropped off at the dealer. The lab emailed the results within four days.
Outstanding episode! Smart men listen to other smart men and guess what happens, we all benefit. What a great collab.
Appreciate the comment! That's the great thing about this community, we all come here to learn together👍
Question.
Why don't you vent the crankcase to atmospheric pressure? For instance, by loosening the oil cap or pulling the dip stick out a bit so it doesn't seal?
Less pressure on backside of cylinder, less crap through EGR.
@@lawrenceralph7481some people do have crankcase breathers that vent to the atmosphere (even tho they’re technically illegal). I used to have an oil catch can on my Camaro that condensed the oil vapors prior to the intake manifold but the valves still got coked up
It's a EPA thing. Bad for the environment. Starting in the late 60's. Regulation.
@@lawrenceralph7481 I do that after ever landing in my airplane. I pull the dipstick out and let the hot moisture escape. The camshaft is at the top of the engine so the oil drains off leaving the camshaft bare and exposed to rust. Also add expensive Camguard at every oil change.
Ugh I LOVE videos like this. Sharing the knowledge that 99.9% of people don't know and a very small percentage of us CRAVE! I just need definitive sources like this I can point people to when they question what I say about oil. Really awesome conversation and lessons. Thank you!
Appreciate you guys taking the time to sit down and record the session. Great insight to the nuts and bolts of what matters to keeping an engine going for the long run. Keep up the awesome content!
You bet!
It's amazing that Dave is so passionate about automotive maintenance & repair. Hope his boys keeps churning out more like grandpa!
Bringing Dave and Lake together is a dream come true. I had to re run this show a couple of times to let it sink in ( 66 year old retired railroad engineer ). Here in Australia I run BP premium 98 and diesel. Regular oil changes and filters. Yes I drive my vehicles
was a very good education and discussion!
by the way, did you run those insane freight trains across the country? i just saw a video about those.
@@TonyLasagna Yes Tony. Freight, Passenger and last 10 years hauling iron ore. EMD GE and even old Alcos. What an era.
@@brucekellett2269 awesome bruce! that’s what i was watching - the ore trains going to the port and it emptying onto the ship. also the savannah lander passenger train. man, i’d kill to hear your stories!
@@brucekellett2269 Bruce, is being a locomotive Engineer a stressful job? 🤔
I work with a guy that used to be an Engineer, now he's running production machinery.

Would valve your opinion.
Have you watched, "The Ghan" on SBS?
Expires in 1 month. Comment recorded 24/4/2024.
I'd be surprised if you can't see it on RUclips somewhere after then.
It follows the 17 hour train trip from Adelaide to Darwin. There's 6 episode of about 3 hours each.
Even if you're not that interested in trains, it's an interesting, while being a relaxing watch...the clickity clack of the train on the rails can make your eye lids heavy.
I think there's a similar one on the Indian Pacific, the 65 hour trip from Sydney to Perth. I don't think it's as intense in recording every minute of the trip, that the Ghan doco does.
What a GREAT video! I have 2 associate degrees in Auto Tech and 27yrs as a line mechanic, now retired. I learned so much from this. This video should be required viewing for all line techs and motor heads!! Thank you DAC.
What a fascinating discusion. I just changed the oil on my little Fiat Panda. According to the user manual I didn't need to do it for another 2,000 miles. After listening to these guys I am so pleased that I did it early. The old oil was so black and watery it clearly needed changing. Thanks guys for sharing this with us all.
I’ve worked on Panda’s many times, and have owned a few. In terms of the last few models, the 1.1 and 1.2 Fire engines are extremely durable, but I’d always do what you did and change the oil around 2k miles earlier. The MultiAir engine is fragile by comparison; not only do I recommend 6-8k max oil changes, but also baby them a little, they have issues that can easily catch people unaware and mechanical failures in the MultiAir can be terminal at very low mileages. The new FireFly isn’t as fragile as the MultiAir, but it can’t handle the mileage that the Fire engines can. You made the right decision for sure.
What an education! Thank you for taking the time and effort to video Lake's visit to your shop. Lake's knowledge is extremely important to getting better service out of our vehicles.
Glad you enjoyed it!
Oil analysis is something I learned about in Army Aviation over 25 years ago. All the numerous gear boxes, transmission and engine oils were sampled and sent off to the lab. Now I have engine oil analyzed annually and the transmission fluid checked every two years. It costs, but I want to know of problems early to either fix or trade before it gets to expensive. Too bad it's not offered by the dealers when you purchase their extended warranty.
That’s a service feature I’d pay for.
Absolutely, 100%, Bill. Think of an analysis as being akin to a FBC/CBC Blood test assessing YOUR health. It's as close to a window of what's going on inside as one can possibly get.
Like trade the vehicle and pass the problem to someone else? lol nice!
Retired mechanic...outstanding job making such a comfortable relaxed and informative video. One of my favorite videos I’ve seen . Damn fun watching
So much humility and respect between these guys, it's awesome!
As a DYI mechanic, I just learned a ton and it has changed my PM schedules on all 3 vehicles right now including a 2012 civic with 225k. Thanks Dave!
From what to what?
That is awesome!
@@simonshurety3870 I'm curious as well, I'm still doing mine every 5k
Have 170 on my '12 Civic, had 400 on my 07 Civic before a deer and then rust killed it. All I did was never miss an oil change. I got 380 out of the 07 Civic and it still got 43mpg if I chose to hypermile. Both have only seen Pen oil with natural gas base.
My '98 civic wih 380k kilometers has seen all types of oil. It has been eating 0.7L of oil / 1000km for the last 150k km. It doesn't get better nor worse. The oil has always been changed at 8 to 12k interval. I guess the oil consumption is now stable at 0.7L/1000km just because with such a high consumption it always run on almost fresh oil (due to frequent adding). 😂
I can listen to Lake anytime. Very smart man!!!
...the Albert Einstein of oil...
At 26.47 begins the most important (and infuriating) piece of vehicle information I have heard in at least a year. Thank you! What an awesome video.
This was an absolute GEM 💎 of a video !!
Thanks everyone who participated in making this 👍
I feel so priviledged to have been able to listen to this information for free
I feel like I got about 2 college Courses worth of Useful Information. for free!
You can tell Lake REALLY understands the Physics... When asked about "Ring Flutter" with the Gapless Second Ring... NO hesitation... "Not an issue, since there is always Positive pressure " ( in the supercharged Diesels )
if you dont watch total seals channel missing out on so much info. love how he touched on fuel being being the #1 killer for oil. Whenever Lake Speed talks, just know its going to be 💎💎
Thanks!
@themotoroilgeek Lake is like the E.F. Hutton of lubricants.
Agreed 💯
have been watching Lake's oil videos for a while now.. and for him to visit dave's shop is GOLD..
Man I've gotten myself humbled by watching this. Thank you for sharing your knowledge in such an understandable manner!
Thank you so much Dave for letting us watch these videos at 75 years old I have not stopped learning from the old school to the new school in Moore new school I still love to learn so keep up the great work I am an old Motorhead Gearhead dude from the past still looking into the future I really am thankful for what you're doing and I appreciate this guest that you have on this part of your interview so much to learn and there's even much more coming down the road thank you again for so much of what you do and what you offer may God continue to bless you and your family always. Amen
Same to you👍
When I was in the army over thirty years ago, we had oil analysis intervals for our truck fleet for the company, it was part of the pmcs system,....preventative maintenance and check system.
We still do that in the army but due to cost considerations mainly only on big pacer items: tanks , howitzers, helicopters, armored vehicles etc.
Dave and Lake! Two of my favorite people to listen to talk about engine stuff! Well done fellas!
I could watch these guys talk all day. I love this channel as I always learn something. Never stop learning.
Lubrication specialist + Dave and his boys = Amazing content!
Great collab! you all could lay information on us for hours! Wish we could get some more!
Glad you enjoyed it!
Thanks!
Excellent video. Thanks for sharing. I always change my oil 3 to 5k intervals. Interestingly that's when the GM computer on multiple LS motors also believes it should be. If you want to drive to 300k miles and beyond on your original engine, then change the oil!
07 5.3l 4,000 miles interval, is where is at.
I’m shocked how much time and money people spend trying to figure out how NOT to change their oil. Nobody has ever said, “dammit, I did too many oil changes on this car”.
300,000 on my 5.7 Hemi ram.
250,000 on 4.2 Ford F150
@@bobd9868 like I get its messy sometimes when windy and a pain, but.....30-40 bucks for even top end oil/filters is cheap compared to another car..
@@bobd9868 lol that’s so true! I’ve changed my oil more often than I’ve washed my car lately which is a bit weird but it doesn’t cause me grief.
This is an outstanding conversation among professionals. Everyone in the room is an artist !
I learned something very interesting in this video, I've been doing my oil change intervals WRONG, been pushing 7,500-10,000 miles because the oil jug stated that, I'll have to re-learn this, Good stuff in this video, Thanks to your guest Dave
I wish I could hit the like button multiple times. I always learn something from both of you but I also get confirmation on things I have been preaching for years. Thanks
You rock!
This is one of the most Piston Head videos I’ve seen in quite a while. LOL! I love it! Thank you all.
Glad you enjoyed it!
The most informative content on oil, gas, diesel fuel that I have ever heard. Lake Speed, Jr along with Dave's crew helped me to understand so much, thank you!
I always learn from watching this channel but I have never learned so much so quickly. Thanks so much for having this TedTalk with Lake Speed Jr.; he is riveting to listen to. Highly approve.
I’d love to see more in-depth discussion from Lake about how fuel additives helps prevent carbon on GDI engines and what he thinks of top tier gas
Another super video.
I enjoyed how it was filmed like we the viewers were included in an informal, but great informative discussion. I hope Lake comes by again.
We would love to have him at our shop again! What a wealth of wisdom he is. Thanks for watching.
Thank you for including us with you in this huge informative seminar. Love your information that you and your crew offer!
My old man did oil testing for MANY large engine oil companies back in the mid 70's and the stuff he would tell me about, engine oil, rings, pistons, wearing, etc, all that, sound JUST like this oil guy talking. So I guess my old (now 78 year old) man was correct after all these years and to think, he had no formal training, just learned about it through testing and deductive reasoning. It's nice to hear guys like this talk, you just learn SO much from them!
WOW. That is all I can say. I have NO formal training in mechanics but I understood just about all of that. I did not know most of it but understood it. I really wish some of my friends and family would watch this channel.
Wow, thanks!
Lake Speed Jr & Sr are both awesome
4:36 my face and Myles face currently looking the same
Thanks!
Ditto that !!!!
This was awesome!!! Please keep inviting pros like this to your shop to "talk shop". The knowledge he shared is incredible!! Thank you thank you thank you!!!
Two motorheads totally geeking out over cars. Absolute joy on camera.
Great video! As a fleet manager now oil representative i found this really rewarding. many of Lakes positions on lubricants I am in total agreement with and have been practicing for years. It is refreshing to hear it from someone beside me! I have seen Lakes videos before and this one was especially rewarding because he wasn't pitching a particular brand as much he was discussing the industry issues . I really like your channel Dave i ran my own shop and had many similar thoughts. Its unfortunate that until recently the homogenization of ground transport didn't encourage much thought
Thanks!
As a retired cotton topped tech and shop owner since I was 10 years old you never quit learning in automotive. Fascinating stuff. We also had at our disposal a lubrication specialist of many years. We could call Dave and he rarely needed to consult a computer. He had a memory beyond belief and a passion similar to Lake's. He retired about two years ago as I did which is too bad for our industry. Love automotive RUclips shows of which your on top. Tanning in Tucson.
I've been tracking oil for a fleet for years and endorse everything here. I would add a few lessons shared with our new techs (because they do not get taught this in the schools either) - first is to fight the owner desire to extend drain intervals unless backed by the science - second is to use the best oil you can afford - third is to think of oil as the engine garbage can and that it has to go.
Those last two are the important ones for longevity - an engine can have a blowby problem, or a micro coolant leak and still survive if the oil is changed frequently enough. It can be helped to the next overhaul interval instead of being run to the ground and out of service early.
When we added telematics and started tracking the oil pressure, we were also able to watch fuel dilution in progress. We would see fuel in oil (often high oil levels it was so bad), but diagnosis was hit or miss depending on the tech. Oil analysis was always an oil drain or sample too late though, but when we plotted pressure we could see the point about 2 weeks later where it finally dropped. We learned a few things - first the unit did not need to be killed from service immediately - significant to the operations team - and we could use that second week to anticipate the severity (bad injector vs bad blowby vs over regen) and take a few days to review the other data and target our diagnosis. Lots of bad DPFs were found plugged with coolant residues because of cracks in EGRs for example. That burnt coolant residue was also elevating potassium and those nodules were scoring the cylinders too. Oil analysis would track that too.
I used to say my job was paid for by the engines I saved. Oil analysis was essential to that capability. Lots of resistance from management - oil and filters are seen as optional, analysis costs money, analysis of results costs money, some times analysis is wrong and they don't undersrand the value of training through mistakes. But it does work.
do you have any thoughts to share on using break-in oil, specifically regarding a brand new diesel engine?
@@tattooedmillionair we trust the factory did the run-in, and put our normal oil in but change it at half the interval. We are putting 500,000km on an engine before we even consider replacing them and the premature failure rate is very low and Cummins has been great with us on that anyways (they know we have the data and their engineers work with us on campaigns).
Hey I am from Norway and just wanna say its soo nice too hear really good conversation and @dave`s auto center you are great
This is one of the most informative videos I've watched in a long, long time. It was 30 minutes well spent nerding out on oil.
Lake is really cool he definitely knows what's going on. Excellent show you guys have it, that's for sure. We'll deserved.
Thanks!
This was not only very entertaining to watch, but extremely educational as well. Thank you for sharing with us.
Saw Lake Speed Jr. at a seminar in Carlisle Pa. Whn he was with Gibbs. What he said about why it is bad to just add stuff to shelf oil made sense and stuck with me. Have listened to what he has had to say since.
I agree with your oil change recommendation 100%
I change mine every 5000km’s because my daily driver Infiniti SUV calls for every 10,000km’s intervals.
I also agree with Lake’s comment about Porsche owners not driving their cars, however that doesn’t apply to me, because I have 250,000 km’s on my 1985 Porsche. And the engine hasn’t been apart yet.
I actually sent Lake Speed Jr a question on the oil I’m using in my Porsche and he responded to me within hours. He’s a smart cookie.
Awesome video as usual Dave, thanks for sharing with us 👍👍
To anyone reading my comment let’s not forget about the miles vs kilometres. We are using kilometres in Canada
The former head engineer for Nissan suggests changing your oil every 2500 miles. He said that's when engine oil starts to break down and engine wear begins.
I always used the suggested drain interval of the oil manufacturer, at cut it short early, not the vehicle manufacturer's interval. The owners manual assumes we're using their OEM oil & filter AC Delco, Motorcraft etc.
@@donniev8181 maybe years ago with conventional oils, but today with the good quality synthetic oils that’s out there I don’t believe we need to change our oil every 2500miles. Plus most cars and trucks back in the day only had 4 or 5 quarts of conventional oil in them. These days car oil capacity is much more. So I believe it depends on the car and the amount of oil it takes plus if it’s conventional or synthetic oil that determines how often you need to change your oil. Plus the kind of driving and the climate you drive in would also play a role in the intervals you change the oil. However I’d still change it half way through the manufactures suggested intervals. My antique Porsche has a oil change every spring after it’s been stored for the winter, and that thing holds almost 9 quarts of synthetic. I change it because the car sits for so long not because it has a lot of miles on the oil. I’m not saying that everyone should do what I’m doing, I’m just giving my two cents on the topic.
Are you changing your oil that often?
And if you are I’m sure it will definitely do your car a lot of good in the long run. I just done the conversion for km’s to miles and 2500 miles is 4023 km’s so I think we are both on the same page👍
@andyjohnson6548 Yes, I just recently purchased a new 2024 Toyota Camry SE, so I've only done my 1000-mile break-in oil change. However, I'm going to change my oil regularly every 2500-3000 miles and my filter ever second oil change. Oil is cheap, and engines are expensive.
@@andyjohnson6548 oil is oil, I'm pretty sure the head engine builder for Nissan knows a thing or two about engine oil. Even Dave said his warranty stipulations include changing the oil every 3k miles.
This is the crossover we needed
I’m absolutely fascinated by this stuff. I can’t say there’s a time I’ve watched a DAC video and not learned something. Thank you for all you do!
This has beeen by far, besides diagnostic training, the best 20 minutes of information for anyone in this field or any oil lubricated industry. This video is an absolute GEM, which makes me a proud Daves Auto subscriber, and OilGeek as well......just priceless
That was so good to hear all that information, I change oil in my van and car every 5000 or sooner !! And always before going on long trips!! Love your channel❤
I have been watching lake speed junior on you tube for a while. He is one smart guy. Love it!
We agree!
Thanks!
I've met Lake before. This guy is the real deal, and it doesn't hurt that he's super nice.
We NEVER stop learning!! Awesome to see great minds sharing knowledge for the benefit of everyone! I will be sharing this video with many of my friends and customers. Maintenance costs less than repair!!
I could watch this stuff all night.
As an owner of an old 7.3 IDI I can confirm that even with an electric fuel system that’s air tight, new injectors and the IP timed right my IDI won’t run right without a quart of atf in the fuel. It’ll start weird, & have issues starting. I can also tell that if fuel is older it’ll take longer to start.
Here in the US we have crappy fuel quality. I got a bad batch of fuel at a fuel station one time, & later down the road 10 miles the truck stalled. Coasted into a gas station and found my fuel pump Pre-screen was plugged. Cleaned it out, bled the fuel and within 10 min I was running again.
Had the same thing happen on a 2 year old 6.7L Cummins after filling up at a Murphys USA. Ended up putting a Fass lift pump in instead of sticking with the stock pump/filters. Also still refuse to fill up at Murphys no matter how cheap their fuel costs. Time will tell how much damage was done to the injectors and CP3
@@andymike6575 , the station I got the bad fuel at wasn’t Murphy’s. I’ve always tried to stick to Murphy’s if a can. I’ve noticed better fuel quality from them on my personal stuff. It seems fuel quality rn is kinda spotty. I’ll get good fuel then another station it seems like trash. Then when I get fuel for the 7.3 I’ll smell it to make sure it’s the right stuff.
@@michaelbenoit248 yes fuel quality does seem to be spotty which is why adding fuel conditioner and better filtration is so important regardless of region or biodiesel content. Gasoline and diesel quality has also dramatically decreased overall over the last 20 years
@@andymike6575 , when Biden took office 4yrs ago I went to get fuel for my 7.3, & either I got a bad batch of fuel or the fuel quality was dramatically lower because the amount of power I had before and after the fill-up was -5hp. It’s gotten bad to where if I don’t add a quart of atf to the fuel my truck will start/run like trash.
I've done NDT for years and that crack is exactly in the direction you would expect to see one that comes from manufacturing process. MPI often called Magnaflux testing should have found this initially but that doesn't help the current owner. NDT is an amazing career that is used from pipelines to spacecraft, tight tolerance motor parts to giant pinion and drive gears. Great example of a inherent discontinuity. Love the channel.
Hopefully they see your comment.
Knowledge is power. Thank you for bringing in the experts. I change my oil every 5000 miles.
Your videos are great. If I am ever in Utah I would like to stop by .
That was great. Oil is cheap engines are expensive is what I was taught. Bought my first brand new truck in 1987 just out of high school, Ford Bronco with 302, first oil change at 1000k, 3000k after that. sold 10 years later with 180k still ran like new and never touched engine other external components. All Toyotas now and change oil 3k first/new and then every 5k. Brother in law says his new Volvo only needs every 10k so cheaper maintenance. We'll see how long it lasts.
Sounds like Scotty Kilmer. Keep the good work up and long live your machines.
I had a Porsche 911S that ran Great, if I ran the H out of it. Original owner, ran it daily on the Autobahn. This is the BEST engine oil video ever!
Back in the day (before synthetic oils) the recommendation was to change oil every 1,000 miles and the filter every other oil change. It didn't take long for "car guys" to realize that when you didn't change filters, you left about a half quart of dirty oil in the engine. On the other hand, when synthetics first became popular, some companies recommended changing only the filter every 2-3,000 miles and topping off the oil level. Doing anything besides an oil AND filter change is jumping over dollar bills to pick up pennies. Regular oil and filter changes are the best insurance you can get for long engine life.
I had a smile on my face just watching this and learning so much.
Lake is the man loved watching his dad race back in the day !
Lake's sr. awesome man, I raced karts with him in the 70s. Mark Dismore, Gary Hartman, Rudd . D Grenier. Lake sr. allways a kind person .
One of the best Daves Automotive videos. Ends all the know it alls sealed for life no need to change the oil, extended oil change intervals. Great job.
What a great collab! Been watching Lake for a long time... learned so much and now even more in this video with the great questions. When I first discovered Lake, his video reaffirmed by strict usage of Pennzoil Platinum (started using at 90k and now 212,000 and counting in an LS w/DOD (disabled, but parts still there)!).
Thanks for sharing. I’ve been following Lake since I seen his videos with Stapleton 42 on RUclips. He’s very knowledgeable and smart just like his dad. I’ve learned a lot from him even though it makes my head hurt.😀👍
WOW, That was a master class.
Now if you excuse me, I'm going to get my oil changed.
😂 thanks for making us laugh 👍
LOL
😂👍
I work for a commercial farm, and I couldn't believe that some of these trucks were still running with engine oil that has been in the engine for Years...I mean chunky style "coal tar"..( Early 2000's GM V-8 products) ..so I drain them and do thin oil with Seafoam to wash them out then new filter & factory spec oil...and I'm so impressed with these "newer " units, oh why did GM go to such a small oil filter? They are the size of a 20hp Kohler oil filter...but im totally impressed on how these units hang on without real attention, .thanks for the tech info here Gentilemen.
A PF63 is fine if the oil change interval is correct... which is about 3000 miles earlier than the oil life (lie) meter. Funny enough GM trucks sold in the last few years have an oil life meter that is programmed to hit 0% way sooner than GM trucks sold 10 years ago. The biggest thing causing damage on GM engines today is that guys believe the lies on the jug of oil that claim it's a 7k or 10k mile oil. Especially if it's an engine with AFM lifters. Gotta keep the oil clean for those lifters to be reliable. Now that the HD gassers have the same direct injection fuel system and AFM, you gotta change the oil often. Change it as often as the old timers changed oil and don't worry so much about oil filters because the soot that DI engines make is almost identical to the soot that diesel engines make according to Lubrizol. That soot ends up in the oil as does unburned gasoline and causes most of the problems that people complain about with GM V8's (and their DI passenger car engines). That soot is so fine that there isn't an oil filter sold for gasoline engines that can capture it.
Dave, That was an absolutely amazing round table discussion you had with Mr. Lake Speed! I'll probably watch this again to make sure I fully understand the plethora of knowledge bestowed on me just know.
Two of the few guys, this senior admires & respects.👍🇺🇸
Wow, what a video. A video that every engine mechanic needs to watch. If they think they are a good mechanic now, after watching the video, they will become a much better mechanic. So much knowledge to soak in. Great meeting Dave, keep up the good work. Just love your video's, glad I found your channel.
Glad you enjoyed it!
This is awesome Dave, this speaks incredible volumes to you as well as your shops humility to learn and constantly improve upon your services and products. Thank you for not shying away from your faith when so many on the internet do and teaching a young twenty year old man from western NC, 28040.
Much appreciated!
To me, the conversation was so exciting. To hear experienced experts talk about engines and engine oil. Thank you!!
I could listen to these guys for hours. A ton of useful information for my Diesel TDI
Take notes folks. All I heard is real people here vs corporate America trying to take your money and play the system.
Man-Oh_man! I enjoyed watching you guys sitting around, talking moto-geek stuff so much! I have been following Lake for a long time now and learned a lot from him, but seeing you guys talk about how the oil actually fits into the scheme of things, especially as an engine builder, was just really remarkable. I hope to see more of this kind of shop talk with others that are "Best in Class" of what they do. Lake was a really good choice and guest. Thanks again!
That is awesome!
Thanks!
Dave!!! Your transparency as a business man is honest and fantastic. You are a true mentor of how a business owner and sales should be. Good job 👏
I started watching your channel 2 or 3 months ago i have learned a lot and I'm sure many others have to. I just want to say thank you very much You all are 100 percent professional God Bless you all
Awesome! Thank you!
Fantastic video guys! I have worked with a high end manufacturer for 37 years and you guys are spot on!! You men made some great tips I wish more vehicle owners knew, especially about oil change intervals and pampering your engine too much. This seems to be even more important now than with older engines without direct injection, turbos, etc..This applies to both diesel and gasoline engines. Thank you for making these great videos!!
Best channel on RUclips regarding autos, so glad I found it. You guys are the best, and honest. Thank you.
Appreciate that
Great and highly informative video. Used to rebuild motors and hearing how the additives actually work from a guy who designs them is something I wish I knew more about back in the day.
This was beyond awesome. Really happy to see all u guys together. Would watch again definitely
