The Great LT1 & LT4 Oil Confusion // When to Use Which Oil & Filter // Breaking It All Down
HTML-код
- Опубликовано: 1 авг 2024
- Have you ever wondered why your 6th Gen Camaro owner's manual tells you to use a different oil viscosity based on what year your car was built? Why does the 2023 say to use DexosR, and earlier years tell you to use 5W-30, 5W-40 or 0W-40? When should I use 15W-50 and why? Why is the PF64 the right filter and the UPF64R is not recommended? I answer all of these questions and more in this video. This information applies to the LT1 & LT4 engine in the Camaro, but also has applications on some Cadillac's, and any other performance oriented, track-used vehicle.

The 2023 Camaro track prep guide says 15W-50 for ZL1 1LE only. Does give the option of 15W-50 if 0W-40 not available for SS1LE. I can’t find anything about 5W-50
Technically, it’s “required” for the ZL1 1LE. This is taken directly from the high-performance supplement, linked in the description when talking about the LT1 and the LT4:
*15W-50 full synthetic engine oil may also be used for track use and is required on the ZL1 1LE, but after track use must be changed back to 0W-40 dexos2 for street use.*
This was confirmed by the GM small block ACE as well. You can run 15W-50 in the SS for track use, and it’s recommended if you will be running a more aggressive tire like the SC3R or a slick tire, since G-forces will be higher.
The 5W-50 is not in the manual because it was introduced and developed for the C8 Z06. This was also highly recommended by the small block engineer to replace the 0W-40 for 3-season vehicles that see a good amount of track use, but use street tires like the OEM SC3.

Awesome video. We have a 2023 SS 1LE. Dealer did the recommended oil change at 500. Part of the GM first service agreement. We will be using your oil and filter recommendations for future services.
I am old school when it comes to oil and filters. I try to be informed about technology improvements and wow, how technology in oil and filters has changed.
Thanks again for a great video with pertinent specific info for cameros.
Agreed. Did your dealership actually use the Mobil 1 0W40 Supercar oil?
I wanted to take advantage of the included first service we all paid for when buying our cars, however when I called them they seemed clueless. I fear many dealerships may just throw in some of their bulk 5W30 or something to cheap out. May just spend the money about a $100. or so for the 10 quarts and do it myself which I do anyway.
@cardo1111 on my 2018, the dealership I took the car to did not, and I made them drain it and refill. I had to show them all of the addendums to the 0W-40 for them to do so.
When I bought my 2022, I worked with an incredible dealership out of Detroit (Matick) and I was there long enough to have them do the 500 mile change. They showed me the 55 gallon drum of Mobil 1 0W-40 they had for the Camaro and Corvette, and even walked me around the service shop while they changed my oil.
Some dealers know exactly what they are doing and care about their customers and unfortunately, some don’t.
Excellent video thanks!
I appreciate that!
Thanks for sharing this helpful info. I didn't realize the psi ratings for the oil filter bypass valves 👍🏽

As of 3 July 2024, there is a MOBIL M1114A Synthetic Oil Application; 25 PSI by-pass valve Oil Filter available on Rock Auto if anyone is interested.
Glad to see Mobil 1 has an updated filter for this application
Dropping a like! Good video bro.
I have been using 0W-40 supercar in my 23' 2SS 1LE, but I have to get it online. No store carries it around me. I am hoping it gets a little more common and ideally cheaper, but I am not getting my hopes up lol. I have been using the M1-113A filter but I will be switching to WIX WL10290XP! Thanks!
Thanks! I dropped an Amazon link for the 0W-40 and filter bundle in the description. It’s from Speedway Motors, but without the shipping charge so it ends up being cheaper. Definitely swap to the WIX or PF64 filters! Glad I could help you in that regard.
With oil and racing, I have learned a lot through trial and error, analysis, and friend experiences. I have a simple model and myself and all my lt1 and lt4 friends follow it for track use. I'm talking time attack and some medium length practice sessions. Really never more than 15 to 20 minutes of hard track drive at a time. Keep it simple.. for the Lt1 and lt2 0w40 m1 euro spec with best fram filter (disagree or not it's the best option) or if you can't fram then oem filter and for the lt4 15w50 racing m1 and best fram filter. Street use just use 0w40 x3 all the time both engines. Change after every big weekend event or 3 auto cross events. Really what I watch for is how hot it gets. If in cool weather and temps never get above 260 then i run a little longer. If i see 270 to 285 i change it before next eventb. I have 12 oil analysis doing this with a few oils. 15w50 wins every time in c7z and 0w40 euro spec in lt1 cars. Although I did just buy a bunch of the 5w50 supercar. Scared to use it in my time attack c7z. 650 wheel hp e85. Btw fram xg12060 is 19 to 25 psi. Switch and do an analysis back to back. I did 4 times cause the ac delco was brought up so much i was doubting fram xg12060
I don’t disagree with what you are saying at all, I just wouldn’t trust that Fram filter haha. Plenty of others have tested Fram against others for filtration and flow and it’s never been on top.
I been using kn hp-1020 oil filter.
I just check and pressure relief valve is 22-28 psi. I also use the mobil 5w50 here in Florida with no issues!!
Sounds like a great combo for that environment!
Excellent video! I bought the supercar 0/40 but will use the 5/50 next time. I’d like to see you do a video on the ZL1 Addons rear toe hook ?
While I’d love to do that someday, in the meantime check out the Racing for ALS channel, as they have a GREAT video on that! Here is the link: ruclips.net/video/KzD7Gmpppak/видео.html
Of course I’ve been doing it wrong. Used and have many quarts of the European formula plus I have been using the AC Delco UPF64R filter. 🙄. Glad I didn’t use the K&N Hp-1017 Oil Filters that someone gave me. Yep 15 psi. Thanks for the great video!
In your case, the filter is more important than the oil. That oil will be fine occasionally. Just make sure you’re using the correct stuff going forward and you’ll be fine.
I’ve been using the mobil 1 European formula along with the acdelco oil filter and it’s been doing great for now. But definitely would like to try out the supercar
You should do an oil sample analysis between the two and see the differences.
Outstanding rundown of these oils for the Camaro. Only one correction: you mentioned the track prep guide calling out 15W50 for both SS and ZL1 and it does not. It says ZL1 and 1LE meaning ZL1 1LE due to tires and suspension pulling more g's. Same for Z06. Thanks for a 1st class video on this stuff. I'm definitely changing to 5W50 supercar as well.
Thank you! I appreciate that. Regarding the correction; Page 13 of the performance supplement calls out the LT1 and LT4 can use 15W-50 for track use, but that it is REQUIRED for the ZL1 1LE. I cleared up the confusion here with the GM small block ACE by asking him this directly.
@@FollowMyLine17 Exactly... small minute details. Your video was so spot on it's the only thing I could question. Subscribed!!

Absolutely. I run it year round too, but it’s -10° right now, so she’s in storage 😂

Thanks. I am aware. I also know the Lingenfelters personally, and I see they are running Amsoil now.
You have a very good post here. Very informative and factual. Thanks for sharing.
@@oilman1 thank you very much!
Great job on the video! I use the SRT filter on my Charger, I will have to look up bypass rating. Do you follow the Bob is the Oil Guy forum? You might want to join and post this video, that group would enjoy this.
Thanks! I don’t remember the specifics, but the SRT filter is what I used in my R/T and Scat Pack Challenger. Bypass valve specs were what was designed for the engine, and the filtration and construction of that filter was some of the best in the business.
Great vid, thx! Curious about a few things. Have 2023 2ss 1le. 1) using 5w30 oil for non-track car vs 0w40? 2) dexos1 vs dexos2 vs dexos3? My manual says dexos1, but read dexos2 or 3 likely better.
Your vid’s have really helped me take better care of my Camaro. Thank you!
Sorry, meant dexos1 gen 3 vs dexos2
Hey! Your 2023 SS 1LE calls for 0W-40. A 30 weight oil is too thin, even for regular street use. I’ve updated the description and a link to the track prep guide is included. Factory fill and everyday oil should still be 0W-40 ESP Dexos 2 -OR- 0W-40 Supercar Dexos R. The differences in Dexos 1 Gen.3 and Dexos 2 are really certifications for oil manufacturers to be suitable for use in GM engines. The Dexos 1 Gen. 3 is a newer variant designed for the smaller turbocharged engines.
Awesome, thanks!! Matt
I think as long as you change your oil filter every 5,000 miles or less... It should never get clogged. I have rotated back and forth between Mobil 1 and Fram Ultra... You can't beat the price at Walmart.
The chance a filter gets clogged is fairly low, but in cases of extreme heat (track use) this can happen more frequently than it would ever happen street driving. The biggest thing to take away from this is that you don’t want a filter with too low of a bypass rating, because it can cause dirty unfiltered oil to go back into the engine. This wouldn’t be a huge issue if it happened once or twice, but repeatedly it could lead to extra wear and tear on the engine and possibly premature failure.
I did not know about Supercar 5W-50. I have been running 5W-30 and the Mobil 1 filter because I thought it was better. (2018 owner's manual I did not know about the update!)
I will be changing.
1 question that is somewhat off-topic: do you run a catch can? There seems to be endless debate online. I track my SS 1LE a few times a year and had one installed, but the car was smoking at the end of long sessions. I took it off and have had no issues since. But according to the forums we need one to save the intake valves.
You are very knowledgeable and well-researched, I'd just be curious what you do. Maybe you could make a video to share your thoughts.
Another video idea would be to go through your garage. It looks like you have a sweet setup!
Thank you for your fantastic videos.
Thank you! I definitely have an opinion on catch cans. They do not belong on the car, ESPECIALLY if you track your vehicle. Some catch can manufacturers call that out, but most do not because they just want to sell you product. The intake valves will stay clean if you drive the car hard every once in a while. You made the right move by removing the catch can. I’ll have to think about making a catch can video, because I am not sure I can handle all of the misinformed comments about having one being better 😅. My garage is decent, but maybe once I get some sort of lift installed I can make a video about the garage! Thanks for the insight and support!!
@@FollowMyLine17 Awesome, thank you for the reply! And yes the comment section might get out of hand 😅
The internet catch can porn has gotten out of hand. The Corvette chief engineer has been asked about catch cans many times. His answer has always been we ran LT 1 and LT 4 engines an equivalent to 200 k miles and there was no significant carbon buildup on the valves. Catch cans are unnecessary.
100% correct. When speaking to the small block team at GM, they said the OEM system handles oil blow-by as intended up to about 1,100 horsepower. Zero need for a catch can on a stock powertrain.
Great video but can i get your opinion? I have a 2016 ss and it’s cammed with all the bolt goodies on it and i take it to the drag strip couple times a year. Will the 5w-50 be great for situation? I also drive it every other weekend on the street
It could be, but there are so many variables to consider with a modified engine. I would recommend talking to your engine builder and see what they suggest, since they would be the most familiar with your build. The 50 weight oil may be too much, and they may recommend something more like 0W-40 or even 5W-30.
Great video I was on the fence because of facebook know it alls but ill be using the mobil 1 esp 0w40 from autozone because of their deal its dexos2 an 0w40 should be fine for a 21 LT1 right ?
Yes, absolutely fine! There have been updates made since the original launch of this video.
The ESP X3 European formula is Porsche factory fill and actually a better oil than the Supercar 0W-40 in my opinion. It carries Dexos2 so it’s safe to use.
The older Euro formula had much higher levels of calcium and wasn’t great for direct injection engines (LT1/LT4 are DI) but since the Supercar formulas have been released, Mobil 1 changed the formulation on the Euro ESP to meet Dexos 2. I would personally stick to the Supercar formula, but that is just my personal opinion.
@@FollowMyLine17 Yeah, the Euro FS formula is a separate thing, it's been updated to SP now so has half magnesium. The high calcium wasn't a problem for DI alone though. The high calcium is only an issue with small engines that are highly turbocharged in combination with DI. It would have actually been fine for an NA engine. The ESP X3 is also a development of a separate program funded by Porsche separate from the other ESP Euro oils. I spoke with the program lead on that briefly. I can't conclusively say it is better than Supercar but it is higher HTHS and I do believe it is likely to be better overall. Still, we're splitting hairs here. The Supercar 5W-50 is the real star if you can tolerate the low detergent levels.
@@chrisbradley3224love the input Chris! I did recently get my 5W-50 analyzed and everything came back fantastic. Maybe I’ll do a followup video covering the data.
I have a 2016 2ss and I've been using the purolatorboss oil filter PBL11403. It says bpvs (which I'm assuming stands for bypass value system) 25. I don't track my car but I do run it fairly hard in Foothills. Would you consider that filter acceptable?
Yes, the Purolator bypass valve at 25 psi is in the safe range between 22-30 psi. Purolator is made by the same company that makes the WIX filter, Mann+Hummel.
Great video . My shop uses the 5-30 on my 23 ZL1 with the PF 64 . I live in South Carolina . Do you think this is good ? Much thanks
Really depends on your application, but if the engine is stock, you should be using the 0W-40
@@FollowMyLine17 I change it at 50% . I’ll have him do it then . Again much thanks
@@FollowMyLine17my car only has 2500 miles on it . Oil has been changed 3 times . For breakin . I will continue to change oil with the WIX and the 0-40 u recommend when the computer says 50% (+or-) oil life is left .
Any issues using Fram brand Oil Filters? TG or XG12060?
I personally haven’t run the Fram filters, but historically speaking they aren’t the best constructed filters. Checking the bypass valve pressure rating would be the first step. If it’s within that 22-30 psi range, it should be safe to run.
Does the thicker oil drain back through drain holes, in heads properly?
Yes, there is no issue there. Keep in mind, GM recommends 15W-50 for track use in their high-performance supplement on the SS 1LE and ZL1, and it is required on the ZL1 1LE.
So would it be okay to use the Mobil 1 esp 3 European formula on my 2023 camaro ??
You can, because it is now Dexos2 certified.
Filter bypass is minimized by not over extending service intervals. Cut open some filters and look - AC is ok, Fram is a joke. Also note that 15w50 contributes to cold start scuffing, reduce its use to race day or very warm climate.
All true statements. GM recommends using 15W-50 in both the LT1 and LT4 for track use and swapping out after. I am running the Supercar 5W-50 developed for the C8 Z06, on the recommendation of GM engineer friends.
Would 15w 50 damage catalytic converters or anything else ? Can it be run all the time ? Do u prefer the 05w 50 in South Carolina 4 seasons ?? Or should I stick with the 0w 40 4 seasons ? Thanks . I’m spending some time on this and hear some different things so I’m kind of now just sticking with your info u come across much better and more factual than other people and their I think so opinions . 👍
I appreciate that! As far as 15W-50 all the time, I think you do run the risk of some cold-start internal engine marring, however, many have run the 15W-50 full time without issue, especially since many of these cars are purchased as track toys. If you are using yours on the street primarily, I would stick to the 0W-40 and switch to 5W-50 for track use (or 15W-50 if it’s a ZL1 1LE.) If it sees more high-G loads than grocery store trips, than running the 5W-50 full time is not an issue. I currently run 5W-50 full time, but it’s also not my daily driver. It sees less than 5K miles per year, and most of those are trips to and from the tracks I drive them to.
@@FollowMyLine17 ok 👍 thanks . I’ll do 0w 40 . I only drive a few hundred miles miles a year
I believe that mobil 1 upgraded M1-113a to a M1-114a Extended performance which has the 22psi bypass valve.
update M1-114A bypass is 25psi
Interesting! Great find, but I do not see the M1-114A listed as compatible. I’d love to do more research myself. Thanks for the tip!
I wonder with the 50 weight oil, will the 22 psi bypass oil filter, be in bypass mode to much? Also the WIX XP10290 filter has a 34 micron spec where the standard WIX10290 has a 20 micron spec and is less expensive. The WIX XP, is an extended life filter, I think most Corvette owners change their oil before 10,000 miles.
Great info! The 50 weight oil shouldn’t be an issue with the bypass rating, since the ZL1 1LE uses the same filter and 15W-50 is “required” for track use on that car.
I understand that, but just because 50 weight oil is used for track, doesn't mean it isn't in bypass mode. Track use is very temporary and the temps are way higher than everyday driving.
@@dkevvv I completely get what you are saying. I’m actually going to reach out to my smart friends at GM and some other places to get their thoughts on this, with that filter.
Thank you for the video. Very informative.
You mentioned a Patrick who blew his LT1 engines. Do you mind explaining what happened so that we can learn from that unfortunate incident?
Thanks
Hey! Thanks for the comment. Regarding Patrick, he was running Goodyear SC3R tires and pushing his car to its limit at Sebring on the factory fill 0W-40 engine oil. This happened to both of his cars. He has since switched to Mobil1 15W-50 without issue, and these engine failures are what stemmed our conversations with the GM small block team.
@@FollowMyLine17 oh ok so like your video says I should stick to then factory 0w40 since I’m running the OEM SC3 and I plan on doing two track days a year my first one being Watkins. I’m a newbie. Or Should i do the 15w50? Or stick to 0w40?
Also thank you for your how to videos. They were really helpful. I’m now subscribed to your channel and I look forward to your next video.
@@pv4083 you should be fine with the 0W-40! Watkins Glen is one of my favorites. I’ve been there twice. You’ll have a blast.
@@FollowMyLine17 thank you. I’m excited
@pv4083 thanks for the sub! Looking forward to your Watkins Glen experience. Let me know how it goes.
is Pennzoil ultra platinum 5w30 good for these cars? watches an oil comparison video by project farm and ultra platinum did great, i noticed that the 5w30 is dexos rated but the 0w40 has no dexos rating and says srt exclusive... i wanted to run 0w40 since its been super hot lately and im procharged. i ended up going with the supercar mobil 1 0w40 since the Pennzoil said srt exclusive and has no dexos rating...
You’re better off running the Supercar or anything with the Dexos R rating. To be fair, Project Farm didn’t run any of the Supercar Oils. I made the suggestion to him to run all of the top oils like Supercar, Amsoil, Penzoil etc.
I think the Mobil 1 engineers built the lower bypass pressure into the filter to allow flow under very cold start conditions. If you change your at recommended intervals oil bypass due to plugged filter media is not an issue unless your engine is coming apart. The cold start prtection is much more important to reduction of engine wear.
They may have, but it’s still far too low for the safe range in the LT1 and LT4. Too high of a risk to get contaminated unfiltered oil in when the filter isn’t necessarily clogged. If the bypass is opening for cold starts, I’d argue that isn’t a very good design to begin with and you may have something wrong with your engine anyway for it to build that much pressure in the filter on a cold start.
@@FollowMyLine17 Thanks for your reply but I just don't follow your logic. If the filter is not clogged there is no danger of the bypass opening and the engine getting any unfiltered oil. Only if the media is clogged or the oil is so thick it builds up pressure in the filter will it bypass. At this point it better to have unfiltered oil going to the engine than little or no oil. A high bypass pressure setting may severely restrict the oil and ruin you your engine even if that trickle that gets through is "filtered."
@@jamescherney5874 I’m saying that if your oil is so thick on cold start that it’s triggering the bypass valve from pressure, you have bigger problems. Yes, I agree with you, if the bypass rating is too high, you run the risk of oil starvation. That is why the UPFR64 is not recommended, for example, since it has a 35 psi rating. The max filter bypass psi rating for the LT1 and LT4 is 30.
I agree with what you just said. The biggest problem you are going to run into that would restrict the filter is thick oil caused by low temperatures. What temp is this. I don't know. You would have to test different viscosities at low temperatures to determine what is a good bypass differential to build into the filter. I don't know where you got the 30 psi rating for the LT 1 and LT 4 engine. I doubt it came from Chevrolet.
@@jamescherney5874 did you watch the entire video? The information came directly from the GM small block team, through multiple meetings I had with them. Over 3 hours worth of meetings. The safe range for the LT1 and LT4 on the filter bypass is 22-30 psi.
What about amsoil 0W-40 and the amsoil filter?
Amsoil 0W-40 meets or exceeds the Dexos 2 requirements. I cannot speak to the filter. If it’s within the safe PSI range than it should be fine.
The GM manual for '23 states 5W30 that has the dexosR designation may also be used for street only use. Is there such an oil out there, or just another GM manual misprint/mistake?
There currently is no 5W-30 viscosity Dexos R rated oil, as of Dec. 2023.
Bought my Mobil 1 0W40 Supercar oil through Wal-Mart $10./QT, they're listed as an online retailer on Mobil 1's website. Trust them more than a random online reseller not on Mobil 1's website. Even though GM includes the first service, when I called the dealership inquiring about the oil they would use, they just said a full synthetic Mobil 1. I hate to say I just don't trust 100% they would use 10 quarts of such an expensive oil for an oil change they usually quote about $100. to perform. I appreciate the response.
@@cardo1111 I’ve used Walmart before. Amazon usually has great deals on 0W-40 as well. This one always works for me:

The Mobil 1 filter you show in the video is NOT the recommended filter. It is actually the M114A which does have the correct by pass valve rating for the LT1 engine.
The M1-113A actually IS the recommended filter for the LT1. Any cross-reference you find for the LT1 and PF64 will show this filter, and that is why it’s in the video. Great find on the M1-114A though. The M1-114A is recommended for the LT2 on the C8 Stingray/E-Ray. It ABSOLUTELY WILL fit the LT1 and is the correct bypass, as you mentioned.
@@FollowMyLine17 I agree that a lot of literature shows the M113A as the correct cross to the PF 64. However, I just looked up the car in the 2024 Mobil 1 catalog at the parts store and that did show the M114A as the correct filter for the LT1 engine.
@kylejohnson9294 that is great news! Hopefully parts stores can start updating their online databases, too. I wanted to make sure people knew that the M1-113A was not a good option, and the reasons why. That is why I included it in the video. Obviously as time passes on, things in this video may start to become outdated. The main fundamentals of the video however are still accurate.
Mobil changed manufacturers for their filters to Mann & Hummel. After that, the filters changed. GM uses the pf64 for the vast majority of their lineup. My Regal used to use the 113a filter until a few years ago, and now it takes the 114a. When you call Mobil's customer service for filter info they tell you the website is wrong, and you're actually routed to M&H support.
@JustNotAndy excellent!
So I have a 2016 ss should I used the 40 or 30
0W-40 is what is recommended for the LT1.
So the heavier oils are for g-forces. I always thought they were for the 300F+ oil temperatures.
In this case, that is a good way to think of it, although you wouldn’t want to put something like 75W-90 in your engine even if you ran it in the Sahara Desert. Heat/Temperature breakdown will have more to do with the composition of the oil itself. For example you can have a 0W-40 sustain the same high temperatures as a 5W-50 just as well or better, depending on the oil.
I just purchased a 2023 SS when do you recommend doing the first oil change?
GM says 500 miles
I linked the track prep guide in the description. If you plan on tracking the car, the first change should come at 500 miles, like anikhem3637 mentioned, and then again at 1,500 along with your differential oil. If you don’t plan on tracking the car 1,500 miles is fine.
Thank y’all
The Euro ESP is the x3 correct? It's also SN+ rated not just SN, correct? Another question: a Dexos2 rated 5w40 would also be fine in the LT4 where temps don't go way down below -20˚ F?
Yes, technically anything that is Dexos2 certified will meet the requirements set by GM to run in the engine, from a warranty standpoint. 5W40 would also be fine.
Cool, it just makes finding a good oil and deal easier.
@@gbass7328 if you are looking for a deal, you can get it for about $54 right now:

The mobil 1 ESP x3 0w40 is dexos 2 approved now so does that mean it would be fine for a 19 SS1LE? (WV car no emissions and catless) wondering because autozone has it in store 5qt and filter for 39.99 deal and had baught 2 deals for around 83 with a pf64 with each deal.
Yes, it is now Dexos2 approved. You can run it without fear of warranty claim issues.
Just did the same ! No issues ?
No issue.
As far as the oil filter goes, why does the Bypass valve PSI matter unless the filter gets clogged and makes the bypass valve nessasary? If you change your oil and filter regularly shouldnt matter what filter you use right?
You’re right, on the high side. The bigger issue is if the bypass setting is too low, you end up letting impure/unfiltered oil into the engine. For example, the Mobil 1 M1-113A has too low of a bypass, meaning you run a higher risk of the bypass opening too soon.
Understood. Love your channel brotha!
After watch a comprehensive oil filter test, the best one for cleaning your oil is the Purolator Boss, best at cleaning small particles, low restriction at cold and operation temp! The by pass should never come into play with normal street driving if you change your oil every 5K?
I saw that as well. Purolator Boss is also made by Mann & Hummel. Correct, under normal street driving with regular oil changes, a clogged filter should not happen. You still want to make sure the bypass rating is matched/designed for what the mfgr/engine calls for in the odd chance there is a problem with the filter.
What oil wpuld be best for a l83 with a lt4 blower for street use?
This would be entirely up to your tune and use case. Not entirely sure what would be needed for the 5.3L with the blower. The L83 typically uses 5W-30, but how you use that L83 now will determine your viscosity.

@@ebarton1475 that doesn’t surprise me, the L83 is used in several different applications.
Hello I filled my 21’ LT1 with esp x3 is this fine or will I run into issues ?
Technically, it is NOW Dexos certified. I wouldn’t personally continue to run it because of the different detergent levels in it compared to Supercar, but it will NOT harm your engine having it in there.
@@FollowMyLine17 ah ok I see thank you
I thought the 0w40 I get the green bottle from autozone was right but I guess you are saying it’s a “European formula”. I’ve been using it for 4 oil changes now should I stop?
You don’t have to “stop” because it’s still technically Dexos rated. It does have a different level of detergents in it so you could see long-term funkiness with the emissions systems. I would personally use the Supercar formula.
15w50 all the time 👍
Mostly track use?
I drive a 2023 camaro SS. The oil cap says 0w-40, but I don't track and only drive on the street in which I only drive 3 days a week. Is it necessary for me to use 0w-40 or can I use 5w-30 dexos1??
Can you use 5W-30? You can, but I would highly recommend sticking to the factory fill 0W-40.
@@FollowMyLine17 much appreciated 👍
Just got a 416 bottom end put in what oil/weight you recommend some people say 20w-50 5w30 or 15w50
That type of application will rely on the bearings used vs the crankshaft clearances, what, if any, oil circuit modifications, the cooling system setup (oil and water) and intended use (low vs high RPM, drag vs road race).
Oil is another "coolant" for the engine, a lubricator and a "hydro-dynamic" spacer.
@MalikB_1ss that would all depend on application. As @SocketToMe stated, there are lots of variables. I would reach out to your engine builder and see what they say.
@@FollowMyLine17 engine builder recommended 5w-30 but gpi recommended GP-1

Why not look into the PF63... It's the taller version with a 22psi bypass rating!!
You absolutely could as long as it’s the newer PF63. The older version only had a 12psi bypass rating. It doesn’t hurt to have more filtering capability, but as my oil analysis’ have found, it isn’t really needed. As long as it doesn’t hang below the oil pan, it should be fine.
@@FollowMyLine17 I've found that as well but I do like the value of a bigger filter... Nice video btw
@uglyhandgarage2927 thank you! I appreciate it.
Its not just about EPA, its about internal clearances where oil need to get in for lube. For instance a 50 weight oil in a normal LT1 is overkill. You will get better lube with a 30 weight rather than a 50 weight.
For regular street driving, yes, 50 weight is overkill. If you start tracking the car hard, or on slicks or a competition tire like an SC3R or Cup 2 R, the 50 weight will save the engine from unscheduled rapid disassembly.
This is a myth. As long as you’re not in bypass and the startup temperature is ok for your winter grade then the thicker oil is fine. Oil is pumped by a positive displacement pump, if the oil was too thick for the galleries you would have super high oil pressure.
I bought a 2018 chevy camaro 1lt the v6 version and I've been so fucking confused as to what oil and oil filter to use.
The 3.6L V6 uses 5W-30. You can pickup an ACDelco PF63 filter here: amzn.to/3R3rdS7
Or a WIX WL10412 here: amzn.to/4a1uzNT
@@FollowMyLine17 the original manual I have for it says it uses the pf63e oil filter.
The standard PF63 replaced the Ecore (PF63e) filter.
Mirrors very similar another Mobil 1 partner, Porsche. 0w40 A40 or 5w50 A40. I do often wonder how much the EPA rating conspiracy theorists have a basis in fact. Super interesting that the ESP oils or low - mid SAPs oils are becoming popular for the latest GM products. Ooil chemistries are getting magical with the lower sulfur fuel.
In theory as thin as possible, as thick as necessary.
What about royal purple
You would have to double check their specifications, but my understanding is that the RP 0W-40 does not meet Dexos2 certification. I could be wrong and they could have updated the formula. You may want to reach out to Royal Purple direct and ask them.
@@FollowMyLine17 I don’t worry about emissions but I primarily use they’re 5w30 and I was looking at possibly going 0w40 in my 2017 Camaro ss
@kaliph013 well, then you can use the Royal Purple without worrying about any warranty because even your powertrain warranty is up. RP makes good stuff, so I’m sure you are absolutely fine to use it. Just try to find a suitable viscosity for what your use case is. Cruising, drag racing, Road course, etc.
@@FollowMyLine17 I daily it but it doesn’t get lower than 30 degrees where I live but I race it as well what’s ur opinion on what oil I should use I also run k&n oil filter
@@kaliph013 it entirely depends on what kind of racing, which tires you use for racing, any aero setup, the tracks you go to if it’s road course racing, etc. The 0W-40 should be fine until those other factors come into play.
There is some bad info in this video. I don't know how the notion that high viscosity is important because of "high-G" turns, but that's just ridiculous. It doesn't matter how many Gs you pull for how long - if your oil pickup becomes starved your engine is in trouble, and higher oil viscosity won't keep it from getting uncovered. Higher viscosity generally provides more kinematic viscosity at high temps and in high-shear conditions, which IS a thing during track use! That's the ONLY reason a higher-vis oil is often recommended for track use. The downside has a lot less to do with gas mileage (honestly, it probably makes no measurable difference in an LT4) and a lot more to do with cold startup protection. The 5w50 oil has about twice the viscosity at 96F as 0w40 ESP or Supercar (it has almost as high a 40C vis as the 15w50!), so it will literally take twice as long to reach all the important parts of your engine on a cold start on even the hottest summer days. In addition, the 15w50 is not Dexos 2 certified and does not play will with your catalytic converters or especially your intake valves on DI engines like the LT1/4. That is why you shouldn't keep it in your engine for regular street use. At least the Supercar 5w50 doesn't have that problem. But yeah, if you keep 5w50 Supercar in your car all the time and use it for regular street driving, every cold start is creating more engine wear than if you used 0W40. If you only drive your car once or twice a week, do a lot of track time, and have a different daily driver; then maybe 5w50 is a good option.
Finally, the x3 version of 0w40 ESP (the "European" blend) has better specs than the old ESP or Supercar 0w40. You can see that in its higher 100C kinematic viscosity and its higher high-temp/high-shear viscosity. So it will do a better job on track than Supercar 0w40 but still give you much better cold-start protection than 5w50.
It’s not “bad info” it’s just information you may not agree with. I’ve put as much of this info into terms most people understand and giving examples that make sense in real world conditions. I know you have done a lot of your own research on this topic as well, so I don’t want to sound dismissive of your comment.
The information I am providing came directly from the small block team at GM. I didn’t pull this info out of a hat, and the examples given in the video were examples given to me during the several hours of calls I have had with that team in the past.
Yes, 5W-50 will not offer as much cold weather or startup protection as 0W-40 and “could” take twice as long. The time you are referring to here is fractions of a second. Not minutes.
While I absolutely appreciate your info, I will stick to what I have been told by the engineers at GM who designed and built the LT1 and LT4.
@@FollowMyLine17 there are opinions that are open to agreement/disagreement. What I'm talking about is facts, which are not open to disagreement (unless one does experiments to disprove them). Viscosity is _literally_ the measure of how fast a fluid flows through a given orifice. So when M1's own data shows that 5w50 Supercar has a 40C kinematic viscosity of 111.8 mm2/s and 0w40 Supercar has 69.0 mm2/s, that means the 5w50 _literally_ takes 62% longer to reach parts after a cold start at 104F. That's not a matter of opinion. And if you think it only takes "fractions of a second" for this to happen, then I invite you to let your engine sit overnight, remove a valve cover, and time how long it takes oil to start flowing through the rockers after you cold-start the engine.
As to the stuff about uncovering the oil pickup in hard cornering, apparently some GM engineer did say that. I've seen that conversation referenced elsewhere. But that's just plain silly. The higher 100C and High-temp/High-shear viscosity of the 5w50 or 15w50 is preferred for track use in the LT4 because of the extreme heat, pressures, and shear forces inside that supercharged engine during extended lapping sessions. Again, these are just facts.
I want to emphasize that I agree that even an LT1 car driven mostly on track days will probably benefit from 5w50. But if it's a daily driver that sees occasional track use, 5w50 will allow more damage at startup than it will solve on track. The best option for those cars - other than changing to 15w50 just for the track day and then changing it out again right after - is to use the "European" 0w40 ESP x3, which has a better HTHS viscosity than the Supercar 0w40. It at least gives you better track protection without sacrificing cold-start protection.
100% wrong on the filter bypass setting. The setting is what the media can stand, it has zero effect on oil flow. With a positive displacement pump, you will never lose flow or pressure, it will collapse the media if the setting is too high & that will never happen because that is taken into account when the bypass value is set. GM has specified higher bypass values because the oil pump relief is no longer at the pump, it is at the other end of the galley, so the pump is pushing full volume/pressure through the filter until the relief sees pressure & opens to relieve it. In all cases that filter is taking everything the pump is outputting, no relief valve at the pump to stop it. Most every filter will bypass on cold startup due to thick oil not passing through the media & opening the bypass. The fact that the Delco Gold is set so high is a testament to the media being able to withstand that amount of differential pressure. It could also mean the efficiency is not as great as other filters because it allows for more flow. You are making it sound like the bypass valve is regulating oil pressure & flow, it is not. It senses the differential pressure between the inlet & outlet of the filter & allows bypass if that gets too high.
The bypass valve / filter are most definitely not regulating oil pressure. Not sure why you understood what I was saying in that way.
@@FollowMyLine17 You said if you use a filter with a too high bypass setting (15:46) it would impede oil flow & starve the engine for oil. That implies regulation of oil.
Well that explains why I blew up my engine. RIP $20,000
