Interesting test. I have been using STP oil treatment for over 40 years. I normally start using STP when the vehicle is around 75,000 miles. I have used STP on GMC, Ford, Volvo, and Toyota engines. Every engine has made at least 250,000 miles. I am currently using STP oil treatment on a Toyota Tacoma with 213,000 miles and a Ford Fusion with 127,000 miles with good results. I can't say that the engines had good longevity because of STP, but I can say that the additive did not harm the engines as some have claimed.
Is wynns oil treatment any good as claims to free up oil rings too, i have a honda civic 1.8 2012, been burning a some oil about a litre every 600 miles. This could help the oil consumption and wear too
Chris was year model vehicles are you using it in? I'm "thinking" about adding it to my 2011 GMC, 5.3 engine with the 5w30 oil thats recommended. I'd like your input what oil you are using in the Tacoma and the year model of it, and your results today.
@@jimmyworks3600 My 1998 Toyota now has about 226,O00 miles. The Tacoma still runs great and burns no oil. I sold my 2006 Ford Fusion back in April of 2023. It had about 150,000 miles on it when I sold it. The Ford Fusion was still running fine when I sold it. The only reason I sold it was because I got a real good deal on a Ford Taurus with 32,000 miles. I also use STP on my wifes Grand Caravan with 190,000 miles. I have had no issues using STP.
I been using STP conventional oil treatment for 40 years & have had no problems. It quiets noisey lifters & other worn parts plus it has antiwear properties. I have a 2001 Mazda mpv 2.5 with 250,000 miles on it, running strong...
I've used STP treatments all my life with every car I've owned, right now I own a '97 Ram 1500 with a 5.9 360 V8 auto and I use STP after every oil change. Well I wait about a month before putting it in the engine or about 500 miles or so, to allow the oil to work and thin out some. But right now my truck has 269,700 miles on it so far with the original engine and trans, still going strong, I can haul or pull whatever I want, hoping to get a few more 1000s mile out of it. So for me it has worked good over the years, adding life to every car or truck I've owned.
I've only used it once and I didn't have a problem with it will not once but I used it a couple times on a vehicle I had a 94 Ford Explorer ran it up to 500,000 miles. And I'm currently using it in my 85 Crown Vic no problems probably going to put some in my Honda after I change the timing belt
@@mechanicjesse5430 Cool, yeah before my Ram, I've mostly owned Fords over the years and got a lot of miles out of them too. Right now besides the Ram 1500, I have a Nissan Quest van, it's got 178, 400 miles on it so far and my truck has 271,100 miles so far and both still going. Thinking about trading the Nissan off because it's been a pain to work on and still needing work done to it, but it's just my beater everyday driver and if it gets wrecked oh well I'll find something else kind of ride. But the truck means more to me and I hope to maybe fixing it up one day. Anyways I still use STP in both and hope to get a few more 1000s of miles out of them, if I don't trade the van off for something else.
I would actually call stp as the winner.i would want a oil that stays longer on the bearings for protection and not run right off like the Amazon oil did
Simple but effect test ,I've been using STP oil additive for years after my dad recommend it years ago when I got my first car ,I'm 49 and still use it
Back in the 80's, watched my Dad add a little blue bottle of STP at every oil change in a '83 Dodge Family Van. He always said it was the best 75 cents he ever spent. Got 200k miles out of the Van before it rusted away.
So I've had pretty good experience with the STP brand. The latest one I have used is the STP ceramic oil additive treatment. I'm now close to 2000 mile mark. And even before the 1000 mile mark I had noticed a increase in not only the power but the milage as well. Now this in my 04 I-6 chevy trailblazer. Hope your able to have fun and enjoy the product.
This was good, ...I thought STP is just polymers that would hurt the wear test but apparently the thicker oil and other additives that the polymers are suspended in helped.
I bought a used 99 Civic and hit the piston rings with some CRC-Brand EGR cleaner, let it sit over the weekend and then added STP to 0w40 (it gets cold where I live) and it stopped the blue smoke from the car at high revs. Thank you STP.
These types of videos are great. All I can add is I've used STP high mileage in my '95 Lumina and it has reduced oil leaks from lower intake manifold / front cover gaskets. Lifter noise is a little bit less. Zinc is probably good for pushrod engines especially ones without roller rockers. But you might want a non zinc version (Lucas) if you have a car with a catalytic converter. My 95' doesn't have an O2 sensor downstream of the cat so I'm not particularly worried if the zinc kills the cat.
Tried STP additives with stop leak on a 98' galant.. Results are a lot less leak under and no need to add oil every once in a while.. It works for some cases..
That was pretty interesting. If I do use STP, I usually only use it in the summertime. In the winter I use Rislone. A friends dad use that stuff for years, and swore by it.
For the most part I am not a fan of oil additives other than detergents such as Seafoam to help clean a neglected engine. Also, I have had good luck with Restore in older engines and it has been proven to significantly increase compression by several people. Other than that I'm not a fan. Think about it- If all these additives were really so wonderful and had no harmful side effects, why wouldn't high end oils like Amsoil already include them? A well maintained and properly designed engine will easily last several hundred thousand miles with no additives whatsoever.
AMSOIL sells their OWN additives.. (smh) Additives DO WORK, if you know what to use and how to use it. Plus is not like any company can just come and steal formulas left and right, these are obviously patented by their proprietaries and nobody likes to get sued for MILLIONS Of DOLLARS !
@1bad540i They have a huge selection from diesel additives to gasoline and gear oils plus their coolant additives and everything in between; racing grease, transmission fluid, limited-slip additives, brakes, etc.
Thanks for sharing this. I've always used the gold colored stp in my Harleys, along with Mobil 1, 20-50 MC oil. One Harley has 75K on it, the other has 106K. Neither have had a wrench to the motor. The gold stp has been in them both since new. Thx again.
My question is how much does the STP change the overall viscosity of the oil? If you use it with 0w20, does it change the 0w20 to approximately a 5w30 viscosity?
Used it both in the summer and winter without issues but am adding it to four or five quarts of oil not one! Use the silver bottle for small leaks and it works, but only use it once in a while.

I had a wesk oilpump in ,2007 gmc lifters started rattling bad on a trip i put stp in at gas station drove about two miles the engine quitened down and drove another 150 miles home changed oilpump and use stp synthetic treatment now with synthetic oil does fine with 50 more thousand miles
jeffcarpenter396, your post pretty much told me what I've been wondering. I have a 5.3 GMC engine, 2011 model, 157k miles. I'm thinking about adding STP at oil change but not sure about the tolerances and such of these new engines today. I have a lifter tapping at startup but goes away after engine warms up. I bet STP would stop that. Let me know more about your experience since we drive similar trucks. I'd like to hear how its going now and which STP oil treatment are you using? Gold can? Blue can?
Hey bud I will tell you something to look for these engines rocker arm and pushrods will wear out that might be something to check because if it starts up and rattles for a few seconds then the wear which creates a lot of clearance on the worn rockers and pushrods takes longer for they hydraulic lifters to pump back up they apparently bleed down while not running I had replaced these on a 2000 suburban with 289 thousand miles 5.3 ls
In '96 I bought a '94 GMC , 4.3 engine, truck, 55k miles. I used 10w40 and ALWAYS added STP. Around 250-300k miles it was a quart low at the next oil change. I changed to 20w50 Castrol and STP. After 21 years of driving it I sold it with 484k miles on it. I am sold on STP, yes. I have a 2011 GMC now and with these newer engines and their different tolerances I'm not sure whether to add it to my oil or not, so I haven't. But I'm thinking about adding it to my synthetic oil, I'm just not sure.
Nice. I only put half of the recommended on my cars as I thought it was too thick but after watching this video I'm impressed. I actually didn't even put this in my new tacoma, maybe I should. 🙃
I've been using it since I was 16 my first truck till just today for my jeep and honda ridgeline I live in death valley it was 110 today....I travel up the Sierra Nevadas in winter where its well below zero in I have had no issues ever.
Overtime or 3000 mile oil changes which is what's that's designed for it will, it would cut the wire down by half plus it has jink and all the stuff the EPA took out of the oil in the 90s which also helped wear any reason it took it out because they claimed it would harm catalytic converters the truth is that might but it will take 20 years for it to harm the catalytic converter in any modern car STP synthetic oil for newer engines with higher clearances company bearings and that's why it's thinner than the Lucas or the traditional blue STP so I've used it for years and not
It seems they got rid of the ZDDP when moving to Synthetic for newer engines, so...What's actually in it? Hard to find direct info apart from marketing speal, VOA analysis would be interesting.
STP Synthetic oil additive is an additive, BASICALLY it's a concentrated bottle of the synthetic ingredients found in the oil you buy. There is no comparable differences.
Another video did an analysis on stp, 8 ppm zddp and it increased the TBN with the non synthetic. And ya, 0 is the viscosity of water so 0w20 was intended for no higher than 68F per online viscosity charts. STP for summer uses, MMO for winter.
I've used the blue can stp for my moped in three different mc oil grades: 20w50, 20w40 and 10w30. Added in 150km after oil change of each grade and felt them all the same on clutch behavior and actual engine noise more like 10w30 amongst all grades.
It's basically Ester+PAO which has cleaning effect. You don't need to pay for this additives if you simply buy FULLY SYNTHETIC oil in first place which is made of Ester and PAO. Also, true synthetic oils ester and PAO have much lower pour point that normal oils around 30-40 percent. Unless you cool down the oils below -45°C, there won't be any different in the viscosity of both oils.
Most Fully Synthetic are now GTL paraffin or slack wax paraffin or hydroisomerised mineral oil paraffin. The days of "Real" synthetic oil are mostly gone except for a few specialized products like Mobil 1 0W16 or Amsoil Signature.The national advertisers agreed to call oil that performs close to a synthetic "Full Synthetic Motor Oil"
Thanks for your hard work, I liked your video, and w/o critisizing it, I think that this coul be a good series, perhaps adding a thicker version of the same oil (3 tests instead of 2), and testing different brands of additives to try to dettermine the best one. Once you find it, test varios oil brands with and w/o said additive...thanks!
I read Robert Sikorsky's books "Drive it Forever" and "From Bumper to Bumper" from my library many years ago. He was a member of SAE and wrote a column for the New York Times. his books were compilations of the NYT columns I think. One if the things he said was that the API American Petroleum Institute has NEVER certified any of the well known oil additives, not one of them. He himself I believe approved of Mobil One, and the Teflon additive, I forget the name, but I read those books in the 90's. I think he's still alive but likely too old to be active.
How did you manage to fit the1 quart of Amazon basics + 3 the ounces of the STP in the 1 quart capacity bottle? Surely the 3 extra ounces didn't evaporate. Explain.
We built a engine in a car & the r&r guy left the drain plug out & the owner drove it 15 miles home & complained about the oil light & clicking so he brought it back it had no oil except what it was built wt stp in the blue bottle! I know it sounds like a lie! But they filled it up & it never did give no problem!
I use stp oil treatment mixed with 10w40 in my 1994 gmc with a mild 350 small block. Truck gets worked hard off road and tows all the time. I feel as though the stp is good for it.
I live along the Equator....I think 5w30 is too thin for my car....[ our climate here ranges from 25deg in mornings to 36deg in afternoons ] ....wil STP thicker oil help increase the viscocity of the oil in my engine?
My 07 Bmw used to eat 1qt/1000miles. i added a bottle of Stp Smoke treatment and the oil consumption decrease to 1qt/5k-6k miles. the additive was pretty thick tho i think thats why
Stp synthetic oil treatment is 300ml wonder if much difference between the slick 50 premium synthetic oil treatment 750ml is any better? Just put stp oil in my 2012 320D touring as bought it with 130k mileage so just wanted to make sure my engine is looked after lol
Good video for those who are scared that it won't be capatable with their car due to the thickness. I believe it glings to the engine parts better than normal oil. I have a 2003 Cadillac CTS and when I put that new Lucas stabilizer for low viscosity, the car felt so much quieter. Not a placebo neither. I kept noticing it and noticing it. I'm like yo this car feels smooth right now. Not that it wasn't smooth already. But I definitely felt smoother. The car sounds like it's not even on. Also I noticed my acceleration had more power. Trust me. That New Lucas in the 12oz bottle is some good stuff. I was surprised. Note* what I did was do an oil change with STP high mileage synthetic & I used a Lucas Low Viscosity Stabilizer when I changed the oil. I do my oil changes every 2+3 months. Somtimes every month just to be safe. Oils cheap. Engine ain't. So when I tried the Lucas, it felt like a really good oil change. Trust me.
It was a pretty awesome video. I'm sold on the product. But this particular product is not available in India. How about the regular oil treatment (blue colour)? Any chance you could do a test on that please?
car : 2001 mercury grand marquise i just added this product ( LOOVE it) in kuwait its 54 celsius in some areas in 2pm these days summer and when i heat soak the engine (drive in traffic , accelerate hard and stop hard and do it again) the the valve trains begins to dance and jiggle (oil thins out so quickly ) i hate the new factory recommended motorcraft 5w-20 full synth with this product added engine sounds new now matter how hard i push the engine the new oil ford recommended is good only for winter add it gradually and slowly after it reaches operating temperature while the engine is running idle
Ive never used any type of additive with my oil changes, justmake sure to change them every 3k miles. I bought the car with 17k miles and now it's about to hit 77k, should I add some of these additives?
Please tell me: During the lubricity test, did the STP blend generate a lot of air bubbles? It is a major cause of oxidation and cavitation....was the STP blend foaming or bubbling?
I’ve only had one experience with stp 10w40 in my 79 gs1000 motorcycle. I always used Valoline but the store close to me only had that weight in stp and penzoil. I chose the stp and after one ride my bike was leaking badly from places it barely seeped from before. Not saying it’s a horrible oil but my advice is to stick to one brand because other brands contain different additives and chemicals that can cause weird stuff to happen to your seals.
My engine is starting to knock... hasn't been ran but a few minutes total since the slight knock started randomly one day... I about to add some of this to my engine. It's only 4 buck. And the engine is otw out already so might aswell.
I have a 2020 Honda Civic Sport Touring. I read the manual for the car and it says that no additives are needed for the car's engine. However, i've also read comments from other people where they've mentiomed that they've used additives on their cars about as new as mine including Hondas, and they were VVVERY satisfied with the results. Anyone care to weigh in...?
Good video, I've never used STP but have heard good things... Imo no need for STP if the oil your using has good chemistry and has high enough zinc levels already in the oil like 1100 ppm and above as long as you don't have a catalytic converter on your vehicle as the high zinc can clog the cat that's why they have lowered zinc level in the newer oils with SN Api specs. In vehicles and equipment with no cats this definitely could help if the oil your using doesn't have high Zinc levels already..... Only other concern would be COMPATABILITY of the motor oil and the STP components, I prefer to use a top quality motor oil like Amsoil ZROD with HIGH ZINC already in it so there is no problems with compatability of all the ingredients of the two products being mixed.....
its not that surprising since the oil you used was very low viscosity i am very sure though that if you used that stp on an engine requiring 0w20 it would do more harm than good since most of these engines have variable valve timing or/and hidraulic valve lifters plus there is a small chance that if the oil filter is small or of bad quality it would fail prematurely due to increased pressure of the oil that said it might be a very good choice in an engine with significant wear
Great video Nate. So it looks like STP Synthetic Oil Treatment turns Warren distribution synthetic oil (AKA Amazon Basics, Super Tech, Kirkland Signature, Proline, amd Mag-1 into an oil whos wear protection rivals Amsoil, Schaeffers and Redline! Try comparing Amazon Basics treated with STP Syn Oil Treatment to stock Amsoil XL or Signature.
Probably about right. If I want a thicker oil I will use a thicker oil instead of wasting my money adding a thickener to the oil that provides no benefits.
Can you try BG MOA Extended Formula? I wonder if such oil Additive can be added to a high quality fully synthetic motor oil such as Amsoil Signature Series 5W-30 Synthetic Motor Oil. Amsoil Signature Series is already high in detergents and additives, and I wonder what will hypothetically happen if MOA is added to it.. I need your help to test that or shed some light on it in the comment section.
This test isn’t accurate cause inside modern motors there is not metal to metal contact like this. Tight tolerances but no metal to metal contact. Some modern engines need 0w20 with no added viscosity to flow correctly to critical parts. So in theory. The additive is useless in a modern engine.
interesting test.....wonder if there is much point adding STP oil treatment to already good oil though? i occasionally add it but have no idea if its doing any good ontop of premium/good quality oil
This product clearly changed the viscosity in a major way. This would be similar to running 20w50 in your 0W20 rated engine and that his not recommended at all
Your not supposed to use a thicker w oil in the winter anyways so I believe that this dude probably doesn’t even know how to change oil STP is a great way to protect a old engine

Hey bud I will tell you something to look for these engines rocker arm and pushrods will wear out that might be something to check because if it starts up and rattles for a few seconds then the wear which creates a lot of clearance on the worn rockers and pushrods takes longer for they hydraulic lifters to pump back up they apparently bleed down while not running I had replaced these on a 2000 suburban with 289 thousand miles 5.3 ls
I been using STP for years, oil & octane boost, nothing but excellent results...
In '96 I bought a '94 GMC , 4.3 engine, truck, 55k miles. I used 10w40 and ALWAYS added STP. Around 250-300k miles it was a quart low at the next oil change. I changed to 20w50 Castrol and STP. After 21 years of driving it I sold it with 484k miles on it. I am sold on STP, yes. I have a 2011 GMC now and with these newer engines and their different tolerances I'm not sure whether to add it to my oil or not, so I haven't. But I'm thinking about adding it to my synthetic oil, I'm just not sure.
I'd like to see STP 0w20 vs regular untreated 5w20
Nice. I only put half of the recommended on my cars as I thought it was too thick but after watching this video I'm impressed. I actually didn't even put this in my new tacoma, maybe I should. 🙃
I've been using it since I was 16 my first truck till just today for my jeep and honda ridgeline I live in death valley it was 110 today....I travel up the Sierra Nevadas in winter where its well below zero in I have had no issues ever.
Compare all the different stp oil treatments.
Good video man, keep it up
Thats sounds like a good idea thanks, please keep them coming.
@@NATESINTERACTIVEAUTO Compare Amazon or Super Tech with STP Syn Oil Treatment to Amsoil. Want to see who wins the cold flow akd wear tests!
Overtime or 3000 mile oil changes which is what's that's designed for it will, it would cut the wire down by half plus it has jink and all the stuff the EPA took out of the oil in the 90s which also helped wear any reason it took it out because they claimed it would harm catalytic converters the truth is that might but it will take 20 years for it to harm the catalytic converter in any modern car STP synthetic oil for newer engines with higher clearances company bearings and that's why it's thinner than the Lucas or the traditional blue STP so I've used it for years and not
It seems they got rid of the ZDDP when moving to Synthetic for newer engines, so...What's actually in it? Hard to find direct info apart from marketing speal, VOA analysis would be interesting.
I’m glad there’s people out here like you that do this for our satisfaction, helps DIY type of people know we’re not wasting our hard earned cash.
Well said
it's just one from the best youtube channel i have never seen
STP Synthetic oil additive is an additive, BASICALLY it's a concentrated bottle of the synthetic ingredients found in the oil you buy. There is no comparable differences.
Another video did an analysis on stp, 8 ppm zddp and it increased the TBN with the non synthetic. And ya, 0 is the viscosity of water so 0w20 was intended for no higher than 68F per online viscosity charts. STP for summer uses, MMO for winter.
8 ppm or 800 ppm ?
I might give this a try now that summer is approaching , but definitely NOT during the winter months.
I've used the blue can stp for my moped in three different mc oil grades: 20w50, 20w40 and 10w30. Added in 150km after oil change of each grade and felt them all the same on clutch behavior and actual engine noise more like 10w30 amongst all grades.
You're ABSOLUTELY BRILLIANT! Thanks for the INFO!
I use STP on my Honda civic with 285,000 miles it quiets the engine and reduces oil burning.
It's basically Ester+PAO which has cleaning effect. You don't need to pay for this additives if you simply buy FULLY SYNTHETIC oil in first place which is made of Ester and PAO. Also, true synthetic oils ester and PAO have much lower pour point that normal oils around 30-40 percent. Unless you cool down the oils below -45°C, there won't be any different in the viscosity of both oils.
Most Fully Synthetic are now GTL paraffin or slack wax paraffin or hydroisomerised mineral oil paraffin. The days of "Real" synthetic oil are mostly gone except for a few specialized products like Mobil 1 0W16 or Amsoil Signature.The national advertisers agreed to call oil that performs close to a synthetic "Full Synthetic Motor Oil"
I like this guy i was here in 2.7k subs
And i got nothing but love thank you i will try to improve.
Thanks for your hard work, I liked your video, and w/o critisizing it, I think that this coul be a good series, perhaps adding a thicker version of the same oil (3 tests instead of 2), and testing different brands of additives to try to dettermine the best one. Once you find it, test varios oil brands with and w/o said additive...thanks!
I have thought of testing many oil additives as i tested sTp and Lucas stabilizer. If you have more to add please share.
I use STP high mileage oil treatment plus stop leak and seafoam sometimes both worth great !
thanks for the test and comparison, does this help in oil reduction too?
I read Robert Sikorsky's books "Drive it Forever" and "From Bumper to Bumper" from my library many years ago. He was a member of SAE and wrote a column for the New York Times. his books were compilations of the NYT columns I think. One if the things he said was that the API American Petroleum Institute has NEVER certified any of the well known oil additives, not one of them. He himself I believe approved of Mobil One, and the Teflon additive, I forget the name, but I read those books in the 90's. I think he's still alive but likely too old to be active.
How did you manage to fit the1 quart of Amazon basics + 3 the ounces of the STP in the 1 quart capacity bottle? Surely the 3 extra ounces didn't evaporate. Explain.
I thought I was the only one cought that. real talk subb back thanks
STP is good for lifter tick but I heard it can harm your cat converter
you heard from dbag.. from someone that has been using it for 344k miles and still running. cats are just fine.. dont listen to idiots.
@@mica122213 🙏 🤝 👍
We built a engine in a car & the r&r guy left the drain plug out & the owner drove it 15 miles home & complained about the oil light & clicking so he brought it back it had no oil except what it was built wt stp in the blue bottle! I know it sounds like a lie! But they filled it up & it never did give no problem!
I use stp oil treatment mixed with 10w40 in my 1994 gmc with a mild 350 small block. Truck gets worked hard off road and tows all the time. I feel as though the stp is good for it.
I live along the Equator....I think 5w30 is too thin for my car....[ our climate here ranges from 25deg in mornings to 36deg in afternoons ] ....wil STP thicker oil help increase the viscocity of the oil in my engine?
My 07 Bmw used to eat 1qt/1000miles. i added a bottle of Stp Smoke treatment and the oil consumption decrease to 1qt/5k-6k miles. the additive was pretty thick tho i think thats why
Stp synthetic oil treatment is 300ml wonder if much difference between the slick 50 premium synthetic oil treatment 750ml is any better? Just put stp oil in my 2012 320D touring as bought it with 130k mileage so just wanted to make sure my engine is looked after lol
josephbrown3647, I'm thinking about adding STP in my 2011 GMC Sierra. Can you elaborate on your experience today after one year?
@jimmyworks3600 if I was you look into hot shot secrets. There FR3 or stiction. Both amazing 👏
Good video for those who are scared that it won't be capatable with their car due to the thickness. I believe it glings to the engine parts better than normal oil. I have a 2003 Cadillac CTS and when I put that new Lucas stabilizer for low viscosity, the car felt so much quieter. Not a placebo neither. I kept noticing it and noticing it. I'm like yo this car feels smooth right now. Not that it wasn't smooth already. But I definitely felt smoother. The car sounds like it's not even on. Also I noticed my acceleration had more power. Trust me. That New Lucas in the 12oz bottle is some good stuff. I was surprised. Note* what I did was do an oil change with STP high mileage synthetic & I used a Lucas Low Viscosity Stabilizer when I changed the oil. I do my oil changes every 2+3 months. Somtimes every month just to be safe. Oils cheap. Engine ain't. So when I tried the Lucas, it felt like a really good oil change. Trust me.
Do you work for Exxon Mobile ?.
Have you ever done any testimg with 0w 20 STP motor oil OR Havoline 0w 20 lifelong?
Hi,
Is it safe to use stp in
Nissan qashqai 1.2 petrol turbo engine ,
If yes, which one would you recommend?
Regards
It was a pretty awesome video. I'm sold on the product. But this particular product is not available in India. How about the regular oil treatment (blue colour)? Any chance you could do a test on that please?
I already have that and yes it is very similar. But i plan to test it more. I had tested it personally in the past.
Very nice video man! Congratulations and thank you very much! I will always use STP since this moment.
car : 2001 mercury grand marquise
i just added this product ( LOOVE it)
in kuwait its 54 celsius in some areas in 2pm these days summer and when i heat soak the engine (drive in traffic , accelerate hard and stop hard and do it again) the the valve trains begins to dance and jiggle (oil thins out so quickly ) i hate the new factory recommended motorcraft 5w-20 full synth
with this product added engine sounds new now matter how hard i push the engine
the new oil ford recommended is good only for winter
add it gradually and slowly after it reaches operating temperature while the engine is running idle
I’d run 5W-30 at those temps lol
Appreciate the video. Like most, I have been using STP products for many years. Validates what I thought.
I read once that STP throws off the balance of additives that are already in the oil. It's like putting four eggs in a cake recipe that calls for two.
Ive never used any type of additive with my oil changes, justmake sure to change them every 3k miles. I bought the car with 17k miles and now it's about to hit 77k, should I add some of these additives?
Please tell me: During the lubricity test, did the STP blend generate a lot of air bubbles? It is a major cause of oxidation and cavitation....was the STP blend foaming or bubbling?
I could not see any air bubbles or cavitation on the test.....so I'd say no.
I’ve only had one experience with stp 10w40 in my 79 gs1000 motorcycle. I always used Valoline but the store close to me only had that weight in stp and penzoil. I chose the stp and after one ride my bike was leaking badly from places it barely seeped from before. Not saying it’s a horrible oil but my advice is to stick to one brand because other brands contain different additives and chemicals that can cause weird stuff to happen to your seals.
My engine is starting to knock... hasn't been ran but a few minutes total since the slight knock started randomly one day... I about to add some of this to my engine. It's only 4 buck. And the engine is otw out already so might aswell.
How many miles on your engine?
@@johnfranklin5277 less that 200k. 5.3 vortec
I have a 2020 Honda Civic Sport Touring. I read the manual for the car and it says that no additives are needed for the car's engine. However, i've also read comments from other people where they've mentiomed that they've used additives on their cars about as new as mine including Hondas, and they were VVVERY satisfied with the results. Anyone care to weigh in...?
STP requires a larger starter motor to turn over engine in cold weather.
Not true, it got down to 43 deg f here in Southern California one night in January, and the car started just fine! 😊
Can you use this in a turbo charged car like the -22 Honda accord?
S T P was designed for hard driving s t p stands for stop Tim please s t p ❤
Thanks for the post as always
Good video,
I've never used STP but have heard good things...
Imo no need for STP if the oil your using has good chemistry and has high enough zinc levels already in the oil like 1100 ppm and above as long as you don't have a catalytic converter on your vehicle as the high zinc can clog the cat that's why they have lowered zinc level in the newer oils with SN Api specs.
In vehicles and equipment with no cats this definitely could help if the oil your using doesn't have high Zinc levels already.....
Only other concern would be COMPATABILITY of the motor oil and the STP components, I prefer to use a top quality motor oil like Amsoil ZROD with HIGH ZINC already in it so there is no problems with compatability of all the ingredients of the two products being mixed.....
its not that surprising since the oil you used was very low viscosity i am very sure though that if you used that stp on an engine requiring 0w20 it would do more harm than good since most of these engines have variable valve timing or/and hidraulic valve lifters plus there is a small chance that if the oil filter is small or of bad quality it would fail prematurely due to increased pressure of the oil that said it might be a very good choice in an engine with significant wear
Well done test! Would you be willing to repeat the test with synthetic-blend and full-synthetic oils?
Great video Nate. So it looks like STP Synthetic Oil Treatment turns Warren distribution synthetic oil (AKA Amazon Basics, Super Tech, Kirkland Signature, Proline, amd Mag-1 into an oil whos wear protection rivals Amsoil, Schaeffers and Redline! Try comparing Amazon Basics treated with STP Syn Oil Treatment to stock Amsoil XL or Signature.
Thank you for such a good test
How about for boxer engines?
Amazing science here ty for this test. STP is better used with than without imho.
Stp additive convert 0w20 to 10w40 motor oil
Probably about right. If I want a thicker oil I will use a thicker oil instead of wasting my money adding a thickener to the oil that provides no benefits.
@@averyalexander2303 stp seems to be lucas oil stabilizer, and lucas has good critiques
@@marcianoterricola very true there are benefits, have you tried sTp?
@@NATESINTERACTIVEAUTO No, but it must be good, but everything in life when you add up to one thing takes away from another
My dad bought a $100 of lucas products off of a sales man back in the 90s including stabilizer, power steering stop leak, etc. Still got half of it.
Ok Nate
I like your common sense I just subscribed to your Channel
Joe... Navy veteran ACU-2..
Thanks for the kindness and the NIA community is about sharing your experience and knowledge even if it doesn't agree with me.
I trust stp from 2012 to 2021 products are amazing also oil filters are the best
Useful information. Excellent & Thank you
Can you try BG MOA Extended Formula?
I wonder if such oil Additive can be added to a high quality fully synthetic motor oil such as Amsoil Signature Series 5W-30 Synthetic Motor Oil.
Amsoil Signature Series is already high in detergents and additives, and I wonder what will hypothetically happen if MOA is added to it.. I need your help to test that or shed some light on it in the comment section.
Absolutely 💯 percent agreed. Keep the suggestions and questions coming
I agree. Test the MOA.
This test isn’t accurate cause inside modern motors there is not metal to metal contact like this. Tight tolerances but no metal to metal contact. Some modern engines need 0w20 with no added viscosity to flow correctly to critical parts. So in theory. The additive is useless in a modern engine.
the point was to show the ability to prevent wear and reduce friction, period.
nice work, appreciate the video, well done
interesting test.....wonder if there is much point adding STP oil treatment to already good oil though? i occasionally add it but have no idea if its doing any good ontop of premium/good quality oil
i did not see u mix and stirr the additive.
Awsome video. Now I will know what to use.
You lost me I thought the bottle on the right was oil and 3 Oz stp you seem to be adding Straight oil to the mix maybe I missed something
half the stp is still in the measuring cup.
Play vid speed at 1.25
I’m playing it at 2 times.
i think you need a bigger funnel.
but thanks for the vid.
I do agree in cold temperatures
This product clearly changed the viscosity in a major way. This would be similar to running 20w50 in your 0W20 rated engine and that his not recommended at all
Don't cheap out on oil if you plan to keep your vehicle for a long time.
It is proven engine oil treatment will increase your engine oil viscosity and will cost worse oil flow during cold startup.
Your not supposed to use a thicker w oil in the winter anyways so I believe that this dude probably doesn’t even know how to change oil STP is a great way to protect a old engine
