[@DimoS...]

i agree my friend james is right. I have a corolla tsport (2zzge engine 192hp 1.800cc and 8,350rpm) and some people had a problem with intake camshaft wear, Toyota recommends 5w30 oil, but the most people, like me, use 5w40 or 5w50, I use liqui moly molygen 5w40 because it also has anti-friction, what do you recommend for this engine if you want to tell me? the use is not on a track and extreme temperatures continuously but I often reach 8,350rpm.

[@joshwatton9335]

Could listen to Jay talk all day.

[@LubricationExplained]

This explanation is fantastic. Just keep in mind what you’re trying to achieve. If max horsepower is your main concern go for a lighter viscosity, but just be mindful that everything will wear much faster. High ZDDP isn’t the be all and end all - it’s great for protecting cams and gears, but comes at the cost of increased friction as the surface roughness of an anti wear film is higher than machined surfaces. One other thing - racing oils tend to be some of the few oils that are still truly 100% synthetic. PAO molecules have lower traction coefficients than even the most highly refined Group 3 mineral oils, helping to lower the internal friction. Also, not all PAOs are equal! mPAO has lower traction than cPAO!

[@realstreetperformance]

Yeah great video, very informative.i'm running a 2.0 tfsi vag turbo engine with stock clearances but with stronger valvesprings, the engine is running around double the horsepower on a hybrid turbo setup, on 5w30 i am thinking of switching to 5w40 which is still a stock viscosity for my engine, it's just switching from longlife to regular synthetic, so i think i will be good, never had any issues on the 5w30 but on cold start the valvetrain makes a bit of noise, not much but i rather be safe than sorry sonce i am running a rather expensive stage 1 cnc ported cilinderhead wich i don't want to brick in the long run, and also my high pressure fuel pump is driven off the camshaft so my best bet is up the viscosity for that longevity.👍

In my race engine 2.2L f20b I run Motul 300v 5w40 ester. I used to run Amsoil z-rod 10w30 high zinc race oil but it kept breaking down after a session of track usage. The 300v of what I seen so far resist alot against e85 and it lasted me for afew tracks days before changing. I do have also a infinite oil filter and I always open it and check for particulates. Best oil I've seen in over 20 years. Motul is my #1 for me.

How have you been verifying the oil is breaking down? How do you know when its done?

@@BEANS-O-MATICtransmissions I run e85 or M1 in my race engine. Because of my ring gap @.022" top ring and .024" secondary ring i do get alot of blow by. I check my oil at a local lab that tests all types of oil. They told me because if the fueling I'm running the base oil Amsoil is breaking down faster vs the Motul. The base oil property in Amsoil is what breaks done the fastest not the additives. So I was replacing my engine oil almost every track event. With motul I replace my oil every 1500 miles or so. Depending on how hard and hot was the day and driving.

[@ZillaFullBoost]

Good video. My Red sport calls out for 0w20, but we find that these VR30’s tend to burn some oil quite a bit. After some Blackstone lab analysis the viscosity is far from 0w20. I’ve now chosen to use 0w30 for the same cold start protection and the 30 weight helps with the viscosity break down especially with the heat here in Florida and the abuse my FBO engine gets at the track.

[@realstreetperformance]

[@veiri86]

Thanks a lot for the heaps of knowledge. The million dollars question is, if am on stock block and stock clearances and fully built head, and my engine is running 600whp boosted compared to 200whp NA, so should I keep using stock oil? Am talking about boosted F22C and 4b11T. Thanks again Jay

[@qleap99]

According to what he said, with stock clearances you should follow the oem oil recommendation. Engineering Explained did a video which concluded this as well.

[@calawaydp]

Solid question: The oil weight explanation makes complete sense to me... So why do some aftermarket parts manufacturers recommend heavier weights on OE bearings if you have certain upgrades? Example, I have a 2020 F150 with a 2.9 Whipple. Only internal upgrade is billet oil pump gears... OE oil weight is 5w20, Whipple recommends going to 5w50... any insight?

Hello Jay, i was wondering if i could get your opinion. I've a 2013 fiesta st 1.6 ecoboost with 140k kms, i always runned the 5w20 that the manufacter recomended, but i live in portugal where temperatures are considerabily higher than germany or england where this cars were mostly sold. I had induction kit, stage 2 intercooler, decat, exast and a 240bhp map. I used to run that car a lot fast. One day there was like 34°C and i broke it. Crankshaft got scratched, had to make full engine rebuild. Added bafled sump, new forged pistons (0.5mm larger) and rods, new crankshaft, worked engine head, king bearing and etc. I'm about to mount it on the car and i'm think of running a 5w30 motul specific with break-in additive for like 2000km and later switch to motul 300v 5w40 (wich my fiesta st coellegues use on theirs when they do trackdays.

Thank you for your wisdom, I do have a question though. Say for example a stock boosted eco engine is using 0-20 oil, but is now full bolt on making over 120+ horsepower from stock, and is taken to track events. Would it be wise to up the weight? I feel like even though you're stating to follow OEM guidelines, 0-20 would thin out wayyyy too easy on a tuned boosted production engine.

Im new to JZ ownership, and was considering Valvoline VR1 for the high ZDDP. Would you make a vid more in depth about ZDDP & why more is not always better??

[@realstreetperformance]

Sure. Will do

[@LubricationExplained]

Short answer - the “P” in ZDDP (Phosphorous) poisons catalysts, which is why standard engine oils have been steadily reducing the amount of ZDDP in formulations. It’s mainly an emissions regulation thing. Secondly, ZDDP forms a sacrificial anti wear film on metal surfaces, but the film isn’t uniform and higher surface roughness than a typical machined surface. As a result, too much ZDDP can increase friction of internal sliding surfaces within the engine.

[@ryanlowe3588]

Is there a place we can go to put our engine and it’s house power to find out what we should use... coz now I’m not sure I’m using the right oil... I’m using castrol edge 15-30

[@BeltecPerformance]

Wont thicker oil affect the cam journals seeing how those clearances stay tight?

[@adamdodsy84]

What's your opinion on changing oil weights based on intended car usage? I only ask because I'm sure coyote mustangs change from 5w20 to 5w50 if you opt for the "track pack" with no internal engine changes that I'm aware of.

[@realstreetperformance]

Intended usage does matter. It’s a scary decision for OEM’s to start out with a thicker oil because the car may go to a cold climate where the owner doesn’t let the engine warm up before driving off and could result in a lot of warranty engine replacements

[@street_fighter_mx5]

I just built an engine they runs strong but the rings didn’t seat. I was going to use thicker oil before I dissemble it. What are your thoughts ?
