Tell us please composition of CBU? What makes CBU?

Do not speak in plural, and do not ask me questions, ask yourself why some petrol engines & diesel (egr off) engines (even after a million kilometers), do not accumulate CBU, I explained it to you but you still do not understand or do not want to understand, because in this way all those who read the thread would know that you know a lot of theory and 0 practice.

I know it's painful when all your life you thought that the accumulation of CBU depends on oil and after so many years a stranger has destroyed your theory.

No acrimony bro

So, you actually have no idea. You could just just say that.

I like your answers when you get stuck and don't know what to answer because you don't really know anything about CBU stacking.

Sure. Just say you don't know or don't answer at all.
You are not helping anyone.

I've shown you all about CBU stacking in another thread, and you're still talking nonsense....

It is ok if you don't understand.
We all have limits.

Edy,

I've been using Motul Sport 5W40 per your recommendation for the past 6k miles since April 2022. Thats street driving plus 12 track days.
I used to do one oil change per year using OEM 0 or 10w30 along with about 6 to 8 track days.

Will I be okay running 5W40 with limited street usage, <1k miles, for the next 4 months through the northeast winter?Morning lows of 20s to 30F. If its a big no-no I wont do it and will get the oil change, but I'd like to follow my old schedule and not have to do an additional oil change for the few winter months where I hardly drive the car.

Yeah, absolutely.
Sport is API approved oil, so there are oxidation limits.

Which is better redline 5-40 or motil sport 5-40.

Tough question. Perhaps impossible to answer.
Both are very good. Redline claims it "meets" specifications of BMW LL01 etc. but I am not sure how considering such high HTHS etc.
I think generally you can't make mistake with either. They are both geared for track use. Motul is bit thinner with still high HTHS so it would have less drag on engine and allow turbo to spool bit faster.
Again, basic rule of lubrication: as thin as possible, as thick as necessary!

I personally would try both and see which you like best.

Thanks for this thread, especially edycol and kitty (sidekick?).

I feel kinda dumb for swapping out PPE 5w40 for TPT 0w30 for winter.

I'll be sure to swap it back when I get the E85 tune on in the spring as I have some jugs left over.

Happy Thanksgiving!

I wouldn't sweat it. PP Euro 5w-40 and BMW 0w-30 are formulated very similarly and both carry LL-01/LL-01FE. Both use Shell GTL base stocks, which is very robust. I'd keep the 0w-30 in there for the winter and switch to 5w-40 when things warm up again.

On North American market TPT is made by Castrol since 02/2021.
There is substantial difference between TPT 0W30 and PPE 5W40. PPE has really strong HTHS at 3.88mpas. TPT being Castrol is probably around 3.
It is also very light for XW40 oil at 12.8cst so, it will do good in winter.
If cold start is an issue and average ambient temperatures are really low, 0W30 LL01 FE is better option.

Interesting… thanks for letting me know about the switchover to Castrol.

Is GTL being used anywhere else besides shell, pennzoil and Quaker state?

Mobil1 is using it too.

At what temperature or conditions does HTHS become a significant factor for reducing wear? Is it mainly for keeping an oil in grade and oil pressure up during sustained high load/RPM?

HTHS is measured at 150c. It plays role in everyday driving. It is resistance of oil to temporary or permanent loss of viscosity.
That temperature is common around piston rings, journal bearings. So, it is very important. Once HTHS is not sufficient, ZDDP is last defense against engine damage.
Too high of HTHS is also not good unless engine is made with oil like that in mind. It is not going to damage anything, but it will be drag on performance.

Just picked up the Castrol 0W40 and see the Porsche approval.

Is there a certain oil we should be using if on full E85, or does it not matter?

Using LiquiMoly 5w30 right now and have no complaints, but wondering if there is a better option out there for E85 use

I would use a 5W-40 and change the oil twice as often (4-5k) for street use.

I run Motul Xcess Gen 2.

Avoid oils with high ester content for the street like 300V or Redline as it will oxidize rather quickly.

If you need a 5w-30 and don’t drive like a manic regularly, run Motul Specific LL-01FE. Starting TBN is very strong at 11.1, which should hold up great against oxidation.

No track use, but do a good amount of roll racing, nothing crazy. Right now my OCI is at 5K, but was wondering if it was necessary to do it sooner around the 3K mark if there is fuel dilution with E85 that you guys know about that would effect certain oils.

Will switch over to X-Cess next change if this is what you recommend, unless there is another you recommend that’s more $ friendly (I know Edge and PP Euro formulas are favorited on here I see, just more concerned about the E85 aspect that would cover all basis).

I don’t necessarily care about the oil weight, just want to know which would be better for my application. Living in SoCal so “cold” isn’t the biggest factor lol.

Thank you
