What’s the best oil for tuned and highly boosted N54 engines?

[Jeffman]

Starting a new thread to avoid yet another thread jacking in response to another Spoolstreeter’s question about oil. I’m sure this has been discussed before, but hey, motor oil technology does improve over time, no?

Here is the previous question and my reply in the new FCPEuro thread:

While all this FCP euro warranty and oil is 100% off topic. For someone who only needs to do 1 oil change a year and does not paying $$$. What oil should I be using? I don't mind 1 'expensive' oil change a year.

Take a look at that Project Farm video on oil testing someone else posted the other day (linked below for your convenience). Looks like Amsoil, Redline and Pennzoil are top performers. It would be good to know which of these would be “best” for our highly boosted and modded N54 / N55 engines. I don’t mean to cause another thread jacking so, I’ll also start another thread, LOL

Pennzoil Platinum Euro 5W-40. I just got my result back from blackstone.

E50, maxed out stock turbos.

 

[hellokitty]

Oh, and for comparison, the prior two UOAs on my report were on Redline 5W-30. Pennzoil wear numbers are much better than redline to my surprise.

Nice! Thanks for sharing your data. Do you use the stock oil filter? Also what’s your rationale for using 5W-40 over a 5W-30?

Redline is a pretty thick oil and their 30 weight runs close to other brands’ 40 weights.

The 40 weight generally has better specs compared to 30 weight such as HTHS, NOACK, etc. Pennzoil does not make a LL-01 30 weight so I use the 40.

Mobil 1 euro 0-40
I've put over 100,000 on the stuff at 20psi +. And a fair estimate is 10,000 of those miles under a racing/abuse situation (drag, HPDE, street, ice racing).

Does anyone have a Blackstone report for the Castrol 0w-40 Euro blend ?

 

[GotPwned]

Heres a Blackstone report for a 5w-40 Liqui Moly. Car has FBO, Pure Stage 2s, inlets, and is running E50 on a custom tune pushing about 22 psi boost. The car had 96k miles with oil change intervals at around 5k miles.

Which blend of liqui moly?

leichtlauf high tech, I have switched to molygen 5w40 since then and will update on my next oil change

Thanks for the info. Now only if FCPEuro carried it!

I've been running Motul X-Cess 5W-40 and a Mann filter for probably 50K miles while I was FBO on the OEM twin turbos, and another 50K after going single turbo (made the switch to a ST around 100,000 miles). I'm currently at 147,000 miles. I change the oil every 3,000-4,500 miles.

I've always gotten back great Blackstone results and don't see any reason to change.

I live in FL and I dont have an oil cooler and my oil temps stay between 210 and 220 about 85% of the time and move up to a max of 240 when I'm in light traffic, if its heavy and I'm idling alot then the highest I've ever seen was about 245/250. The oil cools and protects the engine very well with little to no oil loss between changes.

Nice. Your oil looks amazingly clean!
(Are you sure your doing the test right? You know, you’re supposed to take the oil sample out from the bottom of the engine, not from the container before you pour it in haha ).

What he said ^^^ good stuff.

Is this what you're referring to?

Definitely cheaper than what I'm using now. Might give it a try next oil change.

And Schaeffer’s tested nicely according to Farm Project. At $8.21/qt Schaeffer’s Supreme 9000 definitely looks to be a good value compared to the top-rated Amsoil Signature Series that costs over $18/qt for a case of 12 on Amazon.

Looks like a completely bullshit oil scoreboard made by Amsoil. Blackstone or nothing for me
