Thanks for posting. I run penrite racing 10w40 In my evo. We’ve probably been to the same track days over the last couple of years (Melb). I was considering trying Nulon racing 5w40. Where are you getting your oil analysis done?

Interesting thanks for the info. Were UOA's done to verify the viscosity?

Thanks for the reply. Is it possible to say if the oil looks like a good candidate based on that info or is is still dice-roll and UOA time? My application is a street/fun driven BMW with a 3L twin turbo straight 6 making ~166HP/L with oil temps around 120-130*C (248-266*F) at full noise.

Hi all, I have a question regarding Penrite's 10 Tenths Racing line of oils. It's an Australian company so you might not be familiar with them but they claim to have a very stout high performance gasoline engine/racing style oil line. Their additive pack is very strong with antiwear...

For engine oil, I was put off by the 335i thread on here where the take home message was "if you have a BMW N54 engine it cooks oil and you will destroy the best synthetics in around 1000km". You can understand why cost may be an issue when facing such a ridiculous OCI. Turns out the thread is...

I emailed redline and said my vehicle actually calls for MTF-LT-5. This surprised them as they thought every N54 equipped vehicle used only MTF-LT-3. Not the 1M, it seems. In light of this they revised their recommendation to their DCTF fluid...

They don't recommend it themselves. Punch my car in and it says D6. Most use D4 but that said, redline themselves say MTL provides better wear protection, so it appears to be a choice between cold shift smoothness and wear protection. I'd like to hear from people who have used either fluid in a...

The specs of redline D4 ATF quite closely approximate stock fluid in terms of viscosity but I have no data in terms of additive pack. Almost everyone uses D4, redline's site says D6, and MTL is used by bmw engine and gearbox builders alike. I'm leaning towards the MTL myself.

Ok, weird I cannot edit that post. I'll just add this here from Redline's manual trans lubes PDF found here http://www.redlineoil.com/content/files/tech/Man%20Trans%20Lubes%2010-13-1.pdf Quote: D4 ATF and High-Temp ATF provides the gear protection of a GL-4 gear oil in an automatic transmission...

Great discussion here, very good reading Originally Posted By: SLO_Town Originally Posted By: oilnub I do also plan to swap out the thermostat so as to decrease the cruise/normal oil temp to ~93*c from ~115*c .... Your engine has a BMW specific thermostat and housing. Not sure if what you...

Its weird, 0w-40 Castrol seems a little old school now, no molybdenum at all? That said it's $75 vs $99 for M1 0w-40 for a 5L bottle... Hard call!

All very valid points guys thanks for your input. I know the thread I was referencing is super old but I couldn't find anything more current so I had to ask the question. I'll leave the oil temp alone for now, use M10w 0w-40 or Castrol 0w-40, run it for a couple thousand km and do a UOA. Got...
