Looking to see what oil everyone is running in their tuned 335is. Ive been jus using the BMW Synthetic 5W30. Is it ok to use the oil for the M// cars or use a little thicker blend in the summer. Please state what brand you guys are using and any advice on which one.

[ajrettke]

I use mobil1 0-40 and also used it with my older S4 (2.7 TT engine).

[XPO186]

I've got Elf Solaris 5W30 in the car right now... but I'm going to Motul 300V 5W40 for the summer months

[luca335i]

Would the thicker oil be harmful or clog any engine components

[Rugs]

I use the BMW Synthetic 5W30.

[Sniz]

was using Mobil 0w40 for 40k miles just about all tuned since 4k miles. No issues.

The oil cap actually has Castrol imprinted on it ........
since I change oil every 7500K; I use Royal Purple for the in between OC.

Redline as well dependant on availability.

If you can afford $10.50 plus per quart then I prefer Redline ....

No.

Heavier oil may not provide sufficient lubrication and heat transfer. More isn't necessarly better. Plus your gas mileage may suffer.

Stick with BMW branded Castrol 5w-30 or Mobil One 0w-40.

I have just gone from Martini to Royal Purple which I believe is superior. Will test oil at next interval (5,000K for me).

Take care with the viscosity as I once seized a g/box due to the oil being a tad too thick.

The manufacturer's standard is LL01, which the Mobil 1 5W-30 sold in the United States does not meet. There is a version sold in Europe that does (Mobil 1 5W-30 ESP), which confuses the matter.

The correct Mobil 1 in the United States is the 0W-40.

All oils that have met BMW's standards will have LL01 or LL04 in small print on the back of the bottle.

I would stick to this list. Personally I choose to run Lubro Moly 5W-30...used and endorsed by BMW dealers in Europe (changed every 7500 mi.) You Can buy it at Bavarian Autosport. Been working out great for me.

The new BMW list should put this issue to bed, but there is one "gotcha" on it. The Valvoline SynPower 5W-30 with BMW approval is the MST version, which is NOT what is sold at the retail level in North America. It also my understanding, which may be wrong, that Valvoline SynPower 5W-30 MST is only available in bulk.

motul works great

+1...the Mobil 1 has a "European" Spec printed on it. That's the one to get.

Exactly, same goes for Castrol. It's the Made in Germany or GC 0W-30.

That would be the 0W-30. The Castrol Syntec 5W-30 sold in North America has no BMW approvals. On the other hand the 0W-30 has pretty much everthing; BMW, MB, VW and on and on.

mobil 1 0w-40 FTW

[chowser51]

Just picked up some Mobil 1 0w-40 today. Advance Auto was having a sale, 5 qts of any Mobil 1 and a Mobil 1 oil filter for $29.99. I ended up getting two sets, but Mobil 1 doesn't have an oil filter for my BMW, so I got filters for my wife's car. I'll pick up some BMW oil filters when I'm ready to change.
