What oil?

[r4dr]

I think Motul works well because it was designed well. LMP1 and LMP2 cars use Motul for a reason.

Are they a sponsor? Because that would be my pick for the reason.

Castrol 10w60 was clearly the favorite, but the real question is if you wanted take advantage of FCPEuro's deal and had to chose between BMW 10w60 and LM 10w60, which way do you go?

I use the BMW 10w60 from FCP. my last oil change, including filters and gaskets net cost was $17.

Marketing rubbish??? What the heck would it matter if it was 4v or 3v or 2v without VVT?

vvt often requires higher viscosity to have adequate response time. I simply mentioned 4v it because it seems like a lot of people think the oil knows whether it’s in a bmw or domestic engine

I'll be trying Motul X-Power this weekend after using up my stock of Castrol TWS. I've been happy with Motul in my STI, though that's 5W40.

Le Mans is next weekend and it's going to be awesome!

Personally I wouldn't choose oil by what racing teams use. That oil is changed frequently, for LMP cars usually between races. A formulation that works well for race cars for one weekend is very different than one that lasts 7500 miles.

Dont get me wrong Motul is a quality oil. But looking at the logos on the side of racing cars is not what you should be concerned with.

Currently have a stockpile of Castrol edge that I'm going through. After that going to try either Ravenol or Motul.

I bring some leftover liquimoly to the track in case I need to top off oil, I never use it for a full fill.

btw Driven make a 5W-50 synthetic "street " oil which was meant for 4V variable valve timing engines so cant see why it wouldnt work as good as any other oil all the fan boys go nuts over

the fact they even recomended a 5W-30 and then changed to 10W-60 which is not a small change shows their visocity recomendations have zero credibility.

What do you guys think of the latest (2013) oil bulletin from BMW on our engines?- it says a specific Castrol 5w30 is approved along with TWS

IIRC BMW pulled that soon after posting it and went back to recommending 10W-60 oil (TWS, then TwinPower Turbo). People think it's current because the threads are still floating around with their original titles ("5W-30 now allowed!" etc.) but it hasn't been for years.

[IamFODI]

Yeah, that's what I meant as somewhere, something is getting hotter if that's the case but ultimately that means the oil has to get hotter too (and since the heat transfer in this example is poor it also means it stays hotter longer and ultimately, over time, the oil will get hotter and hotter if it cant get rid of ththeheat it is exposed to)

This is what would happen if the oil were the engine's main or only means of heat rejection.

Aside from the exhaust, the engine rejects heat through the coolant, the oil, and the air (pretty sure in that order). Reducing the proportion of heat pulled away by one of those will increase the proportion pulled away by the others until one or both reach capacity.

Arith2 said his lower oil temps were when he was just cruising around. In those cases, the coolant system is WAY below capacity and should easily be able to pick up any slack.

Excellent! Thanks. I always use PP, just did not think of using their return shipping. Thanks again.

I think BMW doesn't give a damn about a 20 year old platform and never really knew why the bearings failed in the first place lol.

[Carbonvert]

Up to $30 each time right? Not $30 total per year. That would only cover 2 boxes, though that's better than nothing.

I am reading it as $30 per shipment up to 12x per year. It looks like you must activate this feature.

I attached both the 2013 (TWS and 5w30) and 2008 (TWS only) bulletins to this post. I ask because I see Motul 300v 5w-40 is on FCP. Always wanted to try that in my street driven car.
