Unless you do a full boost pull into your driveway, letting the car idle for 1 minute is useless. I run a Oil cooled only turbo and the most I let it idle for at shutdown is 30 seconds.

The only thing that shows up is on the 328, which has a "fully controlled oil pump" but is still mechanical.
I'm no expert, but it looks pretty mechanical to me...

After a really hard run, eg at the track (not a drag strip), I will spray the oil cooler with a mist of water to instantly cool down the oil. I don't like 260-290 degree oil sitting on my engine components. Sorry, I'm old fashioned like that.

With misting, I've gotten oil temps to drop 20 degrees in a matter of minutes. Sublimation is a wonderful thing.
Technically that is just a phase change, sublimation involves going from a solid directly to a gas, ie dry ice.

Looks like a timing gear to me (im not an expert just saying what it looks like)

however about the electric oil pump... remember the posts about people doing oil changes and their key's were in the car... they removed the bolt and black gold shot out everywhere. this tells me there is some electric oil pump somewhere.

You're right. I was getting a little excited and skipped a phase.

yeah, but if you follow the link the image is labelled "LUBRICATION SYSTEM/OIL PUMP DRIVE". I haven't been able to find any documentation about an electrical pump, primary or secondary, but I haven't dug too hard.

The picture posted above is the drive system for the mechanical oil pump on the 335.

Notice I said "coking" not "degradation" being an issue. Coking is a term that refers to the conversion of the crude oil base in engine oil into lighter oil-based products, like kerosene, naphtha, etc which obviously don't have the lubricating properties the engine requires. My point was that 100% synthetic wouldn't break down that way. It may break down in different ways, but I don't know what those byproducts are. And correct me if I'm wrong, but 100% synthetic does not use a crude base, like some of the old synthetics did.

Lets think about this electric oil pump thing for a second. Why would this electric oil pump come on during removal of the drain plug and pump oil out of/towards the drain plug???

BTW: The NG6 motors DO NOT come with electric oil pumps. The only BMWs that I can think of with electric engine oil pumps are M cars that use the pumps for supplying the main ENGINE DRIVEN oil pumps with additional oil during cornering. And I'm currently looking at information on this. The only cool thing about the NG6 oil pumps are that they are volume-flow-regulated.

The BMW spec oil is actually petroleum based.

I'm actually surprised to hear that. I thought all newer generation synthetics used 100% synthetics, base and all. Interesting...

Of course they have the same tech. BMW uses Mitsu turbos, Subaru uses IHI turbos which are possibly the best built turbo period.

Here's a quote for ya. You can lookup the data yourself on google.

________

The Factory BMW Synth 5w-30 is a version of Castrol TXT Softect sold overseas. A few important things about the BMW oil a) it is a Group III hydrocracked oil which cannot be called synthetic in Europe, b) it is a heavy 30 weight (30 weight can run from 9.3-12.5cst@100c, the BMW oil is about 12.2cst), c) it is a ACEA A3 oil which means that it is approved for longer change intervals and has a HTHS (High Tempurature High Shear) measured at 150c of greater than 3.5.

Thanks for finding that lefcoastman. I wonder if they chose that particular oil because it is better for break-in than full syn (is it used for oil changes in the US?), or because it is cheaper than fully synthetic (according to European standards), or some other reason.

Thanks for the information! I always wondered why there wasn't a LL-01 rating on them. We use to use/sell the BMW oil but this year switched to ELF Synthetic engine oil.

Hey Jon, any idea if the ELF is 100% honest-to-god full synthetic?

It's a full premium synthetic oil imported from Europe. They sell oil that meets BMWs requirements. http://www.elfmoto.us/lub/lubusa.nsf...?OpenDocument&

Downside is that ELF can be hard to get and at times can be expensive. I sell them for $6.50 a liter. Not quarts.. liters.

In my opinion if you can find a LL-01 or LL-04 then I recommend using it.
These Mobil 1 0w-40, Valvoline 5w-40 Synpower, and Castrol 0w-30. For the Castrol 0w-30 make sure the bottle says it's made in Germany.
Another brand is Amsoil European Car Formula 5w-40.

Mobil is true Group IV synthetic. Valvoline is hydrocracked Group III.
