I run Total Quartz Racing 10W50. I seem to run all of that oddball stuff nobody else runs.

Because I'm not doing an extended drain interval anyways. The oil will get changed every 2000-3000 miles because much of it will be on track.

Wasn't that the M56?

I'm even more confused because even Bimmerworld doesn't have a normal M54B30 listed... they only show the M54TUB30

Because that adds up very quickly?

So the consensus is 5W-40?

Is that also a recommended grade and weight by BMW. I doubt it matters. I have 2 more HPDE events as well as a few autox thrown in between. I'll likely change my oil after the summer season is over.

The relatively new Pennzoil Ultra Euro 5W-40 makes some interesting claims. I would give this a try if I didn't stocked up on the BMW oil already. I've got three change worth before I can give the Pennzoil a try.

If anyone is interested in pursuing this further.
Here's the Pennzoil datasheet: http://www.pennzoil.com/documents/PE...ropean5W40.pdf

We (BimmerWorld) often choose to go with a lower viscosity on our racecars with Red Line and we can get away with it because it does have better lubricating properties than many of the other oils in the market. Additionally, the ZDDP package prevents wear, and it has excellent anti-foam and compressibility characteristics that work well with the dual vanos engines.

For most cars, we recommend a slightly higher weight for track use. In that environment, the temps are higher and especially on a hydraulic lifter engine, you usually need the extra viscosity to keep the lifters pumped up. For the M54 on our chart, it is a 5W40. In our racecars, we have been using mostly a straight 40WT in both the M54 and N52 which is similar but requires that we warm the engine up.
I just bought 40wt from you guys for an upcoming track day next Saturday, should be around 98... straight 40wt only makes sense. Warming it up shouldn't be an issue!
