Oil for B58 Ineos Grenadier

[edyvw]

Is it common for new engines like this b58 to make oil when new? I did a 5100 mile UOA and had 3% dilution. Just changed oil today for a trip to Moab will change when I get back.

Hmm no. 3% is fairly high for BMW DI engines. I'm not sure whether it has anything to do with specific tunning for Ineos.

From your knowledge is there a point at where this is a warranty related issue?

I think it is too low for leaky injector.
How long did you run engine before taking sample?

The engine had 6209 miles total. If you mean in the driveway, maybe 5min to warm it up good. Oil had 5100 miles total.

That might be your culprit. You have to get the oil to the operating temperature, then drive it 10-15min at that temperature. I usually do a sample after driving it for at least 30 minutes. You want all contaminants to evaporate.

Watching oil temps recently surprised me. Oil didn't get hot until the car was running over 70 mph for about 10 minutes...this was AFTER the engine was "warm". Starting a cold engine and running it 5 minutes is not sufficient.
