OK I got my 2nd UOE and aside from lower silicon which I expected after breakin I was suprised by lower metals as well. Although the car saw less dyno runs, it saw many more track days than the first sample.

So it seems like Mobile1 TDT 5w40 is performing slightly better than Motul 8100 5w40? Comments? Opinions?

 

That corresponds to what Resolute said in this thread:

i burn less oil with mobil 1 0w40 than motol 10w30 300v and have been running it for the last 10k miles with no regrets. no oil analysis but i recommend it and its half the price

 

Rotella sythetic has my vote!

 

I run Mobile 1 15-50w Performance Oil.
