Since doing that, in addition to the engine running noticeably better, it uses virtually no oil between changes and produces almost zero soot. Really satisfied with the change. The car has never run better.



Driven BR30 used as a transition over to Motul 8100 X-Cess Gen 2 5W40...
I think I'm going to do this. Any reason why you chose BR30 vs BR40?

thinner is better to “wash” everything out

running a 30 weight oil over 100 miles won’t hurt anything and it’ll clean the motor better.

you can run 300v if changing every 6 mo

my buddy runs it on the street in his B5 s4 and gets great UOAs with plenty of life left in the oil. It is classified as a “race” oil so technically it’s not made for the street but I have saw data that supports running it on the street in short intervals.

My thoughts going into it were exactly what rtl5009 has conveyed above. 30 weight got the job done.
