Engine oil PENNZOIL or MOTUL

Motul 7100 4T 10W-50 i use this and it's pretty good

0-20 pennsoil synthetic with a wix or napa filter

Same motor (same car) and I use 5w30 Motul 8100 X-Clean EFE

Motul 8100 Power 5w40 oil. My shop recommends it, I'm based in NC, Autocross in the summer sucks, but my oil temps drop back around 214 degrees F when I come off the track.

Unless you are tracking the car you aren\u2019t going to see a difference. I use Pennzoil ultra platinum and a wix filter on my daily\u2019s.

Pennzoil Ultra Platinum, better than mobil 1, but also I am pretty sure all oil is within a few percentage points of performance anymore anyways, and it really doesn't matter as long as you change it when you should.

Motul full syntetic 10w40, oem oil filter.

I use Motul in my built engine (not IAG) per the recommendation of the shop that built it.

I have been running Motul 5w30 Xclean EFE and have used Pennzoil Ultra Platinum as well.

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
