Engine oil Mobil or MOTUL

Motul is the gold standard - the IMSA cars you see with Motul badges really do exclusively use Motul. The shop I work with uses it in classic racing cars that are worth tens of millions.

I used to use Motul 5w30 in my track prepped FRS just as an added layer of protection, even if it is placebo.

Bought my JDM STI bug eye and with fresh 5w30 Motul 6800. Car runs well.

I feel it makes the car run more smooth when compared to the oil changes I did before that were not motul.

Then when I actually tried it, noticing the engine running quieter and the shifts being a little crisper made me keep it.

Your ester based oils like Redline and Motul 300v will provide the best protection from the oil shearing on the track.

Anecdotally, Mobil 1 seems to burn off less than Pennzoil for me so that is what I use.

My 14' outback burned 1-2qts between oil changes based on driving (lots of short trips or visits to the mountains burned more.) Never had any blue smoke on startup or during driving.

Down to .5-1 qt low after 5000 miles now.

I've been running Mobil ESP 0w20 (VW508) since my 1st oil change at 3k miles (5 months into ownership), then another oil change at 7600 miles 10 months later. I've ran a few Auto-X events, a light educational track day (not pushing the car too much), and certainly am otherwise not shy with the throttle at all. I have also had 1k miles on my stage 1 tune since July.

I was using Mobil1 ESP 5w30 in my 530i XDrive.

I tried Motul but the oil consumption was bigger with the Motul.
