Ive been using Motul 8100 5w-40 since I got it and have had good results. I dont put that many miles on the car usually (sits 5 days between drives, no stop n go ever) and have done one track day since changing it 3000 miles ago....car still shows almost full, have never seen any smoke or anything. Car never hit limp mode while doing 5 sessions on the track, highest temp I saw was around 260. Im going to change it this weekend and am going to use Motul again because I still have half a jug from the last change. Ill probably change it up after this just to see if theres a difference. Also just changed the power steering fluid, that junk was almost brown
