engine oil

[smoke240]

Just wondering what oil everyone uses. Please say what engine, oil weight, brand, and how aggressive you use your car.

I have a sr using 10 30w, royal purple, drifting at least once a month and the occasional aggressive street driving.

There's already a thread for this. SEARCH.

I was running Royal purple previously and it is garbage in my sr20. I now run amsoil 5w30 signature series. Car ran alot better and smoother. Oil is still clear after 4000 km and it sees alot of heavy track haha. amsoil the way to go

Royal purple is garbage for daily use. Plus it's purple, hard to tell when it's dirty. I run delo 15w-40 in my lil single cammer. Made for diesels so I figure it can handle it lol, plus my shit leaks and its cheap
