Engine oil Castrol or Shell

High mileage oils like Castrol edge have more detergents than other oils, not a marketing gimmick.

Change my e90 n52 every 15k, castrol titanium 10w-40. blackstone reports confirm the oil still meets spec with plenty of detergents left. Showing no signs of wear at 170k.

Just to add my two cents, I am using Shell Helix Ultra ECT C2/C3 0W30 (it is basically the same as Pennzoil Euro 0W30 in the US) in my AGU 1.8T (150bhp) after I have killed an AGN 1.8 (125bhp) by using 10W50 for about 8k miles (I was flooring it a lot). I bought an oil pressure and an oil temp gauge after I have killed the 1.8, and the oil pressure seems to be perfect with the 0W30 (the engine has about 100k miles on it).

I just run castrol edge on mine. No issues.

Just get good oil. T6 is one of the best oils for EJs and it’s dirt cheap.

Nothing goes into my trucks other than Rotella T6. It's a great oil, so oil changes can be spaced out over a longer period.

Looked great on the Rotella ????????‍♀️ I change every 5k right now on the Motul but should get a new analysis done on that.

But yeah I use Rotella in all my vehicles and small engines.

I’ve used T6 in so many different engine types without a single issue or excessive wear.

I used some castrol 5w50 at my last race. Oil temps saw like 270F.
