Engine oil Shell or AMSOIL

Amsoil 25k Oil in a 2017 Ford Focus. Went 20k miles. Looked like standard 5k oil when it came out. Engine is still doing great 60k later! I do 7500 mile changes with Royal Purple now.

I use Amsoil in my Ford Fusion.

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).

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’ve been using rotella for years in all of my equipment. It’s very good oil

I personally use Shell Rotella T6 5w40 for the fact that I live in the florida and the heat is killer.
