Engine oil Mobil or Shell

I’ve been doing annual oil changes with the mobil1 15/20k oil and 15/20k filter. Oil comes out clean every year, no problems.

I've put Mobil 1 in everything I've owned for the past 30 years and change it at 10,000, but I'd never push it to 20,000.

Mobil 1 esp 5w30

$33 for a jug at AutoZone.

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
