Owner reviews for engine oil

I use 10W/60 LiquiMoly 365 days.

Biggest thing I see here is the 400 ppm increase in zinc for amsoil, which will keep the cam happy.

Eneos X Prime 0W-20

Mine has had Mobil 1 Extended Performance 0w20 its entire life (aside from the factory fill) and I've had exactly zero oil consumption or lubrication related issues. It still gets nearly the same fuel economy and is as responsive and smooth as when I bought it, no matter if it's blasting up a steep mountain or baking in the heat of summer traffic.

0-20 pennsoil synthetic with a wix or napa filter

Same motor (same car) and I use 5w30 Motul 8100 X-Clean EFE

Michigan I use 0w20 Castrol Edge all year.

Every 4k-4500 miles with a Mobil 1 5w30-5w40 mix and some liquimoly oil treatment.

Castrol is fine

Do not listen to them. I have a 2015 forester non turbo I used 5w30 and had all kinds of problems id get codes for over advanced timing on one bank and under advanced on the other, I was getting power loss going uphill, weird chattering noise.
