Engine oil AMSOIL or OEM Subaru

I run Amsoil in my 100% in my vehicles and lawn equipment. It’s synthetic, uniform, and has low volatility unlike petroleum based products. Less frequent oil changes.

Amsoil did pretty good, it beat out everyone else from that project farm oil series.

I use Amsoil 0W-20 508/509.

I run Amsoil in both of mine. Also use all their gear oil and transmission fluid

I run 5w-40 in my veloster (2012 w/ 140k miles). An engine with that many miles has greater parts tolerance than it did when new.

I personally am a big fan of Amsoil of Motul 300v.

AmsOil signature 0w30. It exceeds the factory spec.

Amsoil ????

I only run Amsoil in everything I own from cars to lawnmowers. I use their signature series, but with the 0W-16 they only have their regular blend.

I like Amsoil. A lot of guys swear by Shell Rotella T6.
