Engine oil AMSOIL or OEM Honda

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.

I have never used anything but Amsoil in my LB7 Duramax for 12 years. It has almost 350,000 miles on it. I use Amsoil in everything from the weedeater right on up to the Duramax. Never one issue, and I only change it about every 20,000 miles.
