Engine oil AMSOIL or FUCHS

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.

I keep using AMSoil after seeing a test results sheet from Blackstone (i think thats the labs name) for my 6.0. Tested after 15k miles and was better than 400 mile motorcraft.

Amsoil Signature Series is all I have ever used, I will recommend it.

My preferred is Amsoil 10w30, the good stuff. Seem to burn less of it off when driving hard.
