Engine oil RED LINE or AMSOIL
I use redline hp 5w30 for my n54. 7500 mi intervals. I’m at 113k miles currently. At about 90k I send my oil off to blackstone for an oil analysis. Came back in very good shape and they indicated I could easily go to a 10k mi interval.
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 use redline high performance 5w30 and I don’t burn a drop of oil even with 7500 mile intervals on my n54 powered 335is…With bmw synthetic my car would burn about a quart at 7500 miles.
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.
