But with amsoils extended drain intervals, you can run up to 2xoem or 22000 miles!


:roflmao:

Any 15-40 is fine, because after the first 5 mins of running, id change it again.

That's nothing; my grandfather used to run Amsoil for 3 BILLION miles, and when he did a compression test, his motor actually had 230psi MORE compression than factory!!!
