I will say I will not run Amsoil based on all that I've read and my own personal oil sample analysis'. I pulled samples out of several different diesel pick-ups. I'm no chemical engineer, but I compared Ams to Rotella T, T6, and Chevron Delo LE and was very disappointed in it. Amsoil is way overpriced and its quality doesn't even compare to much more affordable, straight dino oil like Delo LE.
