I became a "preferred customer" and bought Amsoil For my my DMAX and the Wife's Tahoe.
I agree its hard not to change the oil for 15,000. I will probably change around 7500-10,000 depending on how it looks.
Diesel oil scares me due to all the soot.
But one thing did influence my purchase besides all the great stories i ve heard.
I work at the Timken reaserch center ( yes, rollerbearing, steel, alt. energy )
and the scientists in the Lube lab have tested Amsoil against, Mobil, Valvoline, pennsoil exc.
The amsoil came out on top. lots of guys at work swear by it.
Our vehicles are parked in an unheat garage and start very well in cold weather.
But i just dont think i will spend another 200$ to change oil in both vehicles again. Frequent oil changes as Tony said are the key to engine longevity.
My dads 96 suburban- vortec 350 has 270,000 smoke free miles on Rotella 15w-40 since new.
