We use Amsoil in everything here. Top quality oil, but like Heath said, if you are stuck on 3-5k oil changes, it is a more expensive venture. If not, then 15k drain intervals, better mileage and wear protection await you!

 

Run only Rotella on the farm and in my truck.

 

use 3 gals of rotella 15-40 in my truck, yes its a quart over but it goes somewhere, its not going to hurt the truck

 

thanks for all the very helpful replies.
