A guy at work has a Dodge diesel and he goes 25k on his oil changes using Amsoil. He has almost 300k on the engine with no issues and he has sent samples in to get tested.
And I've got 385K on my dodge diesel with shell rotella T dino oil
Amsoil is a scam, I wouldn't use it on a bet.
Dad has the 2007 Dmax. He is retired, and spends a lot of time researching on the internet. He came across the Amsoil scam also. Wanted to go full synthetic so he could go longer intervals between changes. Changed the oil and filter, and cranked it up. Few minutes later, he could here a distinct tapping sound. It hadn't left the drive way yet. Dropped the brand new Amsoil out, put a new filter, and went back with the Delo. No more tapping. This truck is babied, and my old man is anal retentive when it comes to maintenance. I hope he buys a new one soon. I really want his "old" one. He deleted the 9th injector, and put a thru exhaust on it. Has the programmer for the delete also. Also did a reroute of the PCV so it doesn't go back thru the turbo. Man does that truck run..
