Absolutely TRUE Amsoil story -
I got a case of Amsoil crankcase oil as a gift from a buddy who works at a third party supplier.
Engine had 185,000 miles at the time. After about 1000 miles on that Amsoil I had so much sludge under the valve covers - it freaked me out at the time.
I drained the oil and decided to just use the rest of the Amsoil up that I had. Again I got that sludge , but not as much.
So I went back to using what I was -Castrol 50/50 Syn blend and didn't get any sludge.
This is what happened - Norm was the one that explained this and I believe that is what happened -
The Amsoil cleaned my internals so well, the sludge was a side effect to that. Yea , it was cold and I frequently made short trips, but the engine never had anything like this happen when running Castrol - I keep a pretty good eye on things. I want this truck to last me.
Hands down that Amsoil IS good sh^t - To expensive for me to run in the crankcase. I like to change the oil every 3k and won't have it any other way. However, I do run Amsoil in my E4OD (trans)/ Gears/ T-case/Power steering and now having 238,000 on the truck; she runs smooth, shifts perfectly (stock trans).
At one time it wasn't this smooth at higher speeds. It is now and has been for along time since changing the drive train lubrication over Amsoil products.
