Another question, though. I got a 5 year/100,000 mile warranty with the truck (3 yr/36,000 bumper to bumper; 5yr/100,000 power train). Power train does mean engine, tranny, etc, right?
Yep. Tranny and Engine. Not the accessories, not the computers or stuff like that. The computers are covered by a 80k mile Fed warranty.
I've used ASL and sadly was not impressed. If I ran Amsoil in my engine the XL is the only stuff I'd run personally.
Someday when I have to make another order with Pablo, I may get a case or 2 of 5w-30 XL to play with. It is the only syn I'd even think about paying full price for. All others have to be discounted.
Also you will gain NOTHING following the OLM and using ASL. XL will do EVERYTHING ASL will do and IMO with you following the OLM.
Take care, bill
