Average cost for an oil change

[Colossus]

Just paid $65.00 for a LOF at my trusted repair facility on my 08 Duramax.  Good oil, decent filter, good for another 5000-7000.

It is my understanding that the main reason is for the moisture absorption and the oil can get contaminated more from combustion by-products.  I guess they see most as to not go through a tank full of fuel often and if it sits then it can cause more problems maybe???

 

All I know is that my UOA's running E85 have been great if not better than when running regular fuel.  Plus if there are issues, why I don't see the reason, it covers AMSOIL as to not do extended.  I see online all the time those that goe 25k without UOA's.  I believe in AMSOIL but you can't go that distance blind.  AMSOIL also use to state that they recommend UOA's when doing extended drains as such.

You da man Nick. Love an honest dealer. Hat's off brother!
