i use conventional oil but not the cheap stuff and i have a good filter put in i was having jiffy lube do my oil changes and found out the put crappy filters and oil in my truck.
i have 106k miles on it and do a LOT of highway drives... no towing. my book says 6k for oil change is that ok to do with higher mileage? this guy i work with swears i am going to kill the life of the engine if i don't change it at around 3k... he says until 75k it was ok to go 6 k but now its over 100k i need to change to every 3 k.... does this make any sense to any one?
