the company i work for has 17000 trucks and we have been running non synthetic oil at 30000k oil change intervals for at least 15 years. no warrenty issues with cummins, volvo, or detroit.
Do those trucks come with by-pass oil filters on them?
Well, that is impressive - 30,000-miles on conventional oil. So how does 409,000-miles hit ya?
