I run Royal Purple 5-30w in my Raptor. It has set in the garage for most of the Winter. My question is how long can you go with out changing the oil. I was always told 3 months or 3k miles. I may have 300 miles on this oil change. Do you still have to change your oil due to time restraints with todays synthetic grade oils? I just feel like I have been wasting money in the past by prematurely changing the oil.
12 months or 10,000 miles on model synthetics and engines. anything more frequent is just burning money.
