My wife just turned 101k miles on her Jeep. I have only used synthetic 5w20's its whole life changing around 7.5k. I have one jug of QSUD 5w20 remaining - I notice the store has QSUD on sale and I thought it might be a good idea to start using a high mileage. I figure I could go 50/50 with my current jug and HM for the next two changes and then use HM after that. The Jeep does not have any leaks or burning oil issues or anything like that but I would rather be proactive about it.
Good idea or stupid?
