So it says on the packaging you can go a year 'guaranteed protection for up to 25K miles' between changes. I've watched a few oil testing videos on YT and the stuff definitely performs well. But is anyone really going a year between changes? I mean that'd be pretty nice. I typically change at 7K miles, and have been using Royal Purple until now. I could see doubling the mileage to 14K maybe... IDK. 14K sounds reasonable considering they guarantee up to 25K.
