What most people don’t realize is that their car use is actually severe conditions. 10k is good if you do a lot of long trips but if you are doing lots of short trips and if you have severe hot or cold weather you’d probably benefit from a shorter oil change. I haven’t researched it at length but I’ve also watched some videos where people send in oil samples for analysis after different oil change intervals that show a substantial difference in oil quality between 7500 and 10000 mile changes
