I'm 1500 mi. into the rinse phase of an Auto-RX treatment. I need to drive it on a 700 mi. road trip tommorrow. Should I go ahead and change the oil now, or wait until I get back. Thanks.
You could change filter and top off if you don't have time for Dino Oil Change ? This would be great trip to start rinse cycle . Hope you can just drop current oil and change to rinse oil.
