The manual says around 20-30%...I am not sure why they would have a MID if you have to change the oil at 60% ...Is my dealer right or do they just want the extra money for the oil change Thanks Keith

I just saw a TV Show on Car Maintenance with Goss' Garage, the guy from "Motorweek". He said the factory oil change on-board indicator is a guestimate. The car computer uses references that aren't true to actually when the oil needs to be changed.
He still recommends changing the oil every 3-4,000 miles. Change it more frequently with primarily city driving. Contaminants in the oil get suspended and are like sandpapers to the cylinder walls, bearings and other vital engine components. It's cheaper to change the oil more frequently than to do an engine rebuild.
