Oil Changes
I am running Amsoil synthetic and I change my oil every 15k miles and the filter every 7500. I am now using the Donaldson Endurance filters instead of the Amsoil filters so I probably should stop changing the filter every 7500 miles. i think I read where they can go up to 25k, but you are supposed to change the filter everytime you change you oil.
The longest I went was 32k on one drain interval but I was doing oil analysis at the time.
