oil change intervals should be based on engine revolutions not miles. Your engine oil doesnt affect your tires and your engine revolutions are not counted by the odometer. If you drive 5000 miles almost all highway, running at 2k RPMS or less, then the engine would actually have less revolutions on it than a vehicle driven in stop and go city traffic for 5000 miles. JUst a thought. Now since there isnt an revolutions counter on our cars then I think you should change your oil based on your driving habits, and changing your oil too often doesnt hurt anything.
