I do believe that depends on how the car is driven. My feild truck is every 12000 miles maxbecause of all the lease roads I drive on.That poor thing is rarely clean for more than a day, and sees many miles of caliche roads. With the lack of rain weve had, its very dusty. Almost like driving on baby powder in some places. And I mean 4wd required fine dust. Its crazy. I dont have anything else that goes more than that really because i change it once a year, regaurdless of mileage which I know is less than 10000 miles on the most frequent one.
