60 000 miles is the regular service interval. severe service ie towing would be more frequent...not sure what the service manual says


i would do it at minimum, when its black...that could be every 20 000 miles. that is why it is checked at every oil change.




All times are GMT -5. The time now is 6:17 AM.
