If you do the drain and fill, then take it for a short drive, and the repeat, then another short drive and repeat again, you will approach a 100% fuid change.

Do this process at least every 30,000 miles.



I think RoadRunner and Phil were not too supportive of that long of an drain-interval. I think every 12k miles is what was recommended. As Jim said, do the fill and drain a few times until you get a healthier pinkish color (shouldn't be more than three trials).
