I finally did the dreaded ATF change on the 6 speed ZF transmission. If you read the fine print in the owner’s manual it says to change the ATF at 48,000 kilometers (30,000 miles)if the car is driven in harsh conditions, i.e. stop and go traffic. Not an easy job, but well worth it. This is the list of tools and materials: 1. Eight quarts of Pentosin ATF-1. This is BMW P/N 83-22-0-142-516 / ...

Anyone know of: cheapest source for Pentison? and, alternatives? I heard of a Product called M 6162 made by Febi/Bilstein that is supposedly the same spec as the Pentosin 7.1 Anyone have info on this product?
