Stanadyne diesel fuel conditioner. Save $10 by buying by the case! Case of 12 16oz bottles. Each bottle treats 60 gallons of fuel. With the new low-sulfur fuel now at most gas stations, it is even more critical to run fuel conditioner in your VW diesel. The 2006 and later diesels are designed to run on the low-sulfur fuel. Earlier cars are not, and they rely on the sulfur as a lubricant for the injection pump. Low sulfur = less lubrication = injection pumps that wear out quickly. To prevent this issue we (and Volkswagen of America, Inc.) recommend VW diesel owners use Stanadyne Diesel Fuel Conditioner. It also reduces fuel gelling in cold weather.
Match Stanadyne diesel fuel conditioner with a high performance fully synthetic oil. It provides superior wear resistance and reduces sludge build-up for improved engine life. Also, don’t forget your magnetic oil drain plug to prevent metal from traveling around your engine in the oil!
