Fuel Saving Tips
Modern TDI engines require good lubricity in the fuel. VW warrantys are not voided by using up to 5% bio Diesel in TDI engines. Studies have shown that blended bio diesel provides lubricity that is often lacking in ULSD. On a recent warraty fuel service I was told that I had the highest quality diesel fuel of anything that has come through my dealership and that my fuel system was in tip top condition as a result of the added lubricity.
