My car is burning thru a quart of Mobil 1 Turbo Diesel Truck oil every 500 miles and at $7.50 a quart is getting expensive. The car was converted to a Golden Fuel WVO 2 tank system and runs great. It does make a slight light blue smoke. Is this excessive motor oil use related to the Veggie oil system? Other E300 TD owners experience this?
