Because I don't ever want to run the Injection Pump dry, I began to wonder what the tank capacity is...looked it up....should be 80 liters total with 11.5 liters in Reserve.....or about 21 Gallons Total with about 2.5 Gallons reserve...the above applies to 300D's bult after 02/83......all USA...Federal and Califunya

Therefore, at an approximate 28mpg, with a tank capacity of 20 Gallons I should be able to refuel at 550 miles and still have a couple of gallons in the tank.....I don't push this, because I live about 20 miles from the closest "on road" or "highway" Diesel pump.....

So......I was wondering why you only get 350 miles per tankful assuming that the only difference between our cars is the Califunya Emissions Package???
