When you say handbook; do you have an exact title? Or would the info be in an Owner's manual?
Mark:I have a 1980 vw pickup, 1981 vw pickup, 1982 vw pickup and 1984 Quantum Owner's manuals. The Quantum is dark green and has 102 pages; I have seen charts on the shift points of the various transmissions, (in both mph and Km/h), data charts for engines, (gas, 5 cyl, TD) and capacities for fuel tank, cooling system oil, etc, but NO reference chart for fuel consumption, gas or diesel. Only mention of fuel economy oriented to operator driving habits. Here is a quote in boldface type in the Economy section:"The published EPA mileage estimates may vary, depending on speed, weather and trip length. Your actual highway mileage will probably be less."Would there be anything in the Quantum 50 pound bible? I have one of those. Any otehr places I can check for you? ken
Interesting that the 1.6TD was rated a bit lower in fuel consumption than the 1.6NA.J.R.SoCal
