Another fuel mileage debate...
Hello guys,
My 90 Chevy is a shortbox regular cab, 350 TBI, 700R4 (lockup not hooked up yet) and 3.42 gears. I've got a front and back plow on it and drive 50-55 mph to work. The only way to really tell is to try this out, but I have a theory yet to be proven. http://www.fueleconomy.gov/feg/driveHabits.shtml This link says overdrive always helps because it lowers engine rpms. I agree, in a passenger vehicle. BUT if the engine drops below a certain rpm with so much weight, would it be better for me to leave it in drive instead of overdrive? It seems more responsive and the truck isn't lagging as much. Any input? I assume the plows add another 600-900 lbs with all the heavy brackets, pump, valves, hoses and whatnot.
