Would plugging a vehicle into a block heater for an hour or so prior to
start improve gas mileage?
I drive a S10 1.5 miles to work one way and get 13 mpg, on the highway, I
get 26 mpg with this 6 cyl.
Being that gas is about 3 buck a gallon and elect is approx 13 cents per
KWH, I figure I would have to see approx 4 mpg improvement in my short trip
to work to break even. I think typical block heaters use 600 watts.
Because I live in Iowa and do not garage the truck, I suspect a preheated
engine would help more in the winter and not ias much in the summer. Also,
I would believe that if I had a long distance drive to work that the small
perheat would not affect overall mileage as the engine warms up on its own
for most of the trip and does not contribute any amount to the overall trip.
Anyone ever work this area?
