I agree that driving style makes a big difference and it doesn't cost anything. I was actually averaging 13 mpg city but I am up to 15 which is still pretty sad. 90% of my driving is short trips in town but I only spend about $150 per month on gas so replacing the Bronco doesn't make sense since it serves my purposes and I don't have much money into it. I figure I could save one third of the fuel or about $40 per month by subsidizing it with grid power. I already have a spare dc motor, six deep cycle batteries and I can build another controller for $200. If I had to spend a couple thousand to do it it wouldn't be worth it to me. Would you believe I'm thinking of mounting the motor in place of the AC compressor (doesn't work anyway) and using a chain drive off the crankshaft?
