The Weather is HOT and the MPGs are UP!

Heres my figgers:

If the mileage goes from 28 to 34 with the heater thats a savings of $2 (half gallon) per 100 miles. So in 5000 miles thats a $1000 savings.

Block heater is $80.

Is that right?

No its 50 x $2 which is $100.

Pays for itself in a year.

Electricty is 12 cents kwhr x 1 = 12 cents per day to heat. .12 x 180 days = ~$20? per year for electric.

You're missing the cost of electricity. So you save $2 per 9 days or $0.22 per day. Block heater is probably 1,000watts (1kWh) so if you leave it on all night for 6 hours that is 6kWh. Around here, electricity is about $0.13/kWh so it will cost you $0.78 per day. Even if you have Time-of-Use rates (cheaper at night) that will probably be $0.06/kWH or $0.36 per day. So, as others have said, you won't save any money really...
