How much gas have you saved?

[Ford Man]

I decided to see how much gas I had saved since joining www.gassavers.org. and posting my first fill up on 05/10/2008. I based it using EPA combined estimates.

For my '88 Ford Escort Pony
Old EPA Combined 37
Miles driven = 7506.9
Gas used at 37 MPG = 202.88 gallons.
Gas used at lifetime average 44.91 = 167.15 gallons.
Gallons saved. 202.88 - 167.15 = 35.73
Enough gas saved to travel this distance at lifetime average. 35.73 X 44.91 = 1604.6
Dollars saved at $3.75 per gallon = $133.99

For my '97 Ford Escort Wagon
Old EPA Combined 31
Miles driven = 2763.2
Gas used at 31 MPG = 89.13 gallons.
Gas used at lifetime average 44.76 = 61.73 gallons.
Gallons saved. 89.13 - 61.73 = 27.4 gallons.
Enough gas saved to travel this distance at lifetime average. 27.4 X 44.76 = 1226.4
Dollars saved at $3.75 per gallon = $102.75

Total gas saved = 63.13 gallons in 20 weeks.
Total dollars saved = $235.74 in 20 weeks.
Enough money saved to buy 62.86 gallons at $3.75 per gallon.
