Check out fueleconomy.org. Their new estimates (not the original EPA) are pretty accurate.
Are you calculating that based on the capacity of the gas tank, or is that how much fuel you used since you last filled up according to the pump?Ok I have the 2005 XLE with V6 and Im getting about 270 miles to the tank, If I calculate it correctly 270 miles divided by 17.5 gallons of gas = 15.42 MPG. How in the Hell is that? Something dont seem right. I dont have a lead foot by any means.
Thats how I do it, 17.5 gallons just seemed like a lot since that would mean you would only have ~15 miles before you ran your tank completely empty. If I fill up when the guage is right below the "E" mark, I can usually get in about 16 gallons.I based it on resetting the trip odometer to 0 when I fill the tank then waiting for the tank to run down to the low fuel light with about 20 miles left on the tank then basing how many miles are on the trip odometer divided by how many gallons to fill up. An example would be 270 miles on trip odometer filling up the tank with 17.5 gallons of gas. 270 miles divided by 17.5 gallons of gas = 15.4 Is this right?
