[More]Gas/E85 difference: The fuel economy of our Tahoe on E85, under these conditions, was 26.5 percent worse than it was when running on gas.
A motorist, filling up and comparing the prices of regular gas and E85, might see the price advantage of E85 (in our case 33 cents or 9.7 percent less) as a bargain. However, since fuel economy is significantly reduced, the net effect is that a person choosing to run their flex-fuel vehicle on E85 on a trip like ours will spend 22.8 percent more to drive the same distance. For us, the E85 trip was about $30 more expensive — about 22.9 cents per mile on E85 versus 18.7 cents per mile with gasoline.
