A study released by the University of Nebraska found that E85 delivers more efficiency over higher petroleum fuel blends, offsetting much of the loss in Miles Per Gallon (MPG) typically attributed to E85. The study illustrates that when calculating fuel MPG performance, both the energy density of the fuel (BTUs), and the energy efficiency must be accounted for.
The report tested light, medium and heavy vehicles showing E85 improved energy conversion by 13, 9 and 14 percent respectively when compared to higher petroleum blends. This increased efficiency translates into an MPG decrease of only 14 to 19 percent depending on vehicle size using E85, showing that energy density and efficiency of fuel both factor into overall MPG performance.
This difference in MPG is compensated by the lower price of E85 blends at the pump that are on average 20-30% less than regular unleaded. In fact, Propel E85 is nearly 60 cents cheaper than regular gasoline, making E85 the ecomomic choice.

We are using the E85 Fuel for our
1991 Mercedes and 1992 Cadillac.
We have gained 1 to 2 miles per gallon. Up from 18 and 19 MPG to
20 to 22 MPG
