You know what’s funny? It might be my imagination, or some error in calculation, but I think my motorcycle, a 2015 Honda Shadow Aero, gets better fuel economy with E10 than it gets with ethanol free fuel.
When I owned the Nighthawk 750 I mentioned above, I used to use ethanol free fuel in both motorcycles because one would often sit while I rode the other one or drove my car. Since I sold the Nighthawk, I’ve been using the Shadow as my primary vehicle. In fact, I’m driving the car less and less, so I’ve stopped using ethanol free fuel for anything other than my lawn equipment.
Now, I acknowledge a lot has changed since I was using ethanol free fuel in the Shadow, including my riding habits and routes traveled, so I have no reason to chalk this up to the type of fuel I’m using, but with ethanol free fuel I was getting between 40 and 42 MPG. With E10, I’m getting 48-50 MPG.
Could it be that this fuel injected motorcycle, which is designed to run on E10, is actually more efficient with E10?
I’m betting other factors are at work, and the difference in fuel economy between E10 and ethanol free gas is so much less pronounced on a 750 cc motorcycle than a car that it’s mere coincidence. However, I know I won’t go back to spending extra money to run ethanol free fuel in the Shadow. It just isn’t worth the price.
