Based on every other parameter being equal, line my wife’s 2016 Dodge Durango R/T 5.7 Hemi which has run on real gas since the day we brought it home with 7 miles on it, next to a 2016 Dodge Durango R/T 5.7 Hemi that has run on ethanol since new and I guarantee hers will smoke the ethanol run car. Probably by 4-5 car lengths. And get better fuel mileage doing it. This observation is based on personal experience not something read in a blog or magazine. Bring it on!
