Gas prices in Alabama show to average $3.00 a gallon for regular and $3.65 for premium. Pumping in five gallons means $15.00 vs $18.25. If the $3.25 difference is that significant to you may I suggest trading your bike for something like a Honda ADV 150, it gets 75 MPG.

I run as high an octane gas as I can get. If I run regular (87) in the EVO, it vibrates and runs a little rough. If I even try to run that crap in either one of my dinosaurs, they will HATE me for it. I ran some 100 octane aviation gas in the ironhead a few times and it loved it!

Where I live ALL grades of gasoline are $2 a gallon higher than the price last year. Gas was cheaper simply because demand was lower when some businesses and other things were shut down. Current prices near where I live in SW Ohio are currently 3.39 for 87 octane regular and 3.82 for premium or 91/93 octane, or a difference of 43 cents. What is the difference in price between regular gas and premium right now where you are at? I'm on a fixed income and hate the high prices but for me the extra savings to run regular in it isn't worth risking problems.

I've ran regular in it occasionally and for very short periods (only because I didn't have a choice at the time, and it ran okay, except the check engine light came on. The light went off after I put in a little regular, and it went out after I got to another station and topped it off with premium. The second time premium wasn't available I used octane booster, and the light went out that time too.

That's one of the joys of living in a wannabe socialist country where the government knows what's best for us and charges us peasants a carbon tax plus clean fuel standards tax etc etc etc on fuel so that we can somehow clean the planet of pollution created in China...

Anyway, I digress.... You could certainly get away with running a lower octane fuel but I refuse to run any fuel containing ethanol in my motorcycle (unless I am stuck in the absolute middle of no where and the only other option is pushing my motorcycle home). Even then, I would not want to go below the factory recommended octane rating. Its an ancient, large displacement, air cooled V-Twin engine design. In order to provide sufficient performance and safety from pinging/detonation and all those other really bad things, you need to run a higher octane fuel than the typical modern engineered liquid cooled multi cylinder grocery getter can handle.

That my two cents (which when converted from Canadian to American funds is worth considerably less)....
In Canada all shell service stations, mobile service station and others sell their premium 91 octane without ethanol.
