What’s your average MPG using what Octane Fuel?

[Revalden]

I have a DynoJet Power Commander 5 with their AutoTune and a Pedal Commander on my 2015 RT-S Special Series. Last weekend was my first ride with my club in about 2 years and my first ride with them and with the slow pace of the club and the new gadgets I got 36mpg. It's really hard to make my Spydie go this slow. 91 octane with 10% corn syrup.

You can look up stations on pure gas.org (they even have an app) for ethanol free fuel as a bonus they also list stations with racing and aviation fuel.

For instance there is a Sunoco in Glen Burnie Md. that sells 110 octane. You can find up to 115 at most airports that have access to the pumps.

While I was in Chicago at School back in 2003 I was able to fill up at a station on the street that had 105 octane. If you look for it you can find it but it is probably cost prohibitive at this point with the cost of fuel but I am definitely on the lookout for ethanol free 87 while I am on the road as a lot of the counties in maryland have banned ethanol free gas.

I finally got around to checking mileage yesterday. On a 160 mile ride, 2-up using 93 octane, we used 4.54 gallons. So that comes out to 35.24 mpg. This was combined roads. Some 65mph interstate, but mostly 2-lane back roads and going through a number of little towns with far too many stoplights.

At pure-gas.org I found a local station that sells non-ethanol unleaded gas.. price right now is $5.959 per gallon.
Guess I will stick with the super unleaded 93 octane for now.
I am getting anywhere from 37 to 41 mpg riding the same roads in the same manner.
I don’t know why the difference in mileage unless the Exxon station I use is selling a lower octane gas through its denoted higher octane pump.

Does a Cat Delete affect MPG? Thinking a bout converting to Lamonster 'S' pipe for heat mitigation. 2020 F3-T

I could not tell a difference in mileage or performance after the cat delete, but i could tell a difference in heat.

The short answer to a long story is, no. The machine's operator determines the MPG. And yes, the cat delete will reduce heat build up.

There is no real good reason to run high test, unless your one of these guys that like to mess with your ECU!! the bike will run just fine and your smiles for miles will go up in your bank account!

I'm thinking of switching to miles per dollar ...

I’m wondering why everyone is so anxious about MPG.....I mean, Why Did You Buy Your Spyder in the first place? Was it because it got such good MPG? or was it to RIDE. If you’re so worried about MPG then get a battery powered unit. No gallons to worry about. Of course then you can worry about MPC (miles per charge). I guess what I’m saying is “IT’S A PART OF DOING BUSINESS”.

To quote Peter “RIDE MORE, WORRY LESS”! Very sound advice.

At over $6.50 per gal for 87 octane I use what ever cost the less

Personally, I am concerned about mpg only on longer trips in the southwest. Certainly cost has become a factor, but mostly it's about being able to plan fuel stops.

I think the original intent of the thread has been lost. I think the OP was trying to find out if there is any correlation between octane rating and mileage (I don't think there is, based on earlier discussions) to justify the higher cost.

I agree with you up to a point, but whether you get 35 mpg or 33 mpg is not really the issue. What you are really concerned about is if yo can make the next fuel station, or should you fill up now, take extra fuel with you or plan another alternative. I also keep track of mine, but only as an indication of the health of my engine. There are just too many variables for me to compare, and that’s what the majority of posters are doing, my mpg results with yours....they’re going to be DIFFERENT!

I’ll get off my soapbox now!
