I took a 100 mile ride yesterday, the fuel guage showed just below half so I decided to fill up. My 2010 RSS took 3.7 gallons which is about 27 miles per gallon. Wondering what everyone else is getting. I have only had the bike for a week or so and this is the first time I checked the mileage. I was expecting somewhere in the 30's. I used 93 octane (etheyl) for you us old guys, most of the miles were highway crusing about 65mph, air temp was 80 degrees.:yikes:

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

We have checked mileage on our RT several times. At speeds in the 65-75 range we get 25.7 to 28.5 mpgs. At speeds in the 55-60 mph have got as high as 36.5 mpg.

How the right wrist is dancing with the loud grip affects everything in this game... 35 mpg here; but I shift early and ryde slow... (2010 RT)
I would discount that 27 mpg figure, Mileage will get better after a few miles on the clock, Remember no matter what the specs say the Spyder only holes 6 usable gallons. Also as you go though a few tankfuls, You'll find it's hard to fill the tank with exactly the same amount each time. So that will mess with your figures.

This has been mentioned by Murphybrown in the past, I believe she has a point. I was getting 30-32, I installed the Bump Skid Plate, running premium non-Ethanol fuel I got 36MPG. I checked again Sunday, I purchased regular non-Ethanol fuel because they were out of 89 and 93 octane. I got 38.25 MPG... The dealership service manager told me to run regular non-Ethanol fuel because it got the best mileage. I couldn't believe it. I have 2200 miles on my Spyder, I did not notice any less performance on the regular fuel. Hummm, I am puzzled but I do believe the skid plate was the huge factor in the increase. There are more than one vendor that sells the plates so I am not trying to promote any specific business on this board. I am just stating facts with a

Over the past 16 months and 15,000 miles, my RT has averaged about 28...some of that pulling a trailer. Nancy's GS has averaged about 29 over the last four years. Use of regular grade fuel in an RS may yield something slightly better. (Premium fuels have less heat capacity) Use of non-ethanol fuels will increase the mileage by about 15%-20% or more. Beyond that mileage varies from rider to rider, machine to machine, in different climates, with different local or seasonal fuel formulations, at different altitudes, and on different types of roads. The biggest variations are due to speed and the rider's agressiveness. I'd say what you are getting was about average for a new Spyder.

I consistently get about 30-31 mpg with my 2010 RTS. Have 22,000 miles on it now. I don't drive fast or hard, and use 90 octane fuel--the highest available up here.
Have over 13,000 miles on my 2011 RT mostly highway miles, I get anywhere between 35 to 40 mpg on the highway I set cruise control at 60 and leave it there, using 93 oct and get 27 to 31 in the city. I also found that after my 12k maintance fuel mileage increased and rides great.

6 gallon of gass
Why do you say 6 gallons, what happened to the other .6 gallons that they say it will hold?

It is unusable head space. Room for expansion is necessary in all tanks.

I rode my:spyder2: one time until the needle on the gas gauge was way below the empty indicator. It was scarry because I did not want to run out of fuel.
I had 180 miles on the tripmeter. It took 5.8 gallons to fill. I do mine the same every time so it keeps my mileage numbers pretty close as far as how much gas added. (31 mpg) this time also.

87 or 91 octane
87 works fine for me. label by the fuel fill on my 2011 RTs states 87 octane minimum. After TB updates at spyderfest my mileage went up into the 33 range on 87 octane with 10% alcohol. I see no reason to pay for premium and non-alcohol gas is difficult to find around here.
