It doesn't matter what Octane I use. I get the same millege whether I use 84.5 or 102. The only difference is the price.
Note: I aways use at least three tanks of the same ocatane when I experiment.

I actually tried this on my way up to atlanta yesterday. I didn't really notice any difference in the mpg no matter which octane I used. I averaged about 150 miles per tank no matter what.
I guess my real question is, why would my mileage drop so dramatically when I switched back to regular(after only one tank of premium.) It looks like I took two steps backward. Like I said, I had always gotten 29-30 miles per gal on regular and now with this last tank it dropped to 22 +/- after the experiment. Is there something in the software that makes adjustments going to premium but may have failed to make an adjustment going back to regular. :dontknow:

I got 27 mpg until the BRP "fix", now I get 18. I was told that was "within the normal range". Doesn't matter how I ride it, I get roughly 90 miles to a tank.
My dealer is 36 miles away - round trip is one tank.
I don't know if your means of measuring your MPG is valid -- but, if your are getting 18 MPG there is a problem with your Spyder.
To ensure you are working with valid facts . . . Fill your tank and mark the mileage on the odometer. Then, each time you fill up over the next several tankfuls (3 is the absolute minimum -- more fills are better for accuracy) make note of the gallons you put in your Spyder at each fillup. After the 3 minimum fillups, make a note of the mileage on the odometer. Subtract the first measure from the the last measure and note the miles. Divide the cumulative miles by the sum of the gallons and note the result. For example, if your 3 tanks are 450 miles and your total gallons are 15.0 then you got 30 MPG.
The Spyder tank does not allow you to fill it once and measure the mileage accurately.
Check my mileage on the Fuelly link in my signature. You will see what I got for an average (34.5) over 25 tanks.
I filled up today and hit the 27 mpg... I think the biggest difference was my shifting and driving RPMs... so I appreciate what you all wrote on here- it really helped me out.
:) Thank you!
