I have been paying attention to the fuel gauge and mileage the last couple of months. I found some interesting tidbits. For example..., As we all know, it is important to fill the tank to the same level each time when checking mileage. That can be difficult to do sometimes with that ridiculous fuel filler inside the gas tank. If you are at a pump that you can pump slow, you can fill it to the top. If you are at a pump that fills relatively fast, the level will be close to the bottom of the filler. The difference can have a huge impact on mileage.
If I run my R3T on the highway and take an extended cruise at 70 - 80 mph, I will get anywhere from 205 to 215 miles left to go on a full tank. My mileage will be between 40 and 41 mpg. When riding around town or on backroads, I will get between 160 and 170 miles left to go on a full tank. The mileage is then in the 30's. The increased "stop and go" and/or "varied" throttle action seems to decrease the mileage. My point being, going slower does not nesessarily mean better mileage.
I was on the highway for about a half hour heading home after a long back road ride and actually watched the "miles left to go" increase as my ride on the highway became longer. I can only assume the closed loop mode was working quite well at leaning the old girl out on the highway drone.
