having trouble reading the numbers, cant find a straight foward answer, haha. Just trying to find how far you can go on 1 tank of gas from full to empty.. thanks guys

edit if it matters, say its mixed highway driving and backroad driving..

Take a spare gallon, fill up at your usual pump, ride until it stops.

oh snap. good call that would be interesting! thanks man!

Most I've gone between fillups is 166 miles. Highest MPG has been 85, but in 144 fillups, I've only crossed 80 MPG 5 times; average is 66 MPG. 2.16 USG is the most I've put in one tank.

Two of my 80+ MPG fills were with ethanol-free gas. It's hard to come by most places, so it's hard to separate the effect of the ethanol from the effects of the kind of riding I was doing near that station. : ) Because it's hard to come by, it's probably not worth optimizing for. Even if you lived in a town with E0 gas, riding a few miles out of your way to get it would negate the benefits.

With my 2020 HPE, I find I am getting 61 to 63 mpg so far. Hope that opens up as my previous GTS did. I haven't run it to empty, but generally fill up when the gauge gets to two bars (fuel light isn't on), and it takes about a gallon and a half. Only once have I gotten to 100 miles before fueling at that "2 bar level." On my previous GTS, I was regularly seeing 120 to 140 miles before getting to that approximate level (fuel gauge instead of bars). Ethanol-free gas isn't an option here - my mpg definitely gets better with the ethanol-free gas.

on a 2018 GTS 300, with 1600 odd miles right now, I am managing 120-135 on 2.2 Gallons all city riding stop go speeds going from 5mph to 70mph and all in between. I have a full windshield on. I will be hoping it improves in the coming months when the windshield & termoscud come off and I get some more longer rides out of the city, we shall see.

I did 270km on one tank on my Supertech but would not recommend trying that. There could only have been a thimble or two left in the tank.

Now that i have a Malossi lambda emulator (it does drink more) i assume a safe 220km of country riding but have not gone to the limit

At 95KmH (6600rpm) I get a constant 32Km per litre. If the tank is 8.5 litre, that does make it 272km all up...

At 130km it goes down to 27km per litre or 229.5 km all up..

Just Hwy use, no city..

On Gabriella, a late 2017 GTS300 ABS the furthest I have gone on a tank is 215km and topped it up with 7.33 litres for 82.86 imp. mpg. Overall my scooter is averaging a touch over 80mpg in all riding conditions and I regularly run to about 200km. The most I have ever put in in 24 fills is 7.4 litres. I need to be more daring!
.

130 miles is the most I've done. I usually fill up around 110-120 miles when the fuel light comes on.

I though you risked damaging the fuel pump if it ran too low, so I don't think it's worth the risk. Just refuel when you're around 100-odd miles at the next petrol station.

Just refilled now. I got 1.6 gallons & I saw that I had done 102 miles between the last fill up. So I think Im not getting more than 50-55mpg in this city riding.

I take notes in a Google Sheet when I fill up. Helps me get a sense of the range, and to expect how much the tank can hold so I can slow down before overfilling. It's also helpful for logging maintenance: for instance, I know I burn from MAX to MIN oil about every 1000 miles.

Here's the formula I use. I installed a Kübler tone ring at 6324 miles; original" mileage" is what my odometer would read if I hadn't done that.

Thats cool. I am guessing you could make another sheet & share it for people to use for themselves if they wish to.
I have a sheet which has a simple way for me to keep track of all the maintenance I do, when I did it, odometer reading, part replaced/changed (like Oil). I dont keep track of the mileage as I tend to fill up petrol/gas every 8-10 days or so.

Given my riding proclivities, I reckon about 130 miles maximum before seriously needing to think about refilling. Through various calculations, I've gone from a high of 74 miles-per-gallon (U.S.), to a low of 63 (in hot-rod mode, but I think that's likely worst-case). Having recently made a change-up in powertrain bits, time will tell what changes that's made.

I never think about range or mileage.

I keep a 5 gallon can of fresh un-ethanolled premium in my garage, and feed all my scooters and motorcycles from it. Not even sure what mileage they get, I just fill them up whenever they get low, or if I think I'm going to go for a long ride. That way, I rarely need to buy gas of unknown quality at strange stations, and deal with the 'residual hose problem' when I'm only buying a gallon or two.

Pretty uncommon for me to ride long enough to empty the tank, and not be back home.

I use Fuelly to keep track of mileage on all my vehicles. My overall average on the HPE has been 64.5 with a high of 80.6 and a low of 52.6 MPG. I'm in a semi-rural area, so I'm typically around 45-50MPH on the roads around here. Lower speeds might have better mileage.

I just did my longest distance between tanks on the scooter this past weekend with 120 miles. The low fuel light was on around 95 miles in with 2 bars remaining. I had 0 bars by the time I pulled into the station. I filled 1.88 gallons. Assuming all 2.2 gallons of usable fuel was available, I had ~20 miles remaining.

As my worst mileage would have been empty completely at ~115 miles, I find filling at about 100 miles is a reasonable margin of safety no matter how aggressive you are on the throttle.

I typically (pre-covid) used my scooter for a ~3 mile ride each way to the train station, plus any errands. With that, I only needed to refill every 2-3 weeks
