RE: 5 gallon gas tank

How are you figuring your mpg? It shouldn't matter how big your gas tank is. Just look at your gas receipts and use the gallons on the receipt to figure your mpg.

RE: 5 gallon gas tank

Miles driven devided by amount to fill tank should = MPG. That is taking into account that you are starting with a full tank, and adding fuel to bring it to that same point.
Size of tank has nothing to do with it.

Is that with or without using reserve? Without reserve you are probably only using around 4 gallons.

RE: 5 gallon gas tank

But how much are you putting in each time you fill up? Do you actually run all the gas out before you fill up each time?

You need to refigure how you are measuring... and I have a bridge for sale in Brooklyn...

Is that how you're calculating your fuel mileage?? Are you running the tank totally dry each time? If not, then what you're saying here it totally wrong.

One thing you need to realize, the tank capacities that manufacturers claim are usually pretty close but it can vary be a couple of tenths of a gallon sometimes. I once put 6.2 gallons in th "6" gallon tank on my 1983 BMW. Having said that, it's also possible that not "all" the fuel in a tank is accessible to the fuel pickup line.

If you want to know what mpg you're really getting, fill the tank at whatever gas station you want. Zero the trip meter and ride the bike. When it's time to refill, fill it in the same manner and to the same level as you did before. If possible, do this at the same station and pump, with the bike oriented in the same direction. That way everything's in the same position. Having the bike leaning a little more or less one way or the other can "sometimes" make a difference in how much fuel you can get in the tank. Anyway, divide the miles you rode by the number of gallons you just took to refill. That's it! To get an accurate overall knowledge of your fuel economy, you need to do this over a number of fill up's. Doing it just once will give you a number but milage can vary by quite a bit under the right circumstances.

Ride Safe,
