I get any wheres from 44 to 50 mpg, all depending on my style of riding for the day. With a 6 gallon tank, I will usually stop for fuel around the 240 mile mark on my trip odometer.

Not that difficult to figure out.......

 

I have a 2013 FLHTK and usually get about 225 out of 6 gallon tank. I'm usually looking to fill up at about 175 though.

 

Most from one tank....230 miles....I have averaged 42.3 mpg.... best 51.1 mpg....worst 34.3 mpg.
I record every gallon of fuel used. I always go by odometer....I will never trust the fuel gauge. I like to know how far I can really go. 200 miles and I'm lookingfor a station. With no reserve, I certainly don't want to push!

 

I typically get 40 mpg. I reset my "B" tripometer to zero at every fillup and keep an eye on it during long rides. When it reaches 200 miles, I look for a gas station. I have a 6 gallon tank.

 

The gas light comes on about 150 mile mark.
'07 5 gal tank.
I usually have about a gallon left after the light comes on.
MPG is governed by too many iffy's such as speed, road, wind, etc.

I'm not interested in seeing how many miles I get a tank.
Some riders forget the fuel pump is cooled with the surrounding gas.
If the pump isn't cooled, it can burn up.
An expensive problem.

 

14SGS ,SE ac,FP3,V&H twin slash rounds. I have checked every tank since day one,34.6 first tank. I Was worried my 09fxstc was consistently 48 plus and as high as53. All stock except slip ons. I thought my stage one on my SGS from day one was a mistake. But my mpg has gotten better with miles, now avg 40 to 45 hwy. I'm not an aggressive rider but do open it up occasionally.

 

2005 ultra ,5gal tank , been 210 , but usually fill around 180 , light comes on around 200

 

6 gallon tank, basic stage 1. Low fuel light comes on at 200 miles, like clockwork. I average right at 41 mpg.
If I stop immediately, I can get 4.9 gallons in the tank. 227 is the farthest I ever felt the need to push it. I was sweatin' bullets.

 

05 EG classic, injected TC88 with intake, exhaust, cams and tuner and my mpg sucks at about 32.

 

I routinely get 260 KM (161 Miles) to a tank but this is city riding - country mileage would be better.
