Fuel consumption is relative to the rider.(same as belt life)
A whole group of guys can go out for a ride and stay in close proximity to each other, the miles accumulated will not be the same, fuel consumed will not be the same.
The guy that uses the most fuel in ur group, will likely use the most fuel no matter what brand sled he rides(to a degree).
Usually the younger guy that never sits still uses the most.
Or the guy that likes nothing but highmarking.
Highmarking will net the worst fuel economy as ur full throttle with the lowest track speed.
Worst case should be no less than 3mpg (i pitty the fool that gets worse [emoji28])
Best case could be as high as 7-8mpg.... for the trail riders.
