Welcome to the site! :schild27::schild27::schild27:
Don't apologize for asking questions, that's what we're here for.
The most I've gotten is 10MPG taking it pretty easy on groomed trails.
On the other hand, when I was following vmax4rules I was getting about 5MPG.:3speechle
You'll probably find that the gas gauge is unreliable. On my sled, It starts out on the full mark, then drops like a stone. When it reads empty I've still got about half a tank. I reset my trip mileage when I fill it up and then go by how many miles I go before filling up again. I start looking seriously for a gas station around 70-80 miles.
