First off gas mileage will vary so much that my numbers are kind of meaningless but here’s a few numbers from my ride today . I filled my bear at home she was topped right up . At 38 miles my 4th bar checked out I was down to 3 . At 55 miles my 3rd bar checked out I was down to 2 I was watching closely . I then stopped and filled my bear up at the gas station it took 6.307 liters ( I’m in Canada ) . Looking at my manual my grizzly holds 18 liters . Doing the math quickly I should be able to do about 150 miles on a tank as roughly 6 liters = 55 miles so 18 liters should get me to 150 . 6 X 3 = 18 .

Now I just noticed that my manual says I have another 4 liters of reserve fuel , I never read that till now . So if that’s indeed the case your go a lot farther than the 150 miles . So the grizzly must hold 22 liters in total .
