I'm hoping to get better mileage with mine this year as it gets fully broken in. Last year when it was new I only got between 12 and 15 mpg.

 

I think I have 20 or 21 miles on it and it is on E. This is the first tank though.

 

My very first tank was like 3 miles to the gallon. I was seriously disappointed with that consumption. However, I must stress that I was pushing around 30" of snow and clearing paths all through that tank. Now that we are starting to break in the consumption is much better although I am still doing a lot of work with it and playing around the farm. 0-30 mph in around 200 yrds and then shut it down is pretty hard on the fuel economy.

After I picked up momma's new 500 this last weekend we ran around our little section of property putting on about 7 miles or so. It was gentle, just putting in Low range, up down all around. and so far I haven't even moved off that full mark.
Can't wait to see what it really is for mpg but it seems to be improving.

btw, it is still under 40 hrs on it so I wouldn't even consider the 800 Broke in by any means.
