I fill from a bucket, so not sure on actual quantity, but if I'm TOPPED off, I end up just above the 1/2 tank line each day. I can go 2 days on a tank, 2nd day the light is on 1/2 the day.
Don't buy into the propaganda of these things sipping oil... if you ride HARD... they use a ton of it, and they should. The only way these use less than average is if you're riding on the trail at some nominal consistent throttle level, and who cares about how much oil you use there?
Actually, I filled from a quart container day after filling my sled last weekend, and a quart didn't come very close to the top. I'd say my usage is about 1.5-1.75 quart/ hard day based on that now that I think about it. My 13 was the same, my wife's 14 uses a bit less, but she is more even keel than I am, as far as throttle usage, where I like to pin it more.
