Well for me, money is the issue.
Don't get me wrong, I'd be happy to save money on oil but with $13,000+ to buy the sled I'm not going to stay home because it'll burn $10+ of oil on a ride.
Are guys comparing sleds that are still in break in mode?
My 19:1 tank was when the sled had 650 miles on the clock, I was done with break in at 300.
I didn't check gas oil ratio while in break in, but it hasn't changed much. I have checked MPGs for most of my rides, and MPGs didn't really change from break in to post break in, maybe %5 better after break in? But snow is inherently so variable that it's tough to know for sure.
Today was pretty deep, but there was decent traction underneath, but I'd wager I'm at about 25:1 for today's ride. I did put 5 gallons of gas in for 35 miles, 7 MPG, I'll go fill up oil now.
