I didn't do the mileage thing but I went through a jug(1L) of the oil with 2 tanks of gas, maybe 2 tanks and a 1/4 at the most. Do you guys with 800 powerteks use around the same.

I do not have that machine, but the one l do have and most machines l am quessing it is normal to use at least one liter per tank of fuel, that is 50:1 or even 40:1 if your tank is 40 liters. Sounds to to me like your doing very well unless the new machines are different. The other thing is too that you will probably use more when it is colder than warmer.

07 Renegade 800HO. I'm using about a quart for every tank of gas. Approximately 105-miles per tank.

you should be burning just under a quart a tank. if your doing 2 tanks to a quart your pretty damn lean!

BTW, dont do the 'mileage thing', its not right. Your talking about a fuel to oil ratio, where the heck does mileage come into the equation?
