I understand that the harder you ride them the worse the milage you will get. It is still good mileage for sure for riding them hard. It is the oil that is surpising me. I thought these were supposed to use less oil but basically from the numbers I am seeing above (and off the top of my head figures) you are useing 1 qt roughly to a tank. That still makes it 40:1 roughly?!?! Correct or am I missfigureing...If this is the case they should not advertise them as useing less oil but instead better milage.... ;*]. I know what you mean thought because on my attak I have been averaging about 14 and a lot of people tell me that is on the low side, but I ride it as hard as my 01 800 doo and I only got 8 mpg out of that (which my boy rides now and gets 12 out of)so I am still happy!!!! Wife has an 07 Blizzard 800 and she gets just a tad better then me so I will have to see what this new e tek pans out like. If it ain't gunna get a whole lot better I think every sled from here out will be a 4 for me.....(maybe ha ha)
