The sled we left was a 13. My 14 ran out at 46 miles but has a bb. Same trip my other buddy made it 18 more miles and his 14 ran out. All off breakin. Maybe they are good on trail but if you are on the gas all day they are not that great. The Pro uses less of both under those circumstances. When the we're first promoting the etec they were claiming fill oil once a year. Far cry from that. The Pro uses less oil irregardless. Every sled is different but those are the ones I'm around all the time.The T3 is the first big step in the right direction doo has taken with respect to the tunnel clearance issue, the doo tail has always been dragging in the deep more then it should, the pro is very good in this department because of its sleek and slender tunnel design. You all remember the rev tunnel....what a nightmare!!
Is the sled in breakin mode still? The motor should not be using that much fuel and oil even pinned, unless your still under 250-300 miles on the sled.
