I have not really clocked the actual oil mileage on my 02 800EFI, but I typically fill the tank befor a ride weekend and have filled the gas tank 3 times without the oil light coming on. I would estimate 275miles.
I've set mine for a 70/1 ratio as recommended by Big Al on Amsnow Online. I've been running Klotz but just changed to Blue Marble and must now monitor my usage again as it may flow differently and require further adjustment to stay at ~70/1.
