so i am leaving for work a few nights ago and for a split second, my low oil light comes on. i watch it and it doesnt do it the rest of the way to work, or on the way home. when i get home, i look at the oil window, and i cant see anything. so i go to the autostore, get some oil and a filter and do an oil change. About 3 qts of oil came out when i drained it. does out bikes just KNOW when we last changed the oil, it was damn near exactly 3000 miles *planned on doing the oil change this wekeend anyway*. anywho, what would caus 3/4-1 qt of oil lose in the bike? its not burning oil and i dont have a leak anywhere. or is that sound about right for our bikes as far as oil consumption?
