I pour a couple ounces of oil in the filter out of a measuring cup with 7 oz of oil in it, install the filter, then pour a gallon and the remainder of the 7 oz cup in the crankcase, and don't worry about it for 4000 miles, when I change the oil/filter again.

It doesn't matter what I ride, where I ride, how fast I ride, or how far I ride... it only matters THAT I RIDE...EVERY DAY. "Ferret"
