Since 3,000 miles is easy number to remember, I change my oil if mileage on my odometer is diivisable by 3,000. I also mark it on the calender, so I can review it quickly. Always keep spare oil filter and 4 bottles of 100% Synthetic Motorcycle 20W/50 available, so I do not have to "run" to the dealer and take advantage of weekend or coupon sales to get discounts of up to 20% for stocking items.
