Unlike normal 2 strokes, the E-TEC's inject oil directly into the main bearings, crankcase and cylinder liners. Accumulated oil is recirculated from various locations in the powerhead via internal passages and external hoses, fittings and check valves.

The local dealer sells XD-100 full synthetic oil in bulk (bring your own jug) for $35/gal. On average I seem to use about 1 gal of oil for every 100 gallons of gas, which works out to about one gallon of oil for every 400-450 miles run, so the cost of oil doesn't seem to be much more than what I'd spend on changing the oil and filter every 6 months on a 4 stroke.
