Hi there,

The oil must be going out the exhaust or on the ground, it cant go anywhere else. If you have no external leaks, check the spark plugs for signs of oil burning,(whitish deposits) the burning may just be minor but constant. Try changing the weight of the oil and keep the services up as oil oil will burn off quicker than fresh.
