Hi there,
If the oil is not leaking externally, then it must be going out the exhaust. Check spark plugs for any signs of oil burning, a dirty build up of deposits will indicate oil consumption, also lack off regular oil changes and the wrong oil will result in low oil levels. The white smoke can indicate water in the combustion, keep a close eye on the coolant level and remember, that a temp gauge will only work if there is water around the sender, so very low coolant levels wont always equal high temp readings.
