Suddenly starting to use oil, not really smoking, where is it going.

Since it burns or leaks, how "smoking" is it?
What's the mileage? Year? Rings? Or, Valve Seals? What's the condition of the Crankcase Ventilation (PCV) system?
Give the engine a thorough cleaning? Then, start looking for leaks. Check your Front and Rear Main Seals?

A leaking lower intake gasket will cause oil and antifreeze consumption. Do a leak test on the lower intake, using carb cleaner.
