Perhaps oil has leaked onto the exhaust manifold.

Oil LeakOil leak, probably valve cover gaskets need replacing or just tightening. Also if it started suddenly after an oil change, the filter may be leaking, or you spilled oil on the manifold.

This MY & others had problems with both the cranshaft oil seal. The rear one leaks onto the exhaust and can make a horrible burning oil smell, notably when you stop after a long drive.

Head Gasket

Outbacks up to 2001 have issues with head gaskets, its a widespread problem. If the smoke is white and smells sweet it is coolant leaking into the pistons via a head gasket. Replace the head gasket before it fails. If you blow the head gasket it will ruin the engine.

Cam Seals

It is most likely the cam seals dripping small amounts of oil onto to the bottom of the engine block. When the engine warms up, it will burn the oil off.

Oil Pressure Switch

It could also be the oil pressure switch (oil pressure sender) leaking oil. This is the sensor that looks like a large bolt with a single wire attached to it located underneath the alternator at the front top of the engine. Watch it closely while the engine is running for an obvious leak. Much more easily resolved than the above possible problems. Also check to make sure that the oil pump is not leaking. Oil can drip down from the oil pump and burn which would create smoke.
