A burning oil smell usually means oil is leaking onto the hot exhaust manifold or being burned in the combustion chamber. Most causes are not emergencies, but every cause should be fixed - oil starvation can wreck an engine.
You can keep driving for now, but check your oil level weekly until you fix the leak. If the dipstick is more than a quart low, top up immediately and get the leak found before it becomes engine damage.
The most common oil-on-exhaust source. As the gasket ages it lets oil weep out the top of the engine, where it runs down onto the exhaust manifold and burns off.
Oil drips from below onto the exhaust pipe further back. Check for oil drips under the engine after parking on cardboard overnight.
Worn piston rings or valve seals let oil into the cylinders. Smell comes from the exhaust along with bluish smoke. Engine uses more than 1 quart per 1,000 miles.
An overfill pushes oil out through the PCV system and onto the engine. Check the dipstick - oil should be between MIN and MAX marks.

Oil spilled on the manifold during a change. The smell will fade after a few heat cycles. If it does not fade in 1 - 2 weeks, the source is real.

Yes, for short distances and as long as the oil level stays above MIN on the dipstick. Check it weekly. Running an engine low on oil is what causes the expensive damage, not the smell itself.
$150 - $400 on most cars. Higher on engines where intake parts have to come off (BMW N20, some V6s). The part is cheap; the labor varies wildly.
Almost always residue from a spill during the change. The smell fades over 3 - 5 drives. If it does not, return to the shop - they may have over-tightened or cross-threaded the drain plug, or used the wrong filter.
Usually no - most causes are gaskets or seals. But if you are adding more than a quart of oil every 1,000 miles, that is internal oil burn (rings or valve seals) and worth a compression test.
Not directly. The smell itself does not. But the underlying problem (low oil pressure, leaking PCV, etc.) can trigger P0520, P0521, or P0524.
As long as you keep the oil topped up, indefinitely - but the leak will get worse, ruin nearby parts, and the eventual fix will cost more. Most owners fix it within a month of noticing.
