If the oil is overfilled can you let it burn off?

The answer is always NO NO NO NO Nope, easiest way, would be to get some tubing from a hardware store (an icemaker tubing kit "may" work), and a syringe. Remove the dipstick and attach the tubing to that port. Attach the syringe and proceed with "sucking out" the oil into a proper oil holding container, checking the oil level, and repeat if necessary. Oil over-fill may result in increased MPG, splashing oil onto the engine, and other problems if droven for long periods of time under those conditions, which is why I always check my oil every 3rd fill-up atleast (about once a month).
