i have noticed that if I check my oil when the engine has just been shut off, I will show it being low about 1/2 qt. But if I check it in the AM, its normal.
Syntheic oils can hang up for some time and you may not get an accurate reading. If its a 1/2 qt low, I would not top off untill I checked it cold to see.
Also, some oils are more volatile, will burn off (from the heat of combustion not past the rings) a certain amount right away and then stablize. Pertroleum oils are good for this but Mobil 1, I have not idea but could be the case.
