2001 Oldsmobile Bravada engine running hot

oil will go down while the car is running because it is being distributed throughout the engine, but when you turn it off the oil drips back down into the oil pan. but you should still make sure your oil is up to the proper level. unfortunately there are idiots working in these places and some even forget to put the drain plug back in and have ruined many of engines. not saying they all are. but we have the final responsibility. to oversee our vehicles. any other questions, feel free to ask. also please clear up the statement about your vehicle being "hot" I dont think I understood you clearly.
