Oil was changed in April. It seems the oil is over the hash mark sometimes, but overfill light is not on. Is oil supposed to be checked cold or hot? Gas pump didn't shut off overfilled, car smell like gas, opened back panel found a fuel line laying in bottom of fender, feels like a pad at the bottom of well, car smells like gas all the time, any ways to neutralize the smell and is the hose supposed to be connected to a tube to exit vehicle
