If your car has a hot oil light, it means that the engine is running low on oil. The light will come on when the engine temperature gets too high. This can happen for a number of reasons, including:
-The oil level is low and needs to be refilled.
-The oil is old and needs to be replaced.
-There is an oil leak.
-The oil filter needs to be changed.
If you see the hot oil light, you should pull over as soon as possible and check the engine oil level. If it's low, add more oil until the light goes off. If the problem persists, have your car checked by a mechanic.
