If you feel a burning oil smell coming from under your car’s hood, it could possibly be because your car has started to overheat owing to a shortage of oil. As your engine uses up the remainder of the oil in your car, it’s going to start to burn it off, which can cause a burned smell. This is a situation in which you should absolutely not disregard the smell. If nothing is done, it could lead to your engine catching fire in the near future.

It could malfunction and stop displaying the engine temperature. Also, you should be on the lookout for any smell of burning in the air. They may provide you with all the information you need regarding the state of your engine.
If you notice any of the signs mentioned above, simply head straight to a professional mechanic to fix the problem.

Most of the time, if you find yourself wondering, “Why does my car smell like burning oil after driving?” it will be because your car is actually burning oil.

How to fix
Whenever you notice that the gears in your gearbox are hotter than they should be and may be on the verge of failing, simply go to a professional mechanic to fix the issue.
Transmission fluid leak

A transmission fluid leak can plainly result in less transmission fluid than should be present in a transmission system. It might deplete the transmission fluid required by the gears and cause them to emit a burning oil smell. Pay attention to this smell and try to determine its origins. If this is caused by a transmission fluid leak, you will need to have it fixed immediately.
How to fix
If the issue is a transmission leak, a simple reseal service and transmission fluid flush are sufficient to resolve the issue. Nevertheless, if your transmission is significantly damaged, you will most likely require a replacement transmission for your car.
