Most cars need different fluids for the engine to work well. Among these important and essential liquids, we can mention car engine oil, gearbox oil, etc. However, some people have encountered a problem, which is the smell of burnt oil. You may smell the smell of burnt oil inside the car cabin or from the car heater, for this purpose, in this article, we have investigated the "cause of the smell of burnt oil inside the car cabin" or the smell of burnt oil from the car in general, so that you know what the problems are. They cause odors and how to fix them
The cause of the odor of burnt oil from the machine
Low level of engine oil
Oil is very important for lubricating the moving parts of your car, that's why it is recommended to use the best engine oil and in the recommended amount. If your car's engine oil level is too low, there is a good chance that the lack of oil is causing the smell of burnt oil in your car. This is because your car is trying to use the remaining oil, so it burns the remaining oil in the engine.
Excessive heat of the engine
Overheating of the engine is another common reason for the smell of burnt oil in cars. In general, engine overheating can be caused by many factors, but the most common reason for engine overheating is that there is not enough oil in the engine. This issue can be very dangerous because if this problem is ignored, there will be a lot of damage to the engine.
Lack of gearbox oil and other oils
In most cases, the smell of burning oil is caused by the lack of other fluids, including gearbox oil. As you know, gearbox oil is necessary for your car because it lubricates the moving parts of the gearbox and at the same time creates friction and hydraulic pressure for the internal parts to work. Typically, a lack of transmission oil can mimic the smell of burnt oil, especially if there hasn't been enough fluid for a while. If there is not enough gearbox oil, the car's gears will move with difficulty and eventually create a burning smell similar to burning oil.
Oil leakage
In addition to a lack of oil, an oil leak can also cause your car to smell like burnt oil. When the engine oil or transmission oil leaks, it is poured on the hot parts of the car, which causes the moving parts to move with difficulty and finally the smell of burnt oil is created.
Leakage in oil block washer
Another main reason for the smell of burning oil, oil leakage and one of the most common places where oil leakage occurs is the block gasket or oil holding tank. This gasket closes the engine block or oil tank so that oil does not leak out of the car. However, when the oil block gasket is damaged over time, it causes oil leakage and a burnt oil smell.
Problem with crankshaft sealing
The crankshaft is a part of the internal engine that protrudes slightly from each side of the engine, and each end of the crankshaft has a seal to prevent oil leakage. However, crankshaft seals are not without problems as they can eventually break or wear, resulting in oil leaks and causing your car to smell like burnt oil. As such, you should evaluate both crankshaft seals to see if there is a gap for oil leakage.
