Are you experiencing a strange smell of oil in your car? If yes, then you are not alone. A lot of car owners are often puzzled when they notice an oil smell in their car. The primary reason for this is that there are several reasons why you might smell oil in your car. In this article, we will explore the common causes of oil smells in your car and how to diagnose and fix them.
Common Reasons Why You Smell Oil in Your Car

Worn Out or Damaged Engine Gasket
An engine gasket is a seal that keeps the engine oil from leaking. When the gasket is damaged or worn out, it can cause oil to leak, which can result in a strong oil smell. If you suspect that the engine gasket is the cause of the oil smell, then you need to have it checked and replaced by a professional mechanic.
Oil Leakage
Oil leakage can also cause a strong oil smell in your car. This can occur due to several reasons, such as a cracked oil pan, damaged oil filter, or loose oil cap. If you notice oil spots on the ground after parking your car, it could be a sign of an oil leak. Have a mechanic inspect your car to identify and fix the issue.
Overfilled Oil Tank
Overfilling the oil tank can cause oil to spill into the engine, resulting in a strong oil smell. This can also cause damage to the engine if the oil level is too high. Make sure to follow the manufacturer’s recommendations for oil levels and have a mechanic drain any excess oil if necessary.
Oil Filter Issues
A clogged or damaged oil filter can also cause an oil smell in your car. The oil filter’s primary function is to remove impurities from the oil before it circulates through the engine. If the filter is clogged or damaged, it can cause oil to accumulate and produce a strong smell. Have the oil filter checked and replaced if necessary.
Oil Spillage During Oil Change
During an oil change, oil can spill onto the engine or other components, causing a strong oil smell. This can happen if the oil drain plug is not tightened correctly, or the oil filter is not installed correctly. Make sure to have your oil changed by a professional mechanic and check for any oil spills afterward.
Engine Overheating
If your engine is overheating, it can cause the oil to burn and produce a strong smell. This can be caused by several factors, such as a malfunctioning cooling system, a damaged radiator, or a faulty thermostat. Have a mechanic diagnose and fix the issue to prevent further damage to your car.
