What Causes a Burning Oil Smell?
Before we dive into the solutions, it’s essential to understand what causes that burning oil smell in the first place. There are several reasons why your car might be emitting this unpleasant odor, and we’ll explore some of the most common causes below:
Worn-out Engine Gaskets
Over time, engine gaskets can wear out, causing oil to leak onto the hot engine components, resulting in a burning smell. This is especially common in older cars or those with high mileage.
Oil Leaks
Oil leaks can occur due to worn-out seals, damaged engine components, or improper installation of oil filters. When oil leaks onto the hot engine, it can burn off, releasing that characteristic smell.
Dirty or Clogged Oil Filter
A dirty or clogged oil filter can restrict oil flow, causing it to build up in the engine and eventually burn off, resulting in that pungent aroma.
Low Oil Levels
Driving with low oil levels can cause the engine to overheat, leading to a burning smell. This is especially common in cars with manual transmissions or those that are driven in extreme temperatures.
Bad Oil
Using low-quality or expired oil can cause it to break down prematurely, leading to a burning smell. This is especially common in cars with high mileage or those that are driven in extreme conditions.
Engine Problems
More serious engine problems, such as piston ring wear, valve stem seal failure, or engine block cracks, can also cause a burning oil smell. These issues often require professional attention and may be more costly to repair.
