The Risks of Motor Oil Exposure

Motor oil is a vital component of any car’s engine. Unfortunately, motor oil is also a risk-laden substance. If you are a mechanic, please know that exposure to motor oil has been known to increase the risk of contracting several medical conditions. These conditions include:


Contact dermatitis is a skin allergy that occurs when the skin is exposed to an irritant (in this case, motor oil). The reaction is more of an annoyance than a cause for concern, although it is possible that long-term dermatitis can cause wounds and infection due to constant scratching.


A study from Sweden has shown that exposure to motor oil can increase the risk of rheumatoid arthritis. This condition causes painful swelling in the hands and feet, limiting one’s range of movement and ability to use the affected body part(s) properly.

Skin Cancer

Used motor oil has undergone chemical changes and has picked up impurities and toxins along the way. When used motor oil comes into contact with skin cells, these impurities and toxins can damage the DNA within skin cells. If this happens often enough, skin cancer is a possible outcome.

Of course, the risk of contracting these conditions is tied to frequent and long-term exposure. The best way to avoid these risks would be to wear gloves while working. If you still insist on working with your bare hands, be sure to invest in effective hand cleaners from trusted brands like Gojo.
