What causes sulfur odor in the exhaust?
A sulfur odor emitted from the vehicle's tailpipe does not necessarily indicate that there is an issue with the engine's running condition. It is most likely directly related to the fuel.
Sulfur is a natural component of crude oil from which gasoline is refined, and the amount of sulfur can be decreased through the refining process. While the amount of sulfur in fuel sold in California is regulated, gasoline sold in other states can have substantially higher sulfur content. Sulfur content may vary between gasoline brands and locations; switching gasoline brands may help. The more sulfur present in the gasoline, the stronger the sulfur odor can be.
In order to properly assess your vehicle, we recommend you contact the Customer Relations Manager at your local dealer.
