Sulfur In Gasoline
If you live in the northeast United States, you r vehicle
may have been designed to meet California low emission
stand ard s with clean burning, low sulfur, California
gasoline. Gasoline sold outsid e of California is perm itted
to have higher sulfur levels which may affect the perfor-
mance of the vehicle’s catalytic converter. This may cause
the “Malfu nction Ind icator Light” to illuminate.

contain effective detergent additives. Use of additional 5
detergents or other additives is not need ed und er norm al

gasoline does not necessarily mean you r emission control
system is malfunctioning. The manu factu rer recom -
mend s that you try a different brand of unlead ed gaso-
line having lower sulfur to determ ine if the problem is
fuel related prior to retu rning you r vehicle to an autho-
rized dealer for service.
