Contact Motor Fuel Quality Testing

The Comptroller's Office routinely tests the quality of motor fuels sold in Maryland. If you have a question or complaint about fuel quality, call 410-260-7388.

Maryland's testing program checks fuel quality at all points along the distribution chain, and stops the sale of fuel that does not meet accepted quality standards. The comptroller maintains a petroleum testing laboratory, which is consistently recognized as a leader in its field. Samples representing about two billion gallons of gasoline, diesel fuel, home heating oil, and other fuels are tested each year. Only about 1 percent of the fuel tested is found to be substandard.
