Program background
In 1997 Oregon adopted the American Society for Testing and Materials (ASTM) national standards for motor fuel. The adoption of these national standards, along with state motor fuel quality laws, established the Division´s Motor Fuel Quality (MFQ) Program. The Measurement Standards Division tests the quality of gasoline and diesel products sold within the state of Oregon. Loading terminals, jobbers, and motor fuel retailers are all subject to inspection by the Division.
 
Through our MFQ program and meter inspection, we work to ensure that consumers and retailers alike receive the quality and quantity of fuel products purchased.
Fuel complaints
Picture of a consumer fueling their vehicle.
Submit a complaint form online if you think that
  • you did not receive the correct quantity of fuel that you were charged for.
  • you purchased fuel that was sub octane, contaminated with water, or was of poor quality in some other manner.
  • a station was incorrectly advertising and/or pricing their fuel.

A division field inspector will investigate your complaint and inform you of the results. 
 
Please be advised that this complaint will become part of our permanent records. Complaint forms are subject to Oregon's Public Records Law and may be disclosed to persons who request to review its contents. As such, it may be released to the business or person about whom you are complaining, members of the public, or other agencies if requested.
