  How to Report If you experience problems after purchasing fuel or if you believe you did not get the amount of fuel you paid for you should call our office at (303) 318-8500 or (303) 318-8507, to file a complaint. Please provide us with the facility name and address, date the product was purchased, the type, grade and volume of product purchased, the pump number, and specific engine symptoms related to use of the product purchased. This will help the laboratory focus on analysis specific to the symptoms. It is very important that your call be made as soon as you recognize that you have a problem, as some stations receive deliveries of new fuel products on a daily basis. Your timeliness in reporting is important, as it determines whether our inspectors can obtain representative samples of the same product that po-tentially caused you a problem.
