If you experience problems after purchasing fuel or if you believe that you did not receive the amount of fuel for which you paid, you should file a consumer complaint or call the OPS Petroleum Laboratory complaint line at 303-866-4967.
Timeliness is very important, so you should call as soon as you recognize that you have a possible fuel quality problem.
The amount of time between when you purchase the fuel and when you file a complaint will determine whether an OPS Oil Inspector can obtain a representative sample of the same product that potentially caused you a problem.
Please provide OPS with the following information:
This will help the laboratory focus on analysis specific to the symptoms. Gasoline and Diesel fuel float on top of water, so water remains at the bottom of the storage tank until it is physically removed.
