Gasoline coming out from the refinery is usually clean. Before getting to the gas station however, it has been transferred through a complex network of wagons, trucks and storage tanks where water, sediments and other contaminants took advantage of adverse conditions such as bad weather, poorly cleaned hoses, damaged caps, seals and gaskets or insufficient handling precautions to make their way to your fuel.

Left overs at the bottom of the tank, hot weather condensation and the winter time formation of ice crystals also constitute major sources of fuel contamination.

In these conditions, even the most reputable suppliers can’t guarantee that the fuel they just delivered to your station is 100% contaminant free, therefore, you should consider testing your gasoline after each delivery.

Testing your gasoline before using or selling it is a low-cost precaution against engine failure and breakdown as well as a proof of compliance with the Government laws and regulations.
