Warning Signs

Does my fuel storage system have Bugs? 

To determine if the fuel storage system has bugs a sample of the fuel needs to be pulled from the bottom of the tank. Typically Bugs Diesel Brochure 0315.inddthis is performed using a device called a Bacon Bomb or fuel thief as shown.  The sampling device should be properly cleaned prior to collecting the tank sample to avoid cross contamination of the sample.

Some of the fuel will be used for the Microbial Cult test and the remaining fuel may be used to perform cold filter plug point, pour point and cloud point tests. Contact your Penray Fuel Doctor to explain the process and schedule a fuel sampling appointment.

Warning Signs:

In addition to the fuel sample analysis, several Bugs Diesel Brochure 0315.indd
symptoms may indicate a problem. Examples include slow flow rate from the dispenser, clogged dispenser filters, sulfurous odor (rotten-egg), leopard type spotting on a fuel filter and slime coating on metal parts or blistered hoses. If any of these symptoms are present the fuel storage system is no longer healthy and requires immediate attention.

How are the bugs killed?

Biocides are regulated and registered by the EPA. Biocides are designed to kill and control bacteria, fungus and mold in fuel. They only address problems with living organisms in the fuel storage system, biocides do not address problems associated with oxidation that lead to sediment and gum. Penray’s Fuel Prep™ Biocide is an EPA registered biocide and is used to kill and control bugs in the fuel storage system. Unless there is a severe amount of sludge already present, after treatment with Penray Fuel Prep™ 90% of the bugs will be killed within 6 hours. The dead bugs will fall to the bottom of the storage tank and should be removed with the water to prevent additional fuel filter clogging. To prevent the growth of new bugs, regular treatment with Penray Fuel Prep™ Biocide several times a year and regular checking and removal of water is recommended.
