The most common operational failures experienced by diesel-powered Vehicles, equipment and generators are fuel related. There are millions of gallons of older stored fuels that will not meet minimum ASTM standards for use. A large percentage of them are discarded as unusable. We have developed new methods to restore/rejuvenate those fuels for 20-40% of the typical replacement costs.

(40% of tested fuels, stored 1-year or longer, failed to meet engine manufacturers minimum specs for warranty)

Ø Exercising your vehicle, equipment, diesel generator once a week/month won’t solve the problem!

Ø Using a biocide additive alone won’t solve the problem.

Ø Adding an on-site fuel-polishing unit alone will not solve the problem.

  • After a full summer of ethanol gas problems I finally found a product that stopped them and made my engine run like it is suppose to. I will never use anything but Gas-Shok from now on.

  • I had my tank cleaned by USA Fuel Service, they save most of the old fuel for me and the Desl-Shok product has stopped my problems with water and algae. The black smoke disappeared and I use less fuel. Bottom line is it works!

  • I was surprised to find USA Fuel Service had the answer we needed to solve ethanol fuel issues for our customers. We use their exclusive system in our shop to clean tanks and their “Gas-Shok” product has proven to be the best fuel additive to prevent future problems after we are done. It works great and our customers love it. Thanks, Tim

  • Hi, Just wanted to say how thankful I am now that my boat runs the way it should. I have been experiencing fuel starvation problems, particularly when mooring the boat in tight spots after a long day cruising. I'm no longer stricken with anxiety from a boat engine stalling when I need it the most! Thanks again!
