We realize how and why the public is so skeptical about fuel additives. They have been misled by false claims and wasted money on mediocre low strength products for years. However we prove ours works by using them ourselves in our business every day.

We are a large professional tank cleaning company that specializes in cleaning tanks and restoring fuels with ethanol issues. We have over 40 years experience and have blended fuels and booster additives for H.P. and lubrication for use in fuel drag boats, tractor pulls, motorcycles and offshore racers. Originally we developed additives strictly for our own use. However, in recent years our tank cleaning clients were so astounded by the superior results of our professional tank cleaning/fuel restoration service they demanded access to the chemicals we use.

We have now begun making them available to the public through our dealer network. They discovered our industrial strength state-of-the-art additives prevented water issues in ethanol blended fuels, added MPG, reduced smoke/emissions, added lubrication and stabilized fuel 12-18 months. It’s simple, if they didn’t work our tank cleaning company would be out of business.

Unlike other additives we do not add dangerous explosive chemicals to boost the fuel and we do not use alcohols or derivatives. Our “GAS-SHOK & DESL-SHOK”™ products are a blend of several highly modified pure petroleum ingredients that work by changing the molecular structure of the fuel.

To explain it in simple terms we dramatically increase the ability of the fuel to absorb more oxygen during the high heat created during the combustion process. Therefore you are burning 10-20% more of the fuel and losing less of it out the exhaust. The fuel actually produces more horsepower, MPG and less smoke and pollution from each gallon of fuel.

In addition we add stabilizers that prevent water issues and concentrated synthetic lubricants that will typically double the life of your fuel pump and injectors which can save you thousands in down time and maintenance.

  • 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!
