"I used DSX Extra in my engine, differentials and DSX Defender II, the protective wax, on the exterior of my cab. I am extremely happy with the results from both products."

"I have now been using DSX Extra in my engine for approximately 113,000 miles. The MPG ranges from 5.5 to 6.0 since adding DSX Extra and using DSX Defender II."

"I decided to apply DSX Extra to the front and rear differentials of my truck. Temperatures in the front differential, prior to application, ran approximately 190 degrees and the rear approximately 180 degrees. Now temperatures are approximately 170 degrees (front) and 160 degrees (rear). Lower temperatures are a direct result of less friction, which results in extending the life of major components."

"With today’s rising cost of equipment and repairs, extending equipment life is a bonus that adds to profits."

"You told me how good the DSX Defender II wax was and what I should expect. To be fair, I did not believe any product could be that good."

"I applied the DSX Defender II to the cab, glass and mirrors as instructed. My first application did not include the stainless steel. The shiny appearance was very impressive. The big surprise came when I washed the bugs, bird dirt, etc., off the truck at the end of the week, with a simple spray from the garden hose. A job that normally takes an hour each week was done in minutes."

"In late February and March we drove in freezing weather with snow, ice and extremely windy conditions. NOTHING STICKS!"

"Even the salt solution used on icy roads washes off easily, if washing is needed. I believe DSX Defender II is important as a safety factor, because the glass, windows and mirrors, are so clean and easy to keep clean."

"The DSX Products are saving me money everyday. My next order for DSX Products is in the mail".

"I evaluated DSX products for about 6 months by adding DSX Extra to the engine lubricants."

"The engine runs quieter with DSX Extra than without. It seems to run cooler, appears stronger. There was an overall slight increase in fuel mileage."

"Prior to using DSX products I would add 4 to 6 gallons of oil between changes. After using the DSX Extra I add 3 to 4 gallons of oil. Remember the engine already had over a million miles on it before I began using these products."

"Comparing fuel used at idle I would consume 1 1/2 to 2 gallons per hour. I now burn about 1 GPH. I consider this a significant increase. I have also noticed an increase of oil pressure while at idle and the engine idles cooler."

"Recently I cleaned the fan and applied DSX Defender II to the blades. The fan appears to cool more efficiently, and the blades have remained clean."

"Individually, things like this have a small effect on vehicle performance, however. collectively they can have an enormous impact on vehicle performance and operating costs."

"About two months ago a heater hose failed when pulling a full load In the mountains of Utah. Road conditions did not allow for stopping, so I pulled on up the hill until I could safely get off the roadway.............I have noticed no damage to the engine. I believe the DSX Extra helped prevent serious internal damage to the motor."

"The economy of diesel improve 6.45 MPG to 7.54 MPG in each 15,000 miles obtaining an improvement of a 17%."

"With my second camion, a Kenworth with motor CAT 3406, I have used EXTRA DSX for 210,000 miles. The use improved diesel engine from 6.0 MPG to 7.0 MPG almost immediately. This is an improvement of 16%."

"In both trucks, the oil consumption between the oil changes has lowered, also the used oil is remarkably clean in appearance and when touching. Before using DSX EXTRA it was extremely dirty bright oil and without viscosity."

"I also use DSX DEFENDER II to give the protective brightness to both trucks. A bottle is very effective and lasts of four months. Both trucks always shine well and at night it is easy to see since the lens is clean and I can see with greater confidence since nothing adheres to the lens because this product helps to repels the insects."

"I will continue using the DSX products since they are helping to extend the life of my trucks."
