“Hey there I just wanted to say thank you , for ,you might ask well I have been using your products in many of vehicles, that are under a lot of abuse. Demolition derbys , trucks and also cars . I run a 318 that has been gone through and added many extras . I can say your products do things that are truly amazing . The motors never get hot and if they do they will stay running until you hit the switch to shut down. I was wondering if you guys could send me some stickers to get your name out there to help you guys out. You have done a lot for me so by putting your name on my vehicles would be a honor. Thanks again.” Derrick H., Sleepy Eye, MN…

I would like to give you a very positive report on your Prolong Ultra Cut 1 water soluble cutting fluid. We are in the process of drilling and tapping 1045 Forge steel at 50 surface feet per minute. With your product, we have doubled our tool life from 600 pieces to 1200 pieces. We are also very pleased with the cleanliness, workability, and odorless quality of this product. Thank you. I would recommend this product to any company that has a need for cutting fluids”. J. Downing, President M.U.P, Inc.

After seeing your impressive demonstration of your Prolong products, we made the decision to test it in our truck #53, which is a Cummins with 552,433 miles and a 12315 transmission. (We used Engine Treatment in the crankcase, Transmission, Gear & Differential Treatment in the transmission, front differential and rear differential, and AFMT to each of the front wheel hubs. We then applied Diesel Conditioner to 200 gallons of diesel fuel). After the first week of travel, which was about 7,000 miles, the test results showed that the mpg went from 4mpg to 5mpg, an increase of 25% in mileage, or an additional 200 miles per fill-up. The driver of …

Plant operating hydraulic bandsaws tested product in place of existing fluid. Saw-blade life was measured, as well as annual cost of blades. Previous saw operation was 35 cuts per blade at an annual cost of $1,500,000. With Prolong Ultra Cut 1, the saw operated 50 cuts per blade at a savings of $450,000 annually.

When introduced to Prolong Waterless Wash & Shine, I was very skeptical of it’s claims…I could not imagine not using water to clean my car. I did give it a try, based on hearing how good it was. I am a believer! I have used the product in the shade, in scorching sun, in the garage, and every time, I get a beautiful shine, reminiscent of a good wax job, without the annoying build-up. I have used it as a touch-up when my wife parks under a tree, and it works on chrome, paint and the painted plastic accents on my truck. Though the Prolong website FAQS call for terry cloth towels, the microfiber cloths sold at Harbor Freight also do a …

I bought a full size Chevy truck in 1991 with 39,000 miles on it. Today, I have 520,000 miles on it! We have been using Prolong engine and transmission treatment since and have never had any engine problems. Our transmission went out at 100,000 miles. When we had it replaced, we put the transmission treatment in. We were driving down the freeway when the transmission started to free wheel. We found one of the hoses was broke. We replaced it and went on our way. Come to find out the transmission line broke at my house about 120 miles from where we stopped. The transmission has lasted 400,000 miles and my truck is still running as strong as eve…

Had to write to tell you of some amazing success I had with Prolong Transmission Treatment. I have a 1993 Chrysler Intrepid. I started having trouble with the transmission, the car would stick in 1st gear. Shutting the car off and restarting would correct the problem. This happened about once a week for about six months, then it was happening every time I stopped. I replaced the control module, but it didn’t fix the problem. Next I changed the oil and filter… still no improvement. It was going to cost $2,000 to replace the tranny and I debated spending that much money on a car with 280,000 kilometers. Purely by accident I saw Prolong at Wal…

Plant operating a leased fleet of 42 “5-year throwaway” lift trucks, was experiencing so many gearbox failures, downtime and repair-related issues, that they decided in the third year of operation to install 10% Prolong AFMT into each truck. Their desire was to “get through” two more years before having to discard these trucks for a new leased fleet. The fleet is now in its ninth year of operation and running so well that, in the eighth year, the entire fleet was purchased. Automotive part assembly plant.

I use your products in all of my vehicles and even my Cub Cadet lawn tractor and snow blower anything with an engine gets it-. I have a 1993 Honda Civic that I purchased brand new with 4 miles on it and I am pretty good about changing the oil and fluids regularly. -I had been using expensive synthetic MOBILE 1 oil and even tried using a competitor Duralube back in 95-97 from mile marker 68,419 to 102,700 miles until i saw your infomercial with a red Viper running around a track without oil. I purchased my first treatment on JULY 18 1998 about 14 years ago and have been using it ever since- I now have 418,800 miles on my civic and although…
