Testimonials

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 …

Your Product (Prolong Super Heavy Duty Oil Stabilizer) has impressed us. It has performed very well on one of our vehicles that was on its way some costly repairs. We added your product and it improved The engine performance greatly, and has also reconditioned the seals of the manifold which has reduced and almost stopped the leak, this has avoided expensive repairs. We deal with the agriculture community and your product might be of great benefit to their tractors. We would like to send them information on your product. Please let us know if this would be of interest to you. And the possibility of perhaps distributing your product to our cus…

Gold mine had been having problems keeping cooling tower gearboxes at acceptable temperature levels. Temperature on 5 gearboxes was 58 degrees C standing in open air. In an open space, the weather plays a big role. They treated the gearboxes with AFMT after which the temperature dropped to 43 degrees C. By using Prolong in these 5 gearboxes and all 5 showing a temperature drop of 15 degrees C, this showed conclusive evidence that Prolong took away the friction in the gearboxes, which resulted in a 35% drop in temperature.

I have an1989 Eldorado, that just recently developed a huge slip in my transmission. I thought I was going to have to spend a great deal money for either a new transmission or have mine rebuilt. With money being an issue right now, I went to my local auto parts store, look though the transmission lubricants, and saw your product on the shelve. It was the most expensive one there. I deliberated for some time, when finally I thought I would give it a chance. It seemed to have an immediate effect on the transmission. The Prolong lubricate as been in for about a month now, and with each week the transmission has only gotten better. I do not know …

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…

Steel mill had a pillow block bearing running at 326 degrees. Normal operating temperature was 190 degrees. The fourteen-year old bearing was smoking, but they had to keep production going until the morning when maintenance could fix it with new parts. They used EP-2 Grease and twenty minutes later, the temperature had dropped to 260 degrees, the smoking and squealing had stopped. Through the night, the temperature had dropped to 130 degrees and leveled out at 167. Steel Mill in Ohio

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…

Good morning Sir or Ma’am, I have been a loyal customer and a believer in your product. I once had an old Dodge truck that I had put your tranny and engine treatment in and it was amazing. I drove it up to and over 500,000 miles. when the tranny blew on it and I mean dumped the fluid all over the road, it still drove and made it all the the way to the tranny shop at normal operating speeds. When it was taken apart by the mechanic, he was shocked to see no clutch pads and he said that it should have never made it this far. It was amazing and becuase of that I am a believer in your product. Thank you very much to take the time to read this emai…

We have been using Prolong products for approximately two years. We have had excellent results in applying Prolong AFMT in preventative maintenance in gearboxes on HPM injection molding machines, Sargeant vacuum pumps, 1,000 gallon capacity hydraulic systems and countless other plantwide procedures. I rate Prolong products superior on all counts. F.D. Helman, Maintenance Supervisor, Worthington Industries, Inc, Salem, Ohio Manufacturers of injection molded plastics

We just wanted to let you know how much success we’ve had using your product. We have a hydraulic grout pump that gets up into the 200-degree temperature range during pumping. Over the past 17 years that we’ve been in business, we have consistently had the same overheating problem with our pumps. We have tried everything, even going so far as to install an external cooling system, but with no good results. Prolong has really helped. We added 4 gallons to our pumps 45-gallon reservoir and your product actually dropped the operating temperature of the oil by 50 degrees! We would highly recommend Prolong in any hydraulic system. Art Methey, Vic…
