Testimonials

Gold mine’s initial problem was that a set of bearings had score marks causing the operating temperature to rise and no replacement bearings were available for approximately 2 weeks. They turned the white metal bearing caps around, i.e. top to bottom, cleaned the old grease and contamination out, filled with Prolong EP-2 Grease and ran for 4 weeks until a scheduled repair could be done with new bearings. They only run on EP-2 now, but use far less for longer than the old type of grease with better bearing life. Gold Mining Group, South Africa

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 have believed in your A.F.M.T for 21 years. I actually went to your shop and met the guy who came up with it. Anyway, I was never able to convince my father to use it, but I do. I own a rock crushing service in Corona, California. I always buy your engine treatment and dump it into failing equipment. (I do put it into my own vehicle normally) Back to dumping it into my failing equipment. I have had 3 situations where replacement was the real fix, but I tried Prolong to avoid major downtime and cost. All I did was dump a bottle in, and like magic all three units have been running without missing a beat. We are talking about large, high speed…

The Prolong Water Soluble Ultra Cut 1 Cutting Fluid, when compared to our best water soluble oil, has proven to last over five times longer. This product has also extended tool life over 30% and significantly reduced operator adjustments normally required for compensation of tool wear. This product has also offered exceptional rust inhibiting protection of parts subject to a hot and humid environment. Product was applied to carbon steel test samples that had one side with a ground finish and then placed outside in the rain for five days, and then placed indoors for over one month. The results have been excellent. Each sample showed minima…

I have used and promoted Prolong since I saw your infomercial, before you could even buy it in stores. I’ve been extremely happy with all your products. I could tell you about things that impressed me like after 25,000 miles with Prolong Transmission Treatment, I took it to my mechanic to change the filter and transmission fluid. He said that in all the time he has changed the fluid with me using the product there has never been any fine grindings in the pan, which to me means no wear. W. Maurer, Saint Helen, MI

I want to say I use Prolong in all of my vehicles and I will not put no other treatment in them. I use from your engine treatment to your trans. treatment and not even once haves it ever let me down. I greatly thank you and I will always use Prolong. Sincerely, Tim B., Dillwyn, VA

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. G. Schultz, Foreman, Kloof Gold Mine, Africa

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 two samples of grease were tested by the South African Bureau of Standards, Prolong Super Lubricants met or exceeded all of their test criteria. Properties tested by SABS were as follows: Penetration, copper corrosion, drop point, evaporation loss, oil separation, rust prevention, water wash-out, wheel bearing leakage, working stability, Timken OK-value, and wear scar diameter. South African Bureau of Standards, South Africa

First, let me say that I have a 1996 Dodge pick up with a Cummins Diesel. I have used your oil and transmission additives since I bought this truck new, and I now have 235000 miles on this truck, which is low for the engine but the transmission should have died miles ago. This truck has towed everything from snowmobiles to fifth wheel campers from coast to coast and hauled loads it shouldnt have. I attribute the longevity of the transmission to your product. I have used it in other vehicles and have had the same luck with your engine and transmission products. David Switzer, North Carolina
