Plant used Prolong AFMT and EP-2 Grease, which improved bearing life. Their reduced energy costs have been realized in virtually all applications. Their pulverizors had an immediate amp drop of 5-15% after treatment with AFMT. Noise levels were reduced markedly with speed reducers after an addition of only 3-5% AFMT. Prior to the application of Prolong, vertical pumps suffered continual loss of bearings. Furthermore, the plant has had continued benefits from the application of Prolong products in the following areas: Babbited bearings, boiler feed pumps, water pumps, air preheaters, reciprocating air compressors, fluid drive couplings, fans, …

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…

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…

Boeing’s use of Prolong Ultra Cut for machining applications has had positive results. Prior to addition of Prolong’s Ultra Cut 1, they could not get one 10″ deep hole completed with a drill lasting the entire hole. Using Prolong, they could complete six holes per drill- Applied by misting, not flooding. Further, metal-cutting saw blade would squeal and make all kinds of racket and chatter. With Prolong they now have a very quiet result. The Boeing Company

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.

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 …
Research scientists at Northwestern University, sponsored by the Infrastructure Technology Institute, conducted a laboratory project “to study the effect of various lubricants on the wear and corrosion of metals recommended for bridge pin and eyebar connections”. Scientists ran corrosion tests in a salt fog chamber to replicate the environmental conditions United States bridges are exposed to. They used several types of metals and 7 competitive greases in their testing. Findings are as follows:
- “Prolong EP-2 gave an exceptional reduction in corrosion rate”
- “Results show Prolong EP-2 Grease to be about 10 times more resistant to corro…
I was using Arco gasoline in my Buick LaSabre (2000), as a savings option. My engine began to foul and the check engine light eventually came on I returned to the dealer and was informed that there is some particular additive in the Arco gasoline which is not compatible with the GMC injectors… the problem was addressed. Performance had not returned however, so needless to say I had been disappointed. When you sent the injector cleaner I felt anything would be worth a try. I followed the directions and I must say that I am most impressed with the product. The engine performance has returned as though it was new and the mileage has improved dra…

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…
