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.

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

One of my vehicles is a ’92 Suburban with an odometer reading of 285,000 miles. Since discovering Prolong products, six or seven years ago, I have used both your Engine Treatment and Transmission Treatment religiously. In the past two years I have also used your Injector Treatment and Fuel System Cleaner each Spring and Fall, as well. The results are so amazing that a note seemed in order. The original automatic transmission is continuing to shift smoothly as designed. My mechanic friend is extremely impressed by the engine and transmission performance. J. Jacobson, New Brighton, MN

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…

About 12 years ago i bought a 1992 dodge dakata 4×4 with a 3.9 v6 with 87000 miles on it. I had seen prolong used at the race track in town here and thought I would try it in my truck so i bought some and have been using it ever sence on everything i drive I still have the truck i just turned over 240,000 miles everyone laughs at it cause it rattles alot I run 20w50 and prolong in it all year long it’s so loose i can just about turn it over by hand without using a wrench I just put a new trans it and started using your trans lube. I tell everyone that when the engine does die i’ll just put another one and start over . Just wanted to thank you…

Gold and platinum mines applied AFMT in the mines’ underground air-conditioning systems and realized significant results. Prolong Transmission, Gear & Differential Treatment was used in cooling tower gearboxes in which temperature reduction helped in the elimination of heat overload or cut out switch. Also, the use of AFMT in bearings surrounding shaft winders has doubled the life of the bearings. Gold Fields Group and other gold and platinum mines, South Africa

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 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. Tim B., Dillwyn, VA

Production drive-line gearboxes used at an assembly plant have historically been replaced at 2-4 gearboxes per month. The gearboxes tended to operate at fairly high temperatures. Upon the application of Prolong AFMT the gearboxes remained only warm to the touch. All 400+ gearboxes on the production line were treated with AFMT. It was been over 41/2 years and the plant has had NO gearbox failures in Prolong-treated equipment. Manufacturer of automotive parts
