Testimonials

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

To the Prolong team: On behalf of the entire Jam-Air Motorsports team, we are pleased to report that we opened the season by winning the event at Barona on Saturday night and have taken the early season points lead. In testing on Friday Night… we broke the track records for both ET & MPH. We would like to thank you, Pro Long, & Golden West for all of your support in 2009 so far. Without your support and the efforts of the guys who do all the work on the car, none of it would be possible. The team completed the new body late Wednesday night and we debuted it this weekend at the CIFCA season opener in San Diego, CA. This is the same class th…

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 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…

Hi, I want to tell you how great your SPL 100 is. I have two wrought iron gates on the side of my house separating the backyard pool from the front /street side. On of these gates is hit by our sprinkler system every week and starts to squeak. As it is next to my neighbors Master bedroom window and the fact that I take my dogs out to the front yard every morning about 6 am, I wanted to make sure the gate noise does not wake my neighbor, I would spray the hinge with brand W about once a month. Two years ago I used your SPL 100 and have not had to touch it since. Thank you, John – Corona, CA

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

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 …

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

I’ve been using prolong engine treatment for years and it has helped me to achieve a cleaner interrior engine, and better fuel milage. it may have reduced wear, but i have not proved that with an engine tear down to measure the parts. what i am excited to tell you about, is that with my ’08 4 cyl fusion with the 5 speed automatic, factory tires, and at 90 degrees ferinheight, 43 mpg is expected regularly. you may know that the car when bought new was expected to get 28 mpg with a maximum of 32 mpg (according to the epa mandated sticker.) sometimes the car gets as much as 52 mpg(this higher milage is achieved at 45 mph and often with whatever …

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 AFMT in the crankcase, transmission, front differential, rear differential, and 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 the truck (who was never told of the Prolong addition), noticed…
