Testimonials

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

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…

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

“No questions… Just comments. The way I talk to friends about prolong. You would think I own this company. I have been using these products starting in 1994 with the Engine treatment. Now I use everything you make. I cut grass for a living, and make a good living doing it. At one of my kids birthday party I thought about a good prolong engine treatment demonstration. I got out a yard man push mower,with a 4.5 HP Briggs on it. It uses a splash system for lubrication. Well…the machine holds 1 us qt of SAE 30 of oil. I poured 2 oz of engine treatment in the engine and cranked it up. People watched while I began to mow my yard while a party was …

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 …

I have a 1999 Chevrolet 1500 pickup. This truck has 205,000 miles and has not had a single oil leak or tune-up since I bought it new. Needless to say, I have driven the tires off of this truck several times! Your Prolong Engine Treatment and Transmission Treatment are the reason I am still driving this truck everyday. I put Prolong in the engine and the transmission ever since the manufacturer’s warranty ran out. I will take your product over any warranty any day!!! Thank you, Prolong, for a fine product. Alan V., Plano, TX

“I have been pushing your product on my family and friends since 1996. I was attending DeVry University in 1996 when the unexpected happened to my car. It was a 30 mile trip one way to school. I owned an 84 Z28 and decided to race an older gentleman in his mustang on my way to class on I294. I pushed my stock Z28 way beyond its limits. I won the wimpy race and made it to class with plenty of time to spare. After 8 hours of class I approached my vehicle to see a huge puddle of oil under my car. I checked the dip stick. Dry. I used prolong engine treatment since the day I purchased the car and used the engine boost every oil change. But I never…

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

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

I bought a full size Chevy truck in 1991 with 39,000 miles on it. Today, I have 520,000 miles on it! We have been using Prolong engine and transmission treatment since and have never had any engine problems. Our transmission went out at 100,000 miles. When we had it replaced, we put the transmission treatment in. We were driving down the freeway when the transmission started to free wheel. We found one of the hoses was broke. We replaced it and went on our way. Come to find out the transmission line broke at my house about 120 miles from where we stopped. The transmission has lasted 400,000 miles and my truck is still running as strong as eve…
