“I kept gas mileage records of “before” and “after “adding System “48 PLUS” to my engine- and the results show I’m getting a lot more miles per gallon with it in.
Also, my truck runs smoothers with more power, in spite of having a burnt valve.”

CHARLES BARBOUR
Owensboro, Kentucky

“since putting in System”48 PLUS”- my engine is quieter, has more pep, takes less (gas) pedal to go fast as before, starts better and runs smoother. I gave a friend a can for his pickup truck. Before ha added System”48-PLUS’ to the engine, it was “spark knocking” on the gas he was using. Before driving the 20 to 30 minutes to finish the treatment – the “spark knocking” had stopped. He also noticed the same benefits as I.”

“I’ve used your System 48_PLUS, and found it to be everything you’ve stated. I made a trip to Madera, California, which is 352 miles from San Marcos, over the San Bernardino Mountains. As you said, I was not only amazed at the performance of the car, but also at the increased as gas mileage (Most of the trip was in 100 degree temperatures). The car seems to float (glides) without pressure to the gas pedal.”

“I added System 48-PLUS to my 1979 Dodge St. Regis- and immediately noticed a difference. Faster starts – more power. I’m amazed – Pleased – and can’t believe the extra gas mileage. I think it is the best formula I have ever used – and believe it will go far once it is known.”

W.T. DARNELL
Sulphur, Louisiana

“I have put a can of System 48-PLUS in my 1977 Cadillac and found to my astonishment a vast improvement which I didn’t think could be possible, as my Caddy (so I thought) was running as well as it possibly could. I’m not one to check gas mileage – but I have to admit that there is a noticeable difference.”

“You are selling a good product. No question about it. I have tried System 48-PLUS in my car with 187.000 miles on the engine, and it runs smoother on less gas…just as you said it would.”

M.L.B

“I have tried System 48-PLUS, and know for myself that it works. I put it in my 1971 Chevy Van which was running real sad. After 200 miles or so, there was a big improvement in the Van’s performance and gas mileage.”

“Have you got a product! I bought a can for my car – and cannot believe the results. I’m sold on System 48-PLUS!”

Mrs. J.A.
Smyrna, South Carolina

 “Since adding System “48-PLUS”- my 1974 Buick Riviera glides on the roads of my travel. I’m not only getting increased gas mileage- but also all the remaining benefits labeled on the 8 oz. can of System “48-PLUS”.
I personally have, and am experiencing, that System “48- PLUS” actually does as so specified on the container. I find it to be the greatest discovery in an engine friction suppressor in our era of time.
In past years, I have tried other formulas- and the results were nil. It is incredible how System “48-PLUS” actually works!”

John A. Wynn, Jr.
Edenton, North Carolina

“I am a diesel Mechanic. I have tried System 48-PLUS in my Pick-up and in my wife’s car. It seems to be a wonderful product.
It upped our gas mileage.”

Luis R. Cruz

“Within 100 miles after treating the engine of my 1969 Chevy Pickup, I noticed an improvement of plenty of power and a quieter engine. Great results!
I think and believe System 48-PLUS to be one of the finest products I have ever used on an engine.”

Frank S Faria
Somerset, Massachusetts

“I added System 48-PLUS to two cars- and both of them run better with quieter engines, more pickup and better gas mileage.
One car had valve lifter noise- but since application is now very quiet and runs real smooth.”

Paul M. Fitzgerald
Lincoln, Nebraska

“I added System 48-PLUS in my 1977 Ford Granada- and noticed my first benefits within 100 miles… with more gradual improvements for 2,000 miles.
I got better gas mileage and much smoother and quieter-running motor.
I’ve had a valve noice (some asked me if I had a Diesel). Even that is 60 to 80% quieter. This I did not expect.
Folks say they are surprised at the increase in power and decrease in noise.
I heard a distinct bearing noise I never heard before. After 200 miles of driving with System 48-PLUS, it disappeared completely. It seems that I may have stopped trouble before it arrived.”

Archie A Ojala
Seattle, Washington

“Right after application with System 48-PLUS, my 1978 Chevrolet Chevette ran smoother.
After about 100 miles, I noticed it had more power than before.”

“I have used a can of System 48-PLUS in my 1972 Cadillac, and it certainly does the job- better gas mileage- better performance, etc.
The mileage is over 100,000 miles- and it still runs great. System 48-PLUS does everything you said it would.”

G.R.

“My 1981 Olds Delta 88 now runs and idles smoother and quieter. There is a noticeable increase in performance, such as passing and pickup in cold weather.
But the most outstanding benefit of all is the increase in gas mileage- which is almost the same as when the car was new.”

Kenneth E. Oliver
Cheboygan, Michigan

“Your System 48-PLUS is a very good product. I have a 1969 Chevrolet Impala, which I treated as directed.
My acceleration has increased tremendously- my gas mileage has increased- and the most noticeable benefit is the increased acceleration.
I can go uphill on the Long Island Expressway at speeds of 50, and even higher.
It is truly the best formula I’ve ever put in my car.”

It’s fantastic! In no time, my 1977 Fiat with 123,000 miles was purring like a kitten. My friend, who is a former mechanic who worked in the Pits on the Grand Prix Tour in Europe – couldn’t be convinced until I had him drive my Fiat. He couldn’t get over the difference.”

J.F.
Columbus, Ohio

“System 49-PLUS is a superior treatment to any I’ve ever used before. My 1974 Ford Club wagon Van gives better starts, better power, smoother running, less sound of strain on the engine at 55 mph, and better gas mileage. IT WORKS!”

FARRIS NABROS
Cape Girardeau, Missouri

“I gave System 48-PLUS what I call a very good personal test. I have a 1981 A.M.C Concord with 35,289 miles on it. I checked it out and drove to Anchorage and around town. After I got a total of 432 miles – I took a reading of my gas mileage, added System 48-PLUS to the engine, and then made the return trip to Fairbanks. I filled the tank, and found out I had a great improvement in gas mileage. I am now going to try it on one of my big 18 wheel trucks that run to Seattle, Washington – and see how that does.”

A.M
Fairbanks, Alaska

“I added System 48-PLUS to the engine of my 1970 Chevrolet which has 100,000 miles on it.
I keep gas mileage records- and within 100 miles after application, my mileage got better. I also got a smoother running engine, easier starting, more power better compression and a better handling vehicle altogether.
My dad bought a can of System 48-PLUS to put in his 1967 Chevrolet- and he also says he’s getting better gas mileage.
It would be hard for me to try and describe my feelings about System 48-PLUS- because I would need the time it took to write it in a book. In other words, I would call it a miracle!
I think there is no comparison with any other products on the market today. I rate superior- and wish all those poor vehicles out there, had it in their engines!”

Henry Holsapple
Poplar Bluff, Missouri

“I waited until my old jalopy was due for an oil change ( it has 200,000 miles on it)- and then I added System 48- PLUS.
I’ve been a mechanic for 20 years- and still can’t believe it! I suppose you get letters like this all the time- but now-
1. Gas mileage has improved
2. Compression has gone up
3. Runs cooler. Temperature needle does not move going up hills- no matter want the load
4. Engine sounds real solid and cranks up so fast its incredible”

Herndon, Pennsylvania

“My husband and I took a dry run of 104 miles, during which we checked our gas mileage.
We then changed the oil, and added System 48- PLUS. We drove the same 104 miles, same miles per hour- and found our mileage had improved
The car we used was a 1975, 710 Datsun with 40,000 miles. Noticeable was, it took the hills smoother and appeared to have more pep.”

Mrs. M.S.
Phoenix, Arizona

“Within100 miles after adding System 48-PLUS to the engine of my Motor Home- I recorded better gas mileage, besides noticing greater passing speed, better take off and ability to climb hills in 3rd gear.
I thought System 48-PLUS was just another gimmick. I had tried 7 other gas-saving devices- and there was little or no improvement from them.
I notices System 48-PLUS was different, because less pressure on the gas pedal was required. My Motor Home now had incredible passing power- the gas needle went down slowly- I had greater speed taking off from stop lights- and the engine seemed quieter.
System 48-PLUS is a good product that will do as advertised.”

Francis M. Burns
Napa, California

“I’m very well pleased with the performance of my little Honda Accord after I added System 48-PLUS.
It runs smoother than ever, and I’m satisfied, it’s a good product.
The price of it is much better than the Slick-50 that has been talked about."

“First, I treated my 1968 Ford Cortina with System 48-PLUS and noticed that it started easier in cool temperature and ran much smoother.
Then I took an old Briggs and Stratton engine out of my garage that had not been run for 10 years or better. I timed how long it ran on a first tank of gas- and then added System 48-PLUS- and it ran a whole lot longer on the same amount of gas.”

Joseph C Cornick
Wichita, Kansas

“After added System 48-PLUS to my 1984 Honda Civic- I find the engine is running smoother, with more power when climbing hills.”

Ferdinand Domingo
Pittsburg, California

“I just wanted to let you know what your System 48-PLUS has done for my 1973 Chrysler New Yorker.
I had 2 pistons registering low compression. When I added System 48-PLUS to the engine- both pistons rose in compression in only two days of driving.
Plus, my wife’s Chrysler Le Baron would start and stop several times in the morning. After adding System 48-PLUS, the next morning the engine started and held
Our thanks for saving us so much money on repairs.”

R.A.

“Since adding System 48-PLUS to my Chevy Camaro, my gas mileage has been greatly increased- and there is less smoke or engine noises.
I also find the engine to be more smooth, more powerful and maneuverable.
I feel that every car owner should apply System 48-PLUS to save on engine repairs and tears. I, for one, was so satisfied with the product, because I can feel the change in the engine.”

John P. Ignacio
Agana, Guam

“The reason I bought your System 48-PLUS was because I have a 1976 Ford Pick-Up with 121,000 miles on it- which had a valve “tick”.
I previously tried another well known formula- but it didn’t stop the “tick”. So I tried 1 can of System 48-PLUS. It stopped this valve “tick”.
I am very pleased with your product.”
