Hi All!! Well I said That I would give you an update after my letter on 12/20. I purchased another Rxp bottle and have run four tanks of gas through my car. I have changed the oil and air filter and my car is running as rough as any car could. I am goig to emaul the folks at Rxp now and see what they say before I take it into my mechanic. Rick Hunt

Hi All, Looks like RXP has done it again.. The problems that I was having after using rxp, were "NOT" from rxp. They turned out to be a faulty set of plug wires that were purchased six months ago from auto zone.. The car has smoothed out and is running great... Thanks to the staff of RXP for their help in this matter.

Well, must admit I seriously doubted your claims about combustion chamber cleansing.....until we pulled the cracked aluminum head off my neighbors 2.6 liter Mitsubishi pickup truck with > 230K miles on it. I was astounded to see the piston tops and upper cylinder walls looking as if the motor only had 20K miles. And the cylinder heads were virtually clear of any combustion by-product accumulations. Cylinder wall wear is virtually 0. Not knowing how that could be, I simply exclaimed, "How in the world do you manage to keep this area of the motor so clean after so many miles!!" He simply said, "I put RXP in the fuel every two or three tank fulls of gas." Terry's been doing this for the last two years or so since he's owned this used vehicle. Your stuff certainly seems to cost a lot for such a small amount, but what I've seen in that motor we're working on appears to make it well worth the cost!! Karl Holz
I tried the product a few years ago in my diesel mbz and noticed an immediate improvement in performance and fuel economy. Then, i couldn't find rxp anywhere. I just saw some at an auto parts store and tried it in my '74 450SLC MBZ. Wow! Immediate performace boost. I'm going to try a bottle every other tankful for a few thousand miles and get a smog check. I am also going to check the mpg to see if helps. The car only gets about 10mpg if I take it easy. Thanks.
I'd heard about RxP, but basically ignored it. I've got a '91 Acura Legend that I just love...but over the last year it has started to miss, and just did not have the kick it used to have. I've maintained this car at the dealership where it was purchased, and even though it has 134,000 miles on it...well, it's in very good condition.
This car has had all the major maintenance done, plus 92 octane fuel, and fuel injector cleaner treatments on a regular basis. I'm now coming to the conclusion that those other products actually don't work.
I heard Ed Wallace last Saturday, and he said good things about RxP. So I decided that unless I put new injectors in the Legend, plus a value job, I'm not sure she'd ever run right again. I've only had three days of experience, but the miss rate is decreasing, and the performance of the Gold Car is amazing. But I want to see what happens over the rest of this tank of fuel before I start to come to any conclusions.
I plan to run one untreated tank of fuel, and then do another RxP treatment. We'll see how it goes.
But the first impression is very favorable.
Now let me tell you about STP, Gumout, and the rest of the stuff I've pumped through this engine. ^&#*&@#*@&#^*@*&%(@()*&$#!!
Best regards,

Please keep on doing what your doing
I bought RXP about three weeks ago to by the recomendation of a few Autozone workers. I just needed a fuel system cleaner. I drive an 88 Honda civic CRX Si with a few mods. One of the mods is a catco free flowing catalitic converter. 15 minites after I put in the 1.0 Oz of RXP my car sounded like I had no exaust system on it at all. I also noticed a huge loss in power. One month ago the car dynoed at 105 hp at the wheels, after the RXP it dynoed at 90 hp at the wheels-big loss. I went out on the web and posted some questions on some prominent import web sites. What I got back were many people saying not to use RXP, some people said that it rewened there O2 sensor, I checked my codes and my O2 sensor was reading ok but was covered in thick black soot-carbon. I replaced it, no improvement. Some people said that RXP actuly melted there hi flo cat. So I checked my cat and there was the problem!!! The cat was completely melted on the inside, you can't even see through it. It looks like melted plastic in there. So I replaced the cat $122.86 later, and I have my car back, dynoed at 105 hp at the wheels. I am very un happy, I have already taken my old cat to the autozone where I bought the RXP and they could not beleve what it did, but they would not do anything about it.
I would like you to do something, please.
The outcome: Our technician, Duane Fisher, spoke with Dave on July
11th. The problem Dave had with this engine turned out to be caused by one of the
modifications he mentions in his complaint. Without naming names or pointing fingers
lets just say he added a modification which increased his fuel pressure. This in
turn increased horsepower, but also increased fuel flow making the engine run rich - far
too rich. In Dave's complaint he described his damaged catalytic converter by
saying, "It looks like melted plastic in there." This describes how a
catalytic converter looks when burned out due to excessive fuel bypassing the combustion
process. A converter damaged by being overloaded with carbon particles or damaged by
burning leaded gasoline looks quite different. Dave's problem was not caused by
RxP. Now how do we track down all those people out there in the chat rooms that
incorrectly think RxP was the culprit?
Don, I spoke with Mr. Stuntz
on the telephone about his complaint. After
he described the condition of the catalytic converter on his 1988 Honda Civic, it was
obvious that it was caused by an overly rich fuel condition and not RxP. The problem he encountered can be caused by
malfunctioning electronic controls or a leaking or faulty fuel injector under normal
conditions, however in this case it was caused by a modification made by Mr.
Stuntz.
He had installed an after marker fuel pressure regulating system to boost the fuel rail pressure, which in turn increases horse power. The side effect - when pushing the engine hard - is too much unburned hydrocarbons reach the catalytic converter. This will cause the inlet side of the converter to melt down blocking the flow of exhaust gases. I should point out that engines with an electronically controlled fuel system, regardless of manufacture, will experience the same problem if the fuel pressure is raised above the manufacture’s specifications.

I HAVE TO SAY WOW.I USED RXP I MY WORK TRUCK WHICH IS A 1989 F-150 WITH OVER 200,000 MILES.MY SITUATION IS I DRIVE MY TRUCK FROM ST.PETE TO ANYWHERE FROM TAMPA, NEW PORT RICHEY, TO SARASOTA ON ANY GIVIN DAY.NORMALY WHEN I DRIVE TO TAMPA AND GO TO 2 DIFRENT JOB SITES AND DRIVE HOME THROUGH RUSH HOUR TRAFFIC I WOULD BURN BETWEEN A HALF AND THREE QUARTERS OF A TANK OF GAS...NOT TOO GOOD.AFTER USING 1 BOTTLE OF RXP GAS TREATMENT I GO THROUGH ABOUT A QUARTER OF A TANK.I NOW INTEND TO USE RXP IN BOTH MY PERSONAL CAR AND MY WIFES CAR.THANKS RXP!
This stuff really works. Thankyou, for developing a great product.
Have a 1980 Chevy Impala............had to install a used engine, and know not the mileage...but it always passes the auto emmissions test..but lots of blowby. Added rxp, drove 50 miles at 70 mph, and noted that when I parked it, it was very powerful and the smoothest strongest idle it ever had. The oil is like brand new even after 5 months. I have put a lot of junk in bottles from auto parts stores in the car, but this rxp seems really good. Gas mileage is much better too, and sounds smoother running on the freeway.
I was a little skeptical when I saw how small the bottle was, but I tried it and can honestly say that my Nissan truck now runs a little smoother. Pretty good stuff.
Yo RxP,
I drive a 1989 Bronco with a 302 engine with 175,000 miles on the clock. It came time for my annual emissions inspection and I got a jar of your RxP gas kicker, emissions reducer and BINGO passed the test with flying colors with room to spare. While it is a bit pricey, it is the best product available and now I'm able to drive for another year without expensive repairs to an old motor. I drive like the old man that I am and have all racing desires out of my blood except to watch at the track. Maybe that helps keep my old Bronco running well. Thanks for an excellent product that keeps me and my old motor young.
very good
I've writen a comment about 6 months ago, and thought i would follow up on it. I'm still useing RXP in my work truck and my truck is still running stronger than ever. RXP addidtive made a 100% improvement in my truck sence i started useing it. I was a little weary about trying RXP at first, but now I'm glad I tryed it. thanks for a wonderful product.
