A product whose time has come!

What is RxP? RxP is a blend of liquid hydrocarbons. Hydrocarbons are a natural occurrence in gasoline and diesel fuel. The blending process of RxP Fuel Treatment is a proprietary trade secret of RxP Products, Inc. and is not available for publication.

What does RxP do? RxP has many benefits. RxP significantly reduces harmful polluting emissions, increases fuel economy (mpg) in most engines, decarbons engines, cleans fuel injectors and catalytic converters, adds horsepower, reduces engine pinging, reduces or eliminates Black Smoke. These benefits result from de-carbonization of the combustion chamber. RxP ultimately gives the user smoother and quieter performance.

Will RxP increase my fuel economy (mpg)? Yes. Usually, depending on the engine. Based on tests by independent laboratories (not on our payroll) an average engine will run more efficiently due to decarbonization, increased fuel burn and cleaned fuel injectors, all of which result in greater fuel economy (mpg).

How do I use RxP for best results? If RxP is not included in your fuel at the pump, you should add your RxP according to label instructions when you refuel. For initial use see page 13, ‘How to use RxP’ for individual bottle users’.

What will happen if I add more than recommended? Will RxP work better? No. RxP begins working within 15-minutes of engine operation. Use as recommended for best results. Don’t waste your money; over-treatment will not harm your engine. However, it also will not result in additional benefits.

Does RxP increase octane or cetane? Yes. Most U.S. fuels and fuels in many other countries contain at least two percent (2%) oxygenates. The refined oxygenates in fuel combined with RxP tend to increase both octane and cetane by as much as one percent (1%). That might not seem like much of an advantage, but it is in terms of petroleum refinery production.

Is there anything in RxP that could damage an engine? No. In over twenty-five years of tests and use; not one engine, exhaust system, or fuel injection system has been adversely affected by RxP.

Does RxP work in fuel containing ethanol, bio-diesel, or gasohol? Yes. When RxP Fuel Treatment is used as recommended, tests show that emissions will be further reduced (from vehicles using fuel blended with those additives as an oxygenate). The percentage of reduction will be equal to that achieved in regular unleaded fuel. Actually, if your vehicle requires high octane (93%), with RxP added you can use regular unleaded fuel (87%) and save money.

How can I tell when RxP is working? After three tanks of fuel using RxP you will notice a significant increase in power starting from zero mph. Curiously, most users know when they are not using RxP more often than when RxP is being used. Truck drivers and boat owners report that they positively know when they have RxP in their fuel.

Does RxP have any affect on engine sensors? Yes. RxP actually (proven by testing analyses) helps keep emission sensors clean (catalytic converters and oxygen sensors).

Does RxP contain lead or other heavy metals? No. RxP Fuel Treatment is blended from non-carcinogenic liquid hydrocarbons found in natural petroleum products. RxP does not contain: solvents, benzene, mineral spirits, alcohol, magnesium, lead, or other heavy metals.

Is RxP legal? Yes. Although RxP is used by some motorists just to pass their State mandated emissions test, it is legal. The manufacturer, along with a host of other environmentally concerned people, recommend the use of RxP to control harmful emissions. Additional benefits such as fuel economy justify regular usage.

Will RxP make the “check engine” notice disappear? No. That message requires the service of a certified technician. However, if you see the code “Emissions/carbon” problem, RxP Fuel Treatment can be used to decarbon the engine, but it may take a technician to delete the message. To save the cost of hiring a technician, try disconnecting a battery cable for at least three (3) minutes. The disconnect time should allow the on-board computer time to reset which could cause the message to disappear.

Why does RxP seem to be so expensive? RxP Fuel Treatment can be purchased in 55-gallon drums at a greatly reduced cost per treatable gallon. However, a 55-gallon drum of RxP will treat 70,400 gallons of fuel.

When RxP is not available through service station pumps, to make RxP available to users who only need to treat 18-20-gallons at a time, it’s necessary and appropriate to package RxP in bottles to accommodate those who need to increase personal fuel economy at that volume of use. Bottles that treat 100-gallons are also available.

The goal of RxP Products, Inc. is to have RxP Fuel Treatment accessible through every gas pump. Sold in such huge quantities to gas stations or refineries, the cost of individual purchases per tank-full would be barely noticeable.

Will I pass State emissions testing using RxP? Yes. With a full tank of fuel, add the recommended amount of RxP and drive your vehicle at least 30-miles. If there are no serious pre-existing mechanical malfunctions and when your engine has been de-carboned it should pass federally mandated emissions tests.
