imageFrequently Asked Questions

Benefits - What does RxP do?
RxP enhances combustion. This provides several benefits including: de-carbonization of the combustion chamber, improved economy in most vehicles, significant reduction in emissions, more horsepower, reduced engine pinging and knocking plus smooth and quiet running.

Bottle- Why is RxP bottled in such a small package?
The manufacturer of RxP is environmentally conscious. Fillers compromise the largest portion of many retail products. RxP is highly concentrated (one ounce treats ten gallons of fuel) and thus less wasteful of our natural resources.

Cetane - Does RxP increase cetane?
Yes, by more than one point.

Check Engine Light - Will RxP make my "check engine" light go off? 
No.  If you get the code "Emissions/Carbon Problem," you can use RxP to decarbonize the engine, however once the light comes on it will probably take a technician to turn it off.  Before you spend the time and effort to schedule this maintenance you can try disconnecting a battery cable for three minutes.  This will reset your computer and will sometimes cause the light to go off.

Cost - Why is RxP so expensive?
Because most people don't want to buy a fifty-five gallon drum, which by the way would treat 70,400 gallons of fuel. All the packaging, shipping and handling charges add up. Eventually we hope to see RxP sold at the pump, where volume use would make the cost basically unnoticeable.

Damage - Is there anything in this product that can damage an internal combustion engine?
No. In over twenty years of tests not one engine, exhaust system, carburetor, or fuel injection system has been adversely affected by RxP. The product is covered by product liability insurance policy.

De-carbonization - What is decarbonization and how does it help the engine?
In the new engine the key word is "carbon," because the carbon that results from this unburned fuel begins to build up inside the combustion chamber (cylinder walls, the top of the piston, head, and exposed parts of the valves). This process is called "agglomeration," which means forming a mass from particles that retains its individuality. The more carbon that builds up over time the less efficient the engine becomes. As the engine becomes less and less efficient it produces more and more unburned fuel, which further speeds up the agglomeration. This robs the engine of performance and fuel economy. In the RxP technology, fuel is formulated to attach all the different molecules within the fuel together during combustion. This causes fuel to burn more completely in the combustion chamber and at the same time it begins a "de-carbonization" process. This de-carbonization is the opposite of the agglomeration process. De-carbonization results in regaining engine performance as well as restoring fuel economy. A clean engine runs better and pollutes much less.

Detectable - Is RxP detectable in gasoline or diesel fuel?
This is an often asked question by race car drives and mechanics. The answer is no. RxP is made from the same ingredients found in gasoline and diesel fuel, which makes it undetectable.

Emission Control Devices - What effect does RxP have on catalytic converters and oxygen sensors?
RxP actually helps keep these devices clean and thus working properly.

Engine (New) - Is RxP good for new engines?
Yes. RxP keeps the engine clean allowing it to operate as designed.

Engine (Old) - Is RxP good for old engines?
Yes. RxP will not harm an old engine.

Ethanol - Does RxP work in fuel containing ethanol?
Yes. Evidence suggest fuel containing ethanol as an oxygenate does burn somewhat cleaner than straight unleaded fuel when measured at the manifold. Tests show the emissions from vehicles using an ethanol blended fuel will be further reduced when RxP is used as recommended. The percentage of reduction will be equal to that achieved in regular unleaded fuel.

Feel - Will I know RxP is in my car?
Yes. After using RxP, most vehicle owners notice when they are not using RxP more often than when they are using the product, they tend to get accustomed to the engine running smooth all the time.

Fuel Savings - Will RxP increase my fuel economy?
Usually, depending on the engine, the average engine will run more efficiently and thus see an increase in fuel economy. 

Guarantee - Is RxP guaranteed?
Yes. RxP carries a 100% guarantee.

Heavy Metals - Does RxP contain lead or other heavy metals?

Horsepower - Does RxP increase horsepower?

Ingredients - What is in this product?
RxP is a blend of liquid hydrocarbons. These hydrocarbons occur naturally in gasoline and diesel fuel. The actual combination and blending process is secret.

Last - How long does it last?
RxP has a residual effect. It lasts for approximately two tanks. After the engine has been decarbonized it will perform better with or without RxP for a period of time (until the engine builds up carbon deposits).

Lawn and Garden Equipment - Can I use RxP in my lawnmower?
Yes, the product is safe for use in all types of small engines as well as two cycle engines. 

Legal - Is RxP legal?
Yes, although RxP is used by some motorists just to pass a mandatory emissions tests, it is legal. The manufacturer, along with a host of other environmentally concerned people, recommend the product be used on an ongoing basis. The additional benefits derived from using RxP justify its ongoing use.

MTBE - Does RxP work in fuel containing MTBE (methyl tert butyl ether)?
Yes, very well.

Octane - Does RxP increase octane?
Yes. Most U.S. fuels, and many in other nations, contain at least two percent oxygenates. These oxygenates along with RxP tend to increase octane by as much as one point.

Over Treatment - If I use more than recommended will it work even better?
No. Use as recommended for best results. Over treatment will not damage the engine, however it will result in no additional benefits.

Reformulated Fuel (RFG) - Does RxP work in reformulated fuel?
Yes. RxP restores the performance sometimes lost as a result of using fuels containing oxygenates.

Time - How long does it take before RxP begins to work?
In most engines within fifteen minutes after adding RxP the HC and CO reading will begin to drop. After extended driving they drop even lower due to a cleaning action of the fuel injectors, combustion chambers, oxygen sensors and the catalytic converter. Read and follow the instructions for best results.

Treatment Ratio - How much RxP do you use per tank?
One ounce (30 ml) of RxP treats ten gallons (38 liters) of fuel. Over treatment is not necessary.

Use - How often do I use RxP?
The product does have a residual effect. One treatment (one ounce to ten gallons of fuel) will last the average vehicle through two tanks of fuel. We recommend you use the product every other tank-full.
