Frequently Asked Questions’s Answer’s

Q. Can Centron Fuel Saver Be Used In Underground Storage Tanks?
A. Yes. Laboratory tested to be safe

Q. Can You Overdose Your Fuel With Centron Diesel Fuel Enhancer?
A. No. However, an excessive dose may clean your fuel system so rapidly that a new fuel filter may be required.

Q. Do I Need To Reset ECM?
A. Resetting the ECM will shorten the time required to see improved Mileage and Reduced Emissions. If the ECM is not reset the computer requires a period of time to learn the Improved fuel burn and adjust the amount of fuel supplied to the injection system. The Vehicle’s ECM comes from the factory with a set of default parameters that it uses to operate the engine. After the engine has been driven for a while, the parameters “zero-in” on your normal driving habits and have a tendency to ignore new readings unless they fall outside the factory pre-set default parameters. You can reset the ECU in order to “wake up” the ECM and cause it to re- learn how to operate the vehicle under these Improved conditions.

Q. Does Centron Boost Cetane Ratings?
A. Yes. Centron Diesel Fuel Saver gives the effect of increasing cetane ratings in diesel fuel.

Q. Does Centron Diesel Fuel Enhancer Affect Exhaust Emissions?
A. Yes. Tests on infra-red exhaust analysis equipment indicate a drop in the hydrocarbon and carbon monoxide emissions up to as much as 90 percent. This proves that Centron Diesel Fuel Saver improves combustion dramatically, thus keeping our air cleaner.

Q. Does Centron Diesel Fuel Saver Contain Ny Alcohol, Methanol, Or Isopropyl?
A. No. Centron Diesel Fuel Saver is comprised strictly of etrochemical components that cannot damage your engine.

Q. Does Centron Diesel Fuel Saver Reduce Bacteria Growth In Diesel Fuel?
A. Yes, our product helps to emulsify the water in the diesel and attack most forms of algae commonly found in fuel storage tanks.

Q. ECM, ECU, PCM, OBD1 and OBD2?
A. These acronyms are commonly used within the Automotive Industry: ECM = Electrical Control Module, ECU = Electrical Control Unit, PCM = Primary Control Module, OBD1 = On Board Diagnostic (Early or 1st Version), OBD2 = On Board Diagnostic (Late or 2nd Version).

Q. How Can I Reset The ECM?
A. On most vehicles equipped with ECM it is possible to reset the ECM by disconnecting the battery. Disconnect the negative terminal first then the positive terminal. Leave the cable disconnected for at least 15 minutes. Reconnect the positive cable first, and then reconnect the negative cable. Please check with your owner’s manual prior for any special procedures that you vehicle may require resetting the ECM. You can also have your local repair shop or new car dealership reset the ECM. If you elect not to reset the ECM the Improved Mileage and Reduced Emissions may take up to 2 or 3 tanks of Treated fuel to see improvements.

Q. How Do Centron Diesel Fuel Enhancer Cleaning Agents Work?
A. The cleaning agents in Centron Diesel Fuel Saver removes dirt, rust, corrosion and carbon buildup from vital engine parts.

Q. How Does The Centron Treatment Water Scavenger Work?
A. The water scavenger in Centron Diesel Fuel Saver chemically emulsifies the water with the fuel in your fuel tank and fuel lines, allowing it to be removed through the normal combustion process.

Q. Is Centron Cost Effective?
A. Definitely! When you consider that the product can keep your fuel tank from rusting out, removes moisture from fuel system, eliminates unnecessary injector rebuilding, reduce oil contamination, give better combustion, extend the life of your exhaust system and increase fuel mileage you can’t afford not to use Centron Diesel Fuel Saver.

Q. Is Centron Covered By Product Liability Insurance?
A. Yes.

Q. Is Centron Diesel Fuel Enhancer Flammable?
A. No Centron is combustible however safe to ship and to carry in your vehicle.

Q. My Miles Per Gallon (MPG) only showed a slight improvement!
A. All vehicles need to cycle through 3-4 full tanks of fuel treated with Centon Fuel Additive to see improvements. Also note any abnormal driving conditions as stated above. Allow time for the ECM to recalibrate to the Improved Fuel Burn.

Q. What % Fuel Savings Can You Expect From Centron Fuel Enhancer?
A. There are so many variables affecting fuel mileage, it’s almost impossible to determine the exact percentage. 3rd party & Company test results indicate that a 5%-15% fuel

Q. What Effects Does Centron Diesel Fuel Enhancer Have On Over-run (dieseling)?
A. Centron Diesel Fuel Saver helps to reduce over-run-on (or dieseling) by improving the fuel burn. It actually changes the burn ratio of the fuel.

Q. What Happens To My Manufacturers Warranty After The Use Of Centon Fuel Additive?
A. A manufacturers (OEM) requirements for the use of any fuel product is that the fuel product must comply with the relevant country fuels specification. Centron Diesel Fuel Additive is SABS tested and re-certified by SABS each year, approved and certified to SANS 342 and EPA registered. Centron is fully compliant with the fuel requirement laws and cannot void OEM engine warranties. In addition, a vehicle manufacturer cannot legally void the warranty on a vehicle due to an aftermarket part or fuel additive unless they can prove that the aftermarket part or fuel additive caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C))

Q. What If My Check Engine Light Comes On?
A. If prior to the Centon Fuel Additive treatment no trouble codes were found and the check engine light intermittently appears in most cases there is nothing to worry about. If prior to using Centon Fuel Additive trouble codes were found but ignored and wiped out by the ECM reset then the ECM has found the original problem again. Repair maybe required. Documented cases has shown that Centron Fuel Additive will clear codes related to emission sensors needing to be replaced, i.e. Oxygen sensors, EGR, etc… Most sensors fail from Carbon deposits and scale. Most emission sensors will last longer do to the Reduced emission and reduction of Carbon. With regular use Centron Fuel Additive scale and Carbon deposits on these sensors will be clean and extend the usable life.

Q. What If My Fuel Economy Goes Down?
A. A reduction in fuel economy during the first 2 or 3 tanks after adding Centon Fuel Additive is a positive sign that the Centon Fuel Additive is cleaning up the engine. Centon Fuel Additive not only allows for a more complete fuel burn but also cleans and removes fuel robbing Carbon deposits. An increase in fuel economy will soon follow. If the ECM is not reset the ECM is receiving changed emission data, during these changes the ECM will send default values and run in a “Rich” mode causing the engine to burn more fuel. After using Centon Fuel Additive the ECM will learn these new emission values and start to correct the “Rich” mode to a more economical (‘Lean’) burn.

Q. Why Does My Engine Have A Rough Idle After ECM Reset?
A. Once the ECM has been reset, the ECM must learn how to efficiently operate the engine. During this new learning period (usually a day) the engine may appear to run “rough” this symptom will clear up by itself. Also the idle configuration parameters in the ECM may not have reset itself properly. After resetting the ECM, driving most vehicles will correct itself. Sometimes a rough idle condition will occur as the treated fuel cleans the back of the throttle body. This condition will correct itself within a day or two. If the rough idle continues reset the ECM using the idle reset configuration in the OBD1 or OBD2 (The ECM reset with the OBD1 or OBD2 can be done at your local repair shop or at new car dealership).

Q. Why Is It Important To Know The Miles Per Gallon (MPG)Before The Install?
A. It provides a baseline or reference through which we can measure the performance of Centon Fuel Additive. In taking baseline MPG note any abnormal driving conditions Including loads, traffic jams, type of road, idle times, rain, snow, low tire air pressure, dirty air filter, etc. In comparing improved MPG also note any differences as noted above. All of these will affect the MPG.

Q. Why Is It Necessary To Add This Fuel Additive?
A. Centron improves fuel mileage, reduces toxic & exhaust Greenhouse Gas Emissions plus extends equipment life

Q. Will Centron Diesel Fuel Enhancer Cause Fuel Filters To Clog?
A. It may. If your miles per gallon performance begins to drop, we recommend that you change your fuel filter. The cleaning agent in the product eliminates dirt and carbon buildup from your fuel system, which may accumulate in your filter. Your mileage will increase after your first fuel filter change.

Q. Will Centron Diesel Fuel Saver Damage The Finish On My Car Or Truck?
A. No. However, we suggest you remove any product spilled, as it may leave an oily film.
