Pros:Improves fuel injector performance in certain situations

Cons:Expensive
Will not cure badly clogged or worn fuel injectors

The Bottom Line: Recommended as an additive for diesel fuel systems in need of minor injector maintenance


Those of us that drive cars and trucks with diesel engines are well aware of the advantages of such powerplants when properly maintained.  Diesel engines can last for hundreds of thousands of miles before requiring rebuilding or replacement.  They have no spark plugs or ignition equipment to service, and are very fuel-efficient.  Yet like any mechanical device they require some maintenance.  The two most important systems on a diesel engine are the battery/charging system and the fuel delivery system.  The latter uses expensive fuel injectors, which must be kept clean for optimum performance.  This is hard to do with the variying quality of diesel fuel sold these days, whether made from biological sources (bio-diesel) or petrochemical ones.  The use of poor-quality or poorly-stored diesel fuel combined with a lack of maintenance can cause premature wear, fuel system corrosion, injector spray pattern changes and/or blockage, and reduced fuel economy.  Lubro-Moly developed Diesel Purge to address these issues. 
 
Product Features
According to the manufacturer, Diesel Purge contains Naptha, 2-Ethylhexyl Nitrate (cetane booster), a small amount bit of Benzene, and a proprietary blend of fuel detergents.  Naptha aka “white gas” is a flammable light volatile hydrocarbon solvent that is high in cetane, which is a quality rating for diesel fuel.  (Up to a certain point higher cetane fuels have shorter ignition delay periods than lower cetane fuels, and provide increased efficiency from a given quantity of fuel).  Benzene is a flammable light volatile solvent and known carcinogen (avoid breathing fumes).  Like naptha, it is primarily added to increase the cetane rating of diesel fuel. 

Added to a low-quality diesel pump fuel, the cetane boosters improve the efficiency of the fuel and may make the engine run more smoothly.  However, it is actually the proprietary detergent ingredients that do the important work of cleaning and loosening fuel residue deposits.  
   
When added to diesel fuel, Diesel Purge is advertised to clean the fuel system, break down deposits in fuel injectors, improve the ignition performance of diesel fuel.  It is also claimed to act as a fuel stabilizer, while providing protection against corrosion.  Diesel Purge contains no alcohol to attract water or dry out rubber fuel lines, and is made in Germany.  

Product Hazards
Diesel Purge is a combustible liquid and must be kept away from fire or excessive heat. In a fire, a pressure increase will occur and the container may burst.  The product is harmful or fatal if swallowed, and vapors should not be inhaled.  Contact with eyes or skin should be avoided.  Skin and/or eye contact should be treated by immediately flushing with clean water for fifteen minutes, followed by professional medical attention.
 
Product Usage
As a fuel additive, Diesel Purge can be poured into the fuel tank to blend with the diesel.  Used in this manner, it acts as preventative cleaning agent to keep injectors and fuel lines clean.  The recommended service interval for treating diesel fuel (adding to the tank) is once every six months.

In cases where fuel injectors are already showing signs of reduced performance (hesitation, reduced fuel economy, increased emissions), a different procedure is required.  This consists of using Diesel Purge full-strength by disconnecting the conventional fuel delivery from the tank.  This can be accomplished in some vehicles by detaching the flexible fuel line(s) running from the tank at the fuel filter or other convenient junction, placing the line(s) into a full can of Diesel Purge, then running the engine at varying speeds until the can is empty. 

Alternatively, Diesel Purge can be introduced by means of a professional fuel injector service kit made to fit a specified model of diesel car or truck.  After installation, the engine is idled, then run at varying speeds until the product has been completely consumed.  

I most recently used Diesel Purge on a 2003 Volkswagen TDI with a 1.9 liter diesel engine.  While the engine showed no obvious signs of fuel injector problems, mileage had declined to 36 mpg in combined highway/city commuting, even after replacing all fuel and air filters.  I first obtained a simple adapter kit with two adapters made to fit my Volkswagen’s fuel lines.   After disconnecting the twin flexible fuel lines to the injection pump at the fuel filter, I attached two plastic adapters to both lines.  I then attached a short length of clear fuel line to both adapters.  Placing the ends of both clear lines into the can of Diesel Purge, I started the engine and let it idle for a couple of minutes, then ran the engine at various speeds for the next five minutes or so until the can was completely empty.  I then removed the clear fuel lines and replaced the fuel filter, which I prefilled with more Diesel Purge, then reinstalled the factory lines to the fuel filter.  After driving around a bit, I drove to the filling station, and filled the tank with diesel.  After a period of driving the same commute, a check of fuel economy showed an increase of 3 mpg to 39 mpg.

Diesel Purge has also been useful when used twice a year in the fuel tanks of my 1-ton Ford pickup with an older Navistar (IH) diesel engine.  This truck still uses its original injectors, while delivering up to 22 mpg in highway driving.

Like most fuel injector cleaners, Diesel Purge is not a miracle cure, and may not adequately clean a set of injectors that have seen years of use without proper cleaning and maintenance.  In such cases, fuel injector removal for cleaning and/or replacement will be required in order to restore injector spray pattern and performance.

Conclusion
In my experience, when used as directed, Diesel Purge is effective at reducing or cleaning out minor fuel residue deposits and extending the interval between fuel injector removal/replacement.
