Ford Motor Company recommends the use of CGX-4® in their factory-built F600 and F700 series LPG-powered trucks. The Owner Guide reads:

"Use only high quality propane designated as motor fuel (MF). Low quality or non-recommended propane usually contains impurities which can deposit in the fuelock and converter/regulator. Deposit buildup will reduce the vehicle and emissions control performance and increase system maintenance and operating cost. In addition to using only high quality propane designated as motor fuel, the use of a fuel additive such as CGX-4® or equivalent will significantly reduce impurity deposit buildup and is recommended."

A large paper company has been using CGX-4® in their propane engine fuel for more than nine years. Before they used additive, they were continually rebuilding carburetors on their fleet of 90 lift trucks. Now, the problem has been completely eliminated. They also report greatly reduced carbon monoxide (CO) levels in their warehouse.

A Michigan school bus fleet had to clean out vaporizers every two to three weeks because of fuel pollution. The problem was so severe mechanics had to dig deposits out with a screwdriver. Adding CGX-4® cleaned up the systems in a short period of time. The vaporizers have remained clean, with no tear-downs required.

Thirty-nine step vans of an Arkansas laundry delivery fleet had a long-standing history of severe valve problems. After using CGX-4®, they reported a dramatic reduction in maintenance down time in the first year. Valve problems have been virtually eliminated.

Gas Company -United Kingdom has been using CGX-4® since 2001. As of January 2005, they have driven vehicles over the 10 million mile mark. Following the introduction of multi additive CGX-4® to their regular fuel in 2001, they have calculated a minimum of 10 million miles have been covered using CGX-4® in their fuel.  The results have far exceeded expectations, engine life and performance have been greatly extended and improved for 100’s of vehicles whose owners recognised the advantages of using a Premium Grade Fuel.  This is proof that a quality fuel can be more economical than a less costly standard fuel.  CGX-4® prolongs engine valve life, gives better starting (especially when cold), improves consumption, cleans the entire system, and less polluting!

Canwest - Canada had this to say about CGX-4® propane additive since treating all their fuel with CGX-4®:  “We have enjoyed increased sales in the lift truck and ice resurfacing business as a result of using CGX-4®.  As new Workers Compensation Regulations are demanding lower indoor emissions, the CGX-4® product has been a natural. We have been able to show customers the benefit of using our premium fuel as well increasing our margin or at least gain and retain business on a value added basis.  In time when competition is fierce, CGX-4® has given us a definite advantage over our competitors.”

Company in Solvakia had the following test results after treating their vaporizors with CGX-4 Propane Treatment: Test has shown that CGX-4® propane treatment is effective in reducing the build-up of contaminants in vaporizers and noticeable improvements in fuel consumption have been reported (see pictures & results below):

LPG as it passes through carburetors and vaporizers, deposits heavy end buildups.  The hydrocarbon chains break down at this point leaving a buildup of a gummy residue similar to grease. Heavy end buildup in carburetors and vaporizers require constant service, long chain hydrocarbons and other contamination cause combustion problems.  The emulsifiers in CGX-4® slowly soften and remove these buildups to prevent their interference with engine operation.  The oil soluble substance holds insoluble foreign matter in suspension so heavy ends are carried through the vaporizers and carburetors and are burned during the combustion process.  Valves and upper end engine components do not get lubrication from the crankcase and LPG does not naturally provide proper lubrication to these components.  This leads to greater wear and major engine failure.  CGX-4® provides upper cylinder lubrication to the moving parts in the top of the combustion chamber that are not lubricated by the crankcase oil.  This top oil is not completely vaporized in the combustion chamber because of its 425 degree F. (218 degree C.) flash point. This results in a light film coating to the cylinder walls, rings and valves.  The added lubrication increases engine efficiency, reduces operating temperatures and prolongs engine life. Finally, without the use of metallic elements that by themselves can add harmful impurities to the environment, CGX-4® has combustion improving compounds. These compounds minimize pre-ignition in the combustion chamber prior to spark plug ignition of the fuel mixture.  They also provide a more even burn upon ignition, increasing the efficiency of fuel combustion.

Results include: higher pressures in the combustion chamber, increased power, more efficient fuel economy, and a very significant reduction in carbon monoxide, and unburned hydrocarbons in the exhaust gases.
