How can a single fuel additive improve the performance of both diesel fuel and gasoline? Conventional wisdom says that fuel additives cannot work with both gasoline and diesel fuels. Diesel cetane and gasoline octane are opposite measurements and you usually cannot improve both with the same product.

FUEL MAGIC SAYS: Fuel Magic is not a conventional fuel additive because of the unique way that it works. Fuel Magic's combustion modifier increases the cetane in diesel fuel by about 2 to 2.5 numbers. Fuel Magic's attraction to metal also creates a thin film that penetrates and removes combustion deposits which, in gasoline engines, creates a reduction in the octane demand of the engine. The performance of both diesel and gasoline engines are thus improved using a single product.

How can you predict how many gallons a bottle of gasoline or diesel fuel additive will save? Fuel saving additives often cite improvements based on best case scenarios, sometimes 20% or more...not what an average driver can expect to save.

Here's what Fuel Magic says: Fuel Magic approaches fuel savings by incrementally improving combustion, lubrication and engine cleanliness at the same time. Fuel Magic shows a proven average fuel savings of about 8% using U.S. fuels. This is a proven average, not a maximum potential. Since a 2 oz. squirt bottle treats 80 gallons of gasoline you can expect to save about 8% of that--or 6 gallons.

A 16 oz. pour bottle treats 400 gallons of diesel fuel so a trucker should save 8% of that on average, or 32 gallons of diesel fuel.

Fuel mileage improvement varies widely with the type of fuel, condition of the engine and driving conditions. In parts of the world using less refined fuels the average fuel savings is over 20%.

How can a combustion modifier increase fuel economy? Combustion modifiers increase the speed with which fuel is ignited and burned. How does this increase power and fuel economy?

FUEL MAGIC SAYS: By providing a more complete fuel burn instantaneously at the top of the piston stroke more power is produced and transmitted directly to the pistons which translates to increased fuel economy.

Fuel Magic's combustion modifier and added lubrication will increase power by about 2% to 5% in a brand new clean engine. This becomes even more noticeable in higher mileage engines with combustion deposits. By combining a cleaner fuel burn with combustion deposit removal, power will increase and hydrocarbon exhaust emissions will decrease.

If combustion chamber deposits are a problem wouldn't it be easier and cheaper to use only an internal engine cleaner once a year?

FUEL MAGIC SAYS: By allowing carbon to build up and break away you are increasing the wear on your pistons and cylinders. Fuel Magic will prevent combustion deposits from building up in the first place. And cheaper? On the average, Fuel Magic will save over 5 times its cost in fuel savings alone plus the many other benefits. A clean and lubricated engine will run like new for a very long time.

Is it necessary to add an additional lubricant to fuel? Many people believe that oil from the crankcase is sufficient to keep pistons lubricated and that a fuel additive will not add significant lubrication to the combustion chamber. Won't a lubricant create additional deposits instead?

FUEL MAGIC SAYS: That's old school thinking. Fuel Magic's unique polar compound has a molecular attraction to the metallic surfaces inside the engine which creates a thin film that reduces friction and wear. This attraction helps Fuel Magic penetrate combustion deposits, even hardened ones, and remove them with each firing of the engine. It also prevents injector deposits and corrosion from developing in the fuel system. This thin film reduces friction and wear in both the fuel system and combustion chamber without leaving deposits.

Has Fuel Magic been tested by my engine manufacturer? Will it void my engine warranty?

FUEL MAGIC SAYS: Fuel Magic conforms to the standards set by the World-Wide Fuel Charter; therefore it will not void engine warranties. The Charter was created in 1998 by major engine manufacturers around the world to create fuel and additive standards for their engines. It was last revised in 2006. All fuels and additives within those guidelines are acceptable for use with their engines and will not void warranties. This greatly simplifies the acceptance of new technologies and frees the manufacturers from the obligation to test all of the fuel additives individually. Fuel Magic is safe for all engines.

Fuel Magic is also registered with the U.S. Environmental Protection Agency # 207120001. The EPA has classified Fuel Magic as "substantially similar" to fuel and has determined that Fuel Magic can be used safely with all modern emission control equipment. Fuel Magic is also EPA accepted for bulk treatment of all unleaded gasolines, ethanol fuels, bio-diesel and the new low sulfur diesel fuels.

FUEL MAGIC SAYS TO THE SKEPTICS: Even skeptics like to be proven wrong occasionally. Try Fuel Magic yourself. It provides unique benefits for all gasoline and diesel engines and has a 100% satisfaction money back guarantee.

Q: I used Fuel Magic and my performance improved. If I stop using Fuel Magic will my performance go back down again? - A) Your engine will continue to run better because of the removal of the combustion deposits. However, you won't have the benefit of the combustion modifier and over time, combustion deposits will start to develop again.

Q: How do I measure how much to use? - A) Fuel Magic comes in 16 oz. pour bottles for trucks and 2 oz. squirt bottles for cars, light trucks and other small tanks of fuel. Using the appropriate size bottle makes it easy to add the right amount of Fuel Magic to your tank. It is not necessary to measure exactly. Too much or too little is not a problem. Anywhere within the treatment range is fine.

Q: How can I squirt Fuel Magic past the flap in my fuel tank filler opening? - A) It usually doesn't matter whether the flap is open or closed. Fuel Magic does not evaporate quickly and will find its way into the tank. Just add a gentle squirt of Fuel Magic regularly - either before or after fueling.
