EPA registered additives are derived from petroleum. EQ Mileage Booster is a reformulator, even though you “add it” to the fuel. Mileage Booster is non-toxic and non-hazardous. EQ Mileage Booster cleans and lubricates the internal parts of the engine without the use of petroleum derived products commonly found in fuel additives. Allowing the engine to burn fuel more efficiently thereby, reducing emissions.

An ester is a group of liquid or solid compounds formed by the reaction of an acid and an alcohol with the elimination of water. There are organic and synthetic esters. For example most natural oils, fats and waxes are esters. More common esters are beer, soap and polyester used in clothing. EQ Mileage Booster contains non-toxic, non-hazardous synthetic esters.
In EQ Mileage Booster a group of low molecular weight esters clean the dirty deposits formed by fuels and the combustion process. These deposits lower performance of an engine making it less fuel-efficient. Causing it to exhaust raw fuel, which is the primary contributor to pollution. A group of high molecular weight esters lubricate the engine surfaces as the fuel runs through it. Their molecular structure is small enough to penetrate the metal and form a lubricating layer between surfaces. This process allows the moving components of an engine to operate smoother and with less power-robbing friction and heat.

In the simplest terms, esters can be defined as the reaction products of acids and alcohols. Thousands of different kinds of esters are commercially produced for a broad range of applications. Within the realm of synthetic lubrication, a relatively small substantial family of esters have been found to be very useful in severe environment applications.
Esters have been used successfully in lubrication for more than 50 years and are the preferred stock in many severe applications where their benefits solve problems or bring value. For example, esters have been used exclusively in jet engine lubricants worldwide for over 40 years due to their unique combination of low temperature flowability with clean high temperature operation. Esters are also the preferred stock in the new synthetic refrigeration lubricants used with CFC replacement refrigerants. Here the combination of branching and polarity make the esters miscible with the HFC refrigerants and improves both low and high temperature performance characteristics. In automotive applications, the first qualified synthetic crankcase motor oils were based entirely on esters and these products were quite successful when properly formulated. Esters have given way to Polyalphaolefins (PAOs) in this application due to PAOs lower cost and their formulating similarities to mineral oil. Nevertheless, way are nearly always used in combination with PAOs in full synthetic motor oils in order to balance the effect on seals, solubilize additives, reduce volatility, and improve energy efficiency through higher lubricity. The percentage of ester used in motor oils can vary anywhere from 5 to 25% depending upon the desired properties and the type of ester employed.

Esters lubricants have already captured certain niches in the industrial market such as reciprocating air compressors and high temperature industrial oven chain lubricants. When one focuses on high temperature extremes and their telltale signs such as smoking, wear, and deposits, the potential applications for the problem solving ester lubricants are virtually endless.

In many ways esters are very similar to the more commonly known and used synthetic hydrocarbons or PAOs. Like PAOs, esters are synthesized form relatively pure and simple starting materials to produce predetermined molecular structures designed specifically for high performance lubrication. Both types of synthetic base stocks are primarily branched hydrocarbons which are thermally and oxidatively stable, have high viscosity indices, and lack the undesirable and unstable impurities found in conventional petroleum based oils. The primary structural difference between esters and PAOs is the presence of multiple ester linkages (COOR) in esters which impart polarity to the molecules. This polarity affects the way esters behave as lubricants in the following ways:

Volatility: The polarity of the ester molecules causes them to be attracted to one another and this intermolecular attraction requires more energy (heat) for the esters to transfer from a liquid to a gaseous state. Therefore, at a given molecular weight or viscosity, the esters will exhibit a lower vapor pressure which translates into a higher flash point and a lower rate of evaporation for the lubricant. Generally speaking, the more ester linkages in a specific ester the higher its flash point and the lower its volatility.

Lubricity: Polarity also causes the ester molecules to be attracted to positively charged metal surfaces. As a result, the molecules tend to line up on the metal surface creating a film which requires additional energy (load) to penetrate. The result is a stronger film which translates into higher lubricity and lower energy consumption on lubricant applications.
Detergency/Dispersency: The polar nature of esters also makes them good solvents and dispersants. This allows the esters to solubilize or disperse oil degradation by-products which might otherwise be deposited as varnish or sludge, and translates into cleaner operation and improved additive solubility in the final lubricant.

Biodegradability: While stable against oxidative and thermal breakdown, the ester linkage provides a vulnerable site for microbes to begin their work of biodegrading the ester molecule. This translates into very high biodegradability rates for ester lubricants and allows more environmentally friendly products to be formulated.

EQ Mileage Booster reformulates any fuel, causing two important benefits. The first benefit is the added lubricity to the engine. The second is adding cleansing properties to the fuel. All of the internal components benefit from the cleansing and lubricating action including the fuel lines, filters, carburetors, spark plugs and injectors. EQ Mileage Booster also conditions the engine seals, keeping them tighter longer. A cleaner, more lubricated engine runs smoother, requires less maintenance and reduces engine heat significantly. Horsepower returns closer to the manufacturer’s specifications. EQ Mileage Booster removes carbon deposits that cause fuel to combust incompletely, resulting in wasted fuel that creates toxic emissions. The combination of cleaning and lubricating esters in EQ Mileage Booster stabilize the fuel without changing its specifications.

EQ Mileage Booster is a product that is added to fuels to make engines burn fuel more completely. EQ Mileage Booster is non-toxic, non-hazardous and works with any fuel used in cars, trucks, buses, ships, trains and generators. EQ Mileage Booster is free of carcinogens and is not derived from petroleum. It utilizes cleaning and lubricating esters suspended in a mineral oil base. EQ Mileage Booster increases fuel economy and reduces emissions. Commercial fleets on average increase fuel mileage between 5% and 20% and reduce emissions by more than 30%. When added to fuel, EQ Mileage Booster reduces the emissions of hydrocarbons (HC), nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM) and other harmful products of combustion.
