Omstar manufactures 3 types of additives

---

• 1 ounce of Omstar DX1® treats 10 gallons of fuel.
• 1 ounce of Omstar OpenFlame® treats 10 gallons of fuel.
• 1 ounce of Omstar R-4000® treats 31 gallons of fuel.
• Omstar additives are made only of Carbon, Hydrogen, and Oxygen. They contain no metals, alcohols, or other damaging ingredients.
• When burned, Omstar additives are ashless, leaving no residue.
• Omstar additives have an extended shelf-life as they never expire. 
• At minus 40 degrees Celsius, Omstar additives are not damages by heat or cold, and perform perfectly.
• At freezing temperatures, Omstar additives raise the viscosity of the fuel for easier engine starting.
• Easy and safe to handle - Omstar DX1 has a shipping classification 65 "Non-Hazardous"

• "The high molecular weight ester, acting as a synthetic overhead lubricant, partially survives the combustion and contributes an acid moiety to form the chemisorbed iron soap to provide boundary layer lubrication.   Vibration is reduced and engine at idle runs more smoothly and quietly. Smoking is reduced markedly and power, acceleration and fuel efficiency are improved.  Thus, the longer that Omstar D-1280X is used, the greater the improvement in engine performance."
• Cetane improver - improving fuel economy/emissions
• Gum solvent - cleans engine without decreasing engine lubricity
• Carburetor & choke cleaner (gasoline) - cleans engine without decreasing engine lubricity
• Upper cylinder lubricant "Iron soap" lubricant through molecular chemisorption
• Valve lubricant  - lubricates through molecular chemisorption
• Combustion improver - exhaust emissions reduced and fuel economy increased

Scientific Explanation of Effects of Omstar D-1280X® Fuel Conditioner.  

Inventor Morton Fainman, Ph.D., was one of the world's foremost experts on the lubricity powers of synthetic esters. For example, U.S. Patent 4,920,691, issued to him in 1990, cites his 1957 research paper on that subject.   Thus, he had been researching synthetic esters for three decades before what he called his "sudden insight" about combining low and high synthetic esters in one fuel additive came to him in 1988. 

Excerpts from the Patent:

"The additive is a mixture of two straight chain carboxylic acid esters, one having a low molecular weight and the other having a higher molecular weight, and wherein the additive mixture increases the efficiency of the engine and decreases pollution."

"The low molecular weight materials...keep the injectors clean...  The need for a dispersant is eliminated avoiding their sulfur and nitrogen...which form air polluting sulfur oxides and nitrogen oxides upon combustion."

"All materials used in the present invention are composed only of carbon, hydrogen, and oxygen [no metals, sulfur, nitrogen, etc.] thus pollution by the additive itself is minimized."

"The high molecular weight ester, acting as a synthetic overhead lubricant, partially survives the combustion and contributes an acid moiety to form the chemisorbed iron soap to provide boundary layer lubrication.   Vibration is reduced and engine at idle runs more smoothly and quietly. Smoking is reduced markedly and power, acceleration and fuel efficiency are improved.   Thus, the longer that Omstar D-1280X is used, the greater the improvement in engine performance."

US Patent No. 4,920,691 for Omstar DX1 issued in May of 1990 states: 

"...high molecular weight straight-chain carboxylic acid esters survive the combustion in the cylinder and are available to react with the rings and cylinder walls ...this forms a metal soap which provides lubrication in the boundary friction region and is a great improvement over conventional mineral oil-based overhead lubrication. ..." (this process is called "Chemisorption")
