Race Gas RCG-100016 Premium Race Fuel Concentrate 16 oz Can Up to 105 Octane

Race Gas RCG-100016 is a premium race fuel concentrate formulated to blend with ordinary pump gasoline and transform it into high-octane, high-energy, track-grade racing fuel. Available in a single 16 oz can, this patented unleaded formula can raise pump gas octane up to 105 AKI (R+M/2) — the same octane measurement standard used by professional race fuel manufacturers.

Unlike basic octane boosters that only raise octane by a few points, Race Gas also raises the chemical/BTU energy content of the base fuel to match that of true racing fuel. This is critical because high octane alone without adequate fuel energy can lean out the engine at wide-open throttle, reducing performance.

Key Features:

• Raises pump gas octane up to 100–105 AKI (R+M/2) when blended per the Race Gas blend chart
• Increases both octane AND fuel energy to racing fuel levels
• Just 2 oz raises the octane of 1 gallon of gasoline by 4 full octane numbers
• Patented formula containing fuel hydrocarbons, oxygenates, and organometallic compounds (MMT)
• Laboratory tested using ASTM D 2699 and D 2700 test standards
• Safe for oxygen sensors and catalytic converters — does not contain lead
• Race proven in all gasoline-powered engines including 2-stroke and E85 engines
• Made in the USA
• Single 16 oz can — ideal for first-time users or smaller displacement engines

Octane results are measured as the Anti Knock Index (AKI), the average of the Research Octane Number (RON) and Motor Octane Number (MON), providing an accurate representation of fuel behavior under actual racing conditions at high temperatures and high engine loads. Race Gas is for off-road and competition use.
