Concentrated Metal-Free Formula:

Maxima Hi-Test uses a concentrated, all-organic formula that's completely free of metal and phosphorus compounds. Unlike older octane boosters that used harmful metals like lead or MMT (manganese), the metal-free formula won't damage oxygen sensors, catalytic converters, or other emissions equipment. The metal-free design also prevents spark plug fouling and combustion chamber deposits. This makes Hi-Test safe for modern engines while still providing effective octane boost.

Increases Octane Number:

Hi-Test increases the octane number of fuel, allowing the engine to run more aggressive ignition timing and higher boost pressure without knock or detonation. Higher octane fuel resists auto-ignition, allowing the air/fuel mixture to be compressed more before the spark plug fires. This increased compression and optimized timing translates directly to increased power output. The octane boost is especially beneficial for turbocharged, supercharged, and high-compression engines.

Eliminates Engine Knock:

Engine knock (detonation) occurs when the air/fuel mixture auto-ignites before the spark plug fires, creating damaging pressure waves. Hi-Test eliminates knock by raising the auto-ignition temperature of the fuel mixture. By preventing knock, Hi-Test protects the engine from damage while allowing you to extract maximum power. The knock elimination is critical for racing applications where engines operate at the edge of detonation.

Improves Combustion Efficiency:

The advanced formulation improves combustion efficiency, allowing the engine to extract more energy from each combustion cycle. Better combustion efficiency means more complete burning of the air/fuel mixture, resulting in increased power output and potentially improved fuel economy. The improved efficiency also reduces harmful emissions and carbon buildup.

Compatible with All Fuels:

Hi-Test readily mixes with all fuel types including pump gasoline, race fuel, nitro methane, and alcohol-based fuels. This versatility makes it suitable for various racing applications, from street cars running pump gas to professional race cars running exotic fuels. The all-organic blend is chemically compatible with all fuel types without separation or precipitation.

Effective at Low Dosage:

The concentrated formula is effective at dosages as low as 1 oz per gallon of fuel. This low dosage requirement means the 16 oz bottle can treat up to 16 gallons of fuel, providing excellent value. Higher dosages can be used for greater octane boost when needed. The concentrated formula also means less liquid volume to carry, important for racing applications where weight matters.
