Amsoil Octane Boost Dominator Up to 4 Numbers (354ml)

Octane Power Boost!

The AMSOIL Octane Boost Dominator (354 ml) is a high-performance fuel additive engineered to raise the effective octane rating of gasoline by up to four numbers, improving engine response and performance in two- and four-stroke gasoline engines. Designed mainly for high-performance, off-road or racing use, this octane booster helps reduce engine knock and pinging, improves ignition timing and supports cleaner fuel combustion for enhanced power and smooth operation. 

• Increases Effective Octane Up to 4 Numbers — significantly increases octane rating to help reduce detonation and maximize power output in gasoline engines.
• Improves Engine Performance — helps enhance throttle response, ignition stability and overall engine responsiveness. 
• Reduces Engine Knock & Pinging — lowers the risk of premature combustion noise and stress on pistons under demanding conditions.
• Helps Fuel Burn Cleaner — designed to improve combustion efficiency and reduce carbon buildup in combustion chambers. 
• Versatile for High-Performance Engines — ideal for off-road, racing vehicles, older collector cars needing lead substitute, and any application where higher octane is beneficial. 
• One Bottle Treats ~15 Gallons — a single 354 ml bottle is typically sufficient for about 15 gallons (≈57 L) of gasoline. 

🛠️ How to Use

1. Shake well before use to ensure all components are properly mixed. 
2. Add the entire bottle directly into your fuel tank before refilling with gasoline. 
3. Refill the tank with fresh gasoline to mix the octane booster evenly. 
4. Drive normally — recommended for high-performance use, especially where higher octane is needed to reduce knock/ping. 

The AMSOIL Octane Boost Dominator is a reliable octane enhancement solution for anyone aiming to boost performance, reduce knocking and improve engine response when optimal fuel quality isn’t available.
