Klotz Lube Fuel Octane Booster

Why Klotz Lube Stands Out in the Fuel Octane Booster Category

When pump gasoline falls short of what a high-compression, turbocharged, or modified engine demands, a quality octane booster bridges the gap — and few brands bring the engineering pedigree to this category that Klotz Synthetic Lubricants does. With more than six decades of experience formulating synthetic lubricants for racers and performance enthusiasts, Klotz approaches fuel chemistry with the same exacting standards it applies to its oils.

Klotz Higher Octane Booster: What It Does

Klotz's flagship Fuel Octane Booster — available under the product line known as the Higher Octane Booster (KL-626, KL-602, and KL-628) — is a concentrated, top-treat fuel additive engineered to raise the effective octane rating of standard pump gasoline or ethanol-blended fuels. It functions as a tetraethyl lead substitute, formulated to elevate octane levels up to 10 numbers or more depending on dosage and base fuel quality.

The science behind the formula goes well beyond raw octane elevation. By raising octane, the additive stabilizes the flame front inside the combustion chamber and promotes a controlled burn speed — two factors that directly reduce destructive engine knock and pre-ignition detonation. The result is improved throttle response and more consistent power delivery, particularly noticeable in engines that push the limits of pump fuel.

More Than an Octane Enhancer

What makes the Klotz Higher Octane Booster particularly versatile is its multi-function formula. In addition to raising octane, it:

• Cleans fuel system components — including fuel injectors, carburetors, and catalytic converters
• Absorbs moisture in the fuel system to prevent lean-out and corrosion
• Stabilizes gasoline for long-term storage — one ounce per gallon can preserve fuel for six to eight months, while higher concentrations extend that window to sixteen months or more
• Improves lubricity via its synthetic lead-substitute chemistry, helping protect valves, top-ring lands, and injectors

The formula is compatible with both straight gasoline and ethanol-enriched blends, making it suitable for a wide range of modern and vintage powerplants. It is also MTBE-free and safe for use with oxygen sensors and catalytic converters — an important consideration for street-driven vehicles and powersports machines alike.

Engineered for 2-Stroke and 4-Stroke Engines

Unlike some octane boosters aimed narrowly at four-cylinder cars, Klotz's Higher Octane Booster is specifically formulated for both 2-stroke and 4-stroke engines. This makes it a natural choice across a broad spectrum of applications — from high-revving motocross bikes and snowmobiles to go-karts, ATVs, and performance street vehicles. It even addresses the lean-out conditions associated with new oxygenated gasoline formulations, stabilizing those fuels for reliable combustion.

Practical Dosing Flexibility

Klotz offers the Higher Octane Booster in multiple sizes — a 6 oz. bottle (KL-626), a pint (KL-602), and a full gallon (KL-628) — giving users the flexibility to treat a single tank or maintain a bulk supply for a fleet or shop. Dosing is straightforward and scalable, allowing tuners to dial in exactly the octane increase their build requires. As always with concentrated octane chemistry, users should protect painted surfaces during handling.

For riders, racers, and builders who demand precise fuel quality without compromise, Klotz Lube's Higher Octane Booster delivers a technically rigorous solution backed by decades of performance lubricant expertise.
