Three Fuel-System Solutions. One Complete Performance Care Kit.

Give your vehicle a more complete fuel-system maintenance routine with the THREE GUYS Fuel Efficiency Kit, combining three specialized 473ml fuel additives designed for different areas of petrol-engine performance and maintenance.

The kit includes Octane Booster, Fuel Injector Cleaner and Catalytic Converter Cleaner, helping address fuel quality, injector deposits and exhaust-system buildup through three targeted treatments.

What’s Included

1 × THREE GUYS Octane Booster – 473ml
Designed to increase fuel octane by up to +4 points, helping reduce engine knocking and support smoother acceleration and performance when used with suitable petrol engines.

1 × THREE GUYS Fuel Injector Cleaner – 473ml
Helps clean deposits from fuel injectors and fuel-system components to support proper fuel delivery, smoother engine operation and efficient combustion.

1 × THREE GUYS Catalytic Converter Cleaner – 473ml
Designed to help clean deposits within the fuel and exhaust system and support catalytic-converter efficiency and cleaner engine operation.

Key Benefits

Complete 3-in-1 Fuel Care Kit
Three specialized formulas provide a more comprehensive approach than relying on a single fuel additive.

Supports Fuel-System Cleanliness
Helps remove and control deposits that can interfere with proper fuel delivery and combustion.

Helps Maintain Engine Performance
Cleaner fuel-system components can help maintain smooth acceleration and consistent engine operation.

Helps Reduce Engine Knocking
Octane Booster increases fuel octane by up to +4 points to help reduce knocking associated with insufficient fuel octane.

Supports Injector Performance
Fuel Injector Cleaner helps clean deposits that can affect injector spray patterns and fuel delivery.

Supports Catalytic Converter Maintenance
Catalytic Converter Cleaner helps address deposits within the combustion and exhaust pathway as part of preventive vehicle maintenance.

Convenient Three-Bottle Kit
Provides three targeted 473ml treatments in one package.

How to Use

These are three different specialized additives and should be used according to the directions on each individual bottle.

Octane Booster
Add to the fuel tank according to the bottle directions. Your 473ml formula is designed for approximately 40–60 litres of petrol.

Fuel Injector Cleaner
Add to the fuel tank according to the recommended fuel quantity and treatment instructions stated on the bottle.

Catalytic Converter Cleaner
Use according to the bottle directions and recommended fuel quantity.

For best results, add fuel treatments at the appropriate stage of refuelling to promote proper mixing with the fuel.

Important: Do Not Treat the Kit as One Dose

The three bottles serve different purposes. Do not automatically pour all three bottles into the fuel tank together unless your product instructions specifically state that they can be combined.

Always follow the individual dosage and usage instructions printed on each product.
