B-12 0116 Chemtool Fuel Injector Cleaner, 15 Ounce

Berryman B-12 Chemtool® – Carburetor, Fuel System & Injector Cleaner

Restore peak engine performance with Berryman B-12 Chemtool®, a powerful cleaner formulated with 100% High-Energy Solvent Technology (H.E.S.T.). This advanced formula quickly dissolves gum, varnish, and fuel residues throughout the entire fuel system—including the fuel tank, lines, injectors, intake valves, rings, and pistons. It also effectively disperses moisture in conventional gasoline, helping to prevent corrosion and buildup.

Key Benefits:

• Cleans carburetors, fuel injectors, intake ports, and valves

• Improves fuel system efficiency and engine compression

• Reduces repair frequency and operating costs

• Increases spark plug and injector lifespan

• Safe for use with catalytic converters and oxygen sensors

• Available in consumer and commercial sizes

Directions for Use:

• Add the full contents of the can to your gas tank to treat up to 21 gallons of gasoline.

• For marine engines or smaller fuel tanks (under 15 gallons), use 1 oz per gallon of fuel.

• For best results, add before refueling to ensure proper mixing.

• For regular maintenance, use B-12 Chemtool Fuel Injector Cleaner every third tank.

Note: High-mileage vehicles or those with infrequent maintenance (beyond every 3,000 miles) may require a deeper clean. For complete restoration of older or neglected fuel systems, use Berryman B-60 High Mileage Fuel System Rejuvenator (Part #7516), featuring a proprietary blend of high-performance detergents and powerful solvents.

Maintain cleaner engines, smoother performance, and longer-lasting components with Berryman’s trusted fuel system solutions.
