SMA ProQor Berryman B-12 Chemtool Fuel Injector Cleaner 3-Pack (3×15oz) concentrated additive with shop towel

SMA ProQor Berryman B-12 Chemtool 0116 (3-pack) is a professional-strength gasoline fuel system cleaner that dissolves gum, varnish and carbon to help restore injector spray patterns, carburetor function and smoother engine operation.

Keep your gasoline engine running cleaner without removing parts: this bundle includes three 15 oz bottles of Berryman B-12 Chemtool 0116 concentrated fuel system cleaner plus one reusable SMA ProQor shop towel. The liquid is formulated to flow through fuel tanks, lines, carburetors and injectors while the engine runs, targeting deposits that restrict fuel flow and hinder atomization. Use it as a routine preventive treatment or as part of a targeted tune-up to address rough idle, hesitation or poor throttle response.

How does this product clean my fuel system while the engine is running?

Berryman B-12 Chemtool is a pour-in fuel additive designed to circulate with gasoline. As the treated fuel travels through the system, solvent components soften and dissolve gum, varnish and carbon, which are then burned off in the combustion chamber or flushed through the fuel system.

• Concentrated formula mixes with tank fuel for full-system coverage
• Targets injectors, carburetors, intake valves and combustion chambers
• Works without disassembly—treatment during normal operation
• Safe for catalytic converters and oxygen sensors when used as directed

What performance improvements can I expect after using it?

Consistent use helps restore proper fuel flow and spray atomization, which often translates to smoother idle, crisper throttle response and more efficient combustion. Improvements depend on the severity of deposits and vehicle condition, so some effects may be gradual.

• Reduced hesitation and improved throttle feel on acceleration
• Potentially steadier idle and fewer stumbles at low RPM
• Cleaner injectors and ports can extend spark plug and injector life
• May help lower maintenance need by removing built-up residues

How do I use the Berryman B-12 Chemtool safely and effectively?

Pour the recommended amount of cleaner into a near-empty fuel tank, then refill with gasoline to mix. Run the engine through normal driving conditions so the additive can travel through every fuel system component; follow label instructions for dosage and safety precautions.

• Use one 15 oz bottle per treatment per label directions
• Add to fuel tank and drive to circulate the cleaner through the system
• Store upright, away from heat and open flame
• Wear gloves and use the included SMA ProQor towel for spills or cleanup

What exactly comes in this bundle and why include a shop towel?

This kit supplies three 15 oz bottles of Berryman B-12 Chemtool 0116 and one durable SMA ProQor shop towel. The towel is a convenient accessory for wiping up drips, cleaning parts during inspection, or keeping your workspace tidy while treating the fuel system.

• Three 15 oz bottles for multiple treatments or servicing several vehicles
• Reusable SMA ProQor shop towel for spill control and parts cleaning
• Professional-strength formula suited for routine maintenance and deeper cleanings
• Package supports preventive care and targeted restoration of fuel system components

Who is this for: this bundle is aimed at car owners, DIY mechanics and professional technicians who want a concentrated, easy-to-use fuel system cleaner for gasoline engines. It’s suitable for those maintaining late-model cars as well as older vehicles with deposit-related performance issues, anyone seeking an over-the-counter solution to improve fuel atomization and reduce buildup without time-consuming disassembly.
