SMA ProQor Berryman B-12 Fuel Injector & Carburetor Cleaner — 4 x 15oz Bottles with SMA Towel, Concentrated

Berryman B-12 Chemtool 0116 is a professional-strength, pour-in fuel system cleaner kit that includes four 15 oz bottles to dissolve gum, varnish, and carbon deposits and an SMA ProQor towel for cleanup.

Keep gasoline engines running cleaner and more efficiently with a ready-to-use bundle designed for routine tune-ups. This kit supplies four 15-ounce treatments of Berryman B-12 Chemtool, a concentrated additive formulated to circulate through the fuel tank, lines, carburetors, injectors and combustion chambers, plus a reusable SMA ProQor shop towel for fast, oil- and solvent-resistant wiping during service. The product tackles deposits that degrade atomization and flow, while the towel helps keep the workspace tidy and parts clean.

How does this cleaner reach clogged fuel injectors and carburetors?

Just pour the recommended dose into the fuel tank; as the engine runs the formula travels with fuel to the injectors, carburetor passages and intake valves. It acts on hardened varnish and carbon to free restricted passages without disassembly.

• Concentrated 15 oz bottles designed for direct tank addition
• Circulates through fuel lines, injectors and carburetor jets
• Dissolves gum, varnish and carbon residues
• Safe for catalytic converters and oxygen sensors when used as directed

What performance benefits can I expect after treatment?

After use, many vehicles show smoother idle and crisper throttle response because fuel atomization and flow improve. Regular treatments help maintain combustion efficiency, which can reduce rough idling and hesitation caused by deposits.

• Improved throttle response and more consistent idle
• Better fuel atomization for cleaner combustion
• May extend life of spark plugs and injectors by reducing deposits
• Supports proper fuel flow to avoid lean or rich running conditions

Is this product easy and safe to use for routine maintenance?

Yes — the additive is a pour-in treatment intended for consumer use; follow label dosing and safety instructions. The formula is engineered to be compatible with modern gasoline systems and emissions equipment when used as directed, and the included SMA towel assists with handling spills or wiping components during inspection.

• Simple pour-in application, no special tools required
• Includes a reusable SMA ProQor shop towel for cleanup and handling
• Clear label instructions for correct dosing and safety precautions
• Designed to circulate and treat the entire gasoline fuel system

How often should I use Berryman B-12 Chemtool?

Frequency depends on vehicle age, driving conditions and fuel quality; many owners use a treatment every oil change or every few thousand miles as preventive maintenance. Heavily contaminated systems or vehicles with long idle periods may benefit from more frequent treatment until deposits are reduced.

• Common preventive interval: with regular service or every few thousand miles
• Use multiple bottles for heavily fouled systems as needed
• Follow vehicle manufacturer recommendations and product label
• Combine with periodic mechanical inspection for best results

Who is this for: This four-pack bundle is aimed at DIY car owners, independent mechanics and fleet managers who want a cost-effective way to maintain gasoline fuel system health without teardown. It’s useful for vehicles showing mild-to-moderate deposit-related symptoms, for routine preventive service, and for anyone who appreciates having an absorbent, durable SMA ProQor towel included for cleaner, safer maintenance work.
