Overview

Berryman B-12 Chemtool Carburetor/Fuel Treatment and Injector Cleaner is formulated to address moisture, gum, varnish, and other fuel residues that can build up across modern fuel systems. The result is a cleaner pathway for fuel to flow, with the potential for smoother starts and steadier idling.

Engineered as a multi-system cleaner, it can be used throughout the fuel system, including the fuel tank, lines, injectors, valves, rings, and pistons, with HEST. This broad scope helps keep internal surfaces cleaner and reduces the likelihood of loss of compression or injector sticking over time. While results vary by vehicle and driving conditions, many users report improvements in reliability and reduced repair needs over time.

How it works

  • Disperses moisture and dissolves gum, varnish, and other residues that can impede fuel flow.
  • Targets the entire fuel system, from tank to pistons, supporting cleaner combustion surfaces.
  • Is designed to be catalytic converter and oxygen sensor-safe, reducing worries about downstream sensors.

Practical use cases

  • Before long trips or seasonal storage to help prevent hard starts and hesitation.
  • As routine maintenance to keep lines, injectors, and valves clean during mileage changes.
  • When you notice rough idle, reduced acceleration, or inconsistency in performance, a maintenance treatment may help.

Benefits you may experience

  • Better fuel flow and combustion clarity due to gum and varnish removal.
  • Potential for higher compression and longer injector life by keeping surfaces cleaner.
  • Friendly to modern exhaust sensors and catalytic converters, reducing potential incompatibilities.

Safety and compatibility

The formula is designed to be safe for catalytic converters and oxygen sensors on compatible systems. Always follow vehicle manufacturer guidelines and use as directed.
