Berryman 0116 B-12 Chemtool Carburetor/Fuel Treatment and Injector Cleaner Review

  • Written by: William Copper

Your vehicle relies heavily on the operational consistency of both its fuel injectors and carburetor when it comes to providing the necessary amounts of fuel directly to your engine for acceleration and performance.

Unfortunately, through the regular use of mixed or unleaded fuel and ethanol over time varnish, carbon deposits, and moisture can build up and block your fuel injectors and carburetor. As these parts are both located within the engine manifold, it’s understandable how they play such critical roles in assuring consistent performance and power. Without regular maintenance, cleaning, and fuel filter changing a vehicle can begin to experience rough idling, startup hesitation, and even decreased fuel economy.

How Berryman Cleans Your Fuel and Carburetors?

Major fuel component and parts cleaners like the Berryman 0116 B-12 Chemtool help to improve a wide range of performance issues often experienced due to a lack of maintenance and cleaning of your fuel injector cleaners and carburetor. A clogged carburetor and fuel injectors can lead to an overall engine hesitation, and even make it impossible to accelerate or maintain RPMs (Revolutions Per Minute) as necessary while driving.

RPM’s represent the necessary rotation per minute of your engine’s operation. This provides and in turn responds with the right amount of power when you push down on your gas, as well as when you’re starting your car (especially “cold-starts”). In fact, cleaning the carburetor can be a very beneficial move in consideration of its major role in mixing and bursting necessary fuel into your engine, with just the right amount of air.

Sometimes it is necessary to completely disable and clean out or replace your carburetor and other major fuel system parts. However, it’s worthwhile for the sake of your budget to first try a reputable carburetor and fuel injector cleaning product like the Berryman 0116 B-12 (12oz), and don’t be afraid to try it out and use it beyond 2-3 times as necessary.
