## Overview

Berryman B-12 Chemtool Total Fuel System Clean-Up is a powerful 15 oz. fuel additive designed to restore engine power, improve fuel economy, and extend injector life by dissolving gum, varnish, and carbon deposits. Safe for catalytic converters and oxygen sensors, it disperses moisture and lubricates upper cylinders, making it ideal for vehicles lacking regular fuel system maintenance. Trusted by users for consistent performance every 5,000 miles.

## Description

Formulated for vehicles that have not had regular fuel system maintenance. Uses H. E. S. T. and powerful detergents to maximize one-tank clean-up of intake valves, fuel injectors, carburetors, and combustion chamber. Dissolves gum, varnish, and carbon deposits in the entire fuel system to help restore lost power and peak performance. Improves starting, drivability, gas mileage, and injector life. Catalytic converter and oxygen sensor-safe.

Review: Use every 5k miles - I use this every 5000 miles or so in each of my cars. Really seems to work well. keeps water out of the tank and lines and seems to keep it all running smoothly.
Review: Bottle states DOES contain polyetheramine (P.E.A.) - Correct item was sent and in perfect condition. This item states has P.E.A. (polyetheramine) yet the information online states it contains an alternative form of P.E.A. and the SDS directly from the manufacturer states it does not contain any P.E.A. Regardless, this stuff works very well and as long as the bottle states it has polyetheramine, I’ll keep using.
