Berryman B-12 Chemtool Gasoline Fuel Treatment (15 oz) is a purpose-built fuel system cleaner designed to keep gasoline engines running smoothly by targeting the deposits that slow you down. This 15 oz bottle delivers a proven blend of detergents and protective additives that work while you drive, so maintenance happens between trips rather than during costly repairs.
What makes B-12 Chemtool stand out? It goes beyond basic additives by actively cleaning varnish and carbon buildup on critical fuel-pathway surfaces. The result is crisper throttle response, more consistent idle, and stronger acceleration from the moment you turn the key. Everyday driving, wet or dry, benefits from a cleaner fuel system that delivers fuel more efficiently to the engine.
-
Targeted cleaning power: dissolves gum and varnish deposits on injectors, intake valves, and carburetors, improving fuel delivery and combustion.
-
Protects the fuel system: helps guard metal components from ethanol-related moisture and corrosion, extending the life of pumps and lines.
-
Improved performance: smoother idling, quicker starts, and steadier power delivery across a range of driving conditions.
-
Versatile compatibility: formulated for gasoline engines found in cars, trucks, and many small engines that rely on gasoline fuel.
-
Great for storage and daily use: helps stabilize fuel quality in between fills and reduces the risk of performance dips when returning to a parked engine.
How to use: add the entire 15 oz bottle to a tank of gasoline as part of your regular fueling routine. For best results, use with fresh fuel and drive normally to allow the cleaner to circulate through the system. If you’re dealing with stubborn deposits or preparing for storage, consider a follow-up treatment to maintain cleanliness and performance over time.
Who benefits most: drivers with modern or older gasoline engines who want reliable starts, better throttle response, and cleaner fuel delivery; owners of lawn equipment or small gasoline engines seeking smoother operation; and anyone seeking to protect their fuel system from varnish, gum, and ethanol-related concerns.
With B-12 Chemtool, you’re investing in a practical, engine-friendly solution that maintains fuel-system cleanliness without interrupting your routine. It’s a thoughtful addition to regular maintenance that helps you get more consistent performance from gasoline-powered machines.
