BG BG 44K Fuel System Cleaner 12 oz — concentrated non‑alcohol formula restores power & throttle response

BG 44K Fuel System Cleaner is a concentrated fuel additive that quickly removes deposits from fuel injectors, intake valves, ports and combustion chambers to restore engine performance.

BG 44K is formulated to dissolve and carry away upper engine deposits that reduce power, cause hesitation, surging or poor throttle response. Designed to be added directly to a full tank of gasoline, this non‑alcohol formula is compatible with modern fuel system materials and common fuel blends. It is also safe for catalytic converters and oxygen sensors when used as directed.

How does BG 44K improve drivability and engine response?

By breaking up carbon and varnish build‑up across the fuel system, BG 44K restores proper fuel spray patterns and combustion efficiency. That translates to smoother acceleration, reduced stumble, and more consistent idle behavior.

• Removes deposits from injectors, intake valves and combustion chambers
• Helps eliminate hesitation, stalling and engine surge
• Restores throttle response and steadier idle

How do I use it and how much fuel does one can treat?

Pour the entire can into a full tank of gasoline before refueling or immediately after filling. One unit of BG 44K is formulated to treat up to 20 gallons of fuel, making it suitable for most passenger vehicles and light trucks.

• Use one can per 20 gallons of gasoline
• Add to tank before or after filling to ensure mixing
• Can be used as a maintenance dose or for corrective cleaning

Is BG 44K compatible with my vehicle and fuel type?

BG 44K is formulated to work with all common fuel system materials and alcohol‑blended fuels. It’s designed to be safe for catalytic converters and oxygen sensors when used according to instructions.

• Compatible with gasoline and ethanol blends
• Works with standard fuel system components and seals
• No alcohol in the formulation

What improvements to economy and power can I expect?

Cleaning upper‑engine deposits improves combustion quality, which can restore lost power and help recover fuel economy that was degraded by fouled injectors or valves. Results vary by vehicle condition and driving habits.

• Proven to help restore power output and combustion efficiency
• May improve miles per gallon that were lost to deposit build‑up
• Best results after one or more treatments on heavily fouled systems

Who is this for? BG 44K is intended for drivers and technicians who want a fast, concentrated fuel system treatment to address rough running, hesitation, or reduced power caused by upper‑engine deposits. It’s suitable for personal cars, light trucks and fleets using gasoline or common ethanol blends.
