BG Fuel System Cleaner 2-Pack — 2 x 11 oz Cans, Concentrated Injector Cleaner & Power Restorer

BG 44K is a concentrated gasoline fuel-system cleaner and power restorer delivered in two 11 oz cans to quickly remove deposits from injectors, intake valves and combustion chambers.

Designed for routine maintenance or targeted restoration, BG 44K is added to gasoline to dissolve and flush carbon and varnish that build up inside the fuel system. It works on fuel injectors, ports, intake valves and combustion chambers, helping to recover lost responsiveness and smooth engine operation without requiring mechanical disassembly. The formula is compatible with common fuel types including alcohol blends, safe for catalytic converters and oxygen sensors, and is trusted by automotive professionals for decades.

How does BG 44K improve engine performance?

BG 44K breaks down upper-engine deposits that restrict fuel flow and disrupt spray patterns, which can cause hesitation, stumble or power loss. By cleaning injectors and combustion areas, the engine can burn fuel more evenly and regain throttle response.

• Restores injector spray pattern for consistent atomization
• Removes carbon from intake valves and ports
• Helps recover lost horsepower and smoother acceleration
• Reduces surge and stumble caused by deposit‑related irregularities

How do I use these 11 oz cans in my vehicle?

Each 11 oz can treats up to 20 gallons of gasoline, so add the recommended can to a mostly full tank and then fill with fuel to mix. For heavy deposits or older engines you can use multiple cans over successive fill-ups to accelerate cleaning.

• Add one can per 15–20 gallons of gasoline
• Pour directly into the fuel tank before filling to ensure dispersion
• Use during normal driving; no special equipment needed
• Repeat as needed for badly fouled systems or as part of regular maintenance

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

BG 44K is formulated for gasoline engines and works with modern fuel-system materials as well as alcohol-blended fuels. It contains no alcohol and is safe for catalytic converters and oxygen sensors when used as directed.

• For gasoline engines only—do not use in diesel engines
• Compatible with ethanol-blended fuels and typical fuel additives
• Safe for fuel pumps, lines and seals when used per instructions
• Trusted by technicians for over 40 years in a wide range of vehicles

Who this is for: BG 44K 2-pack is ideal for owners who want a professional-grade fuel-system cleaner on hand for routine maintenance, drivers experiencing hesitation or rough idling, and mechanics seeking a reliable product for restoring injectors and intake components. It’s useful for single-vehicle households who want occasional treatment or for shops that prefer stock-ready cans. Note: this product can expose you to chemicals known to the State of California to cause cancer and reproductive harm—handle according to label warnings and local regulations.
