BG Fuel System Cleaner 4 Pack — 44K concentrated gasoline additive, treats 20 gal per can, restores power and fuel efficiency

BG 44K Fuel System Cleaner Power Enhancer is a concentrated gasoline additive that rapidly removes deposits from injectors, intake valves and combustion chambers to restore engine responsiveness and fuel efficiency.

BG 44K is a professional-grade fuel system cleaner sold in a four-can pack for repeated treatments. Designed for modern gasoline engines including direct injection systems, each can treats up to 20 gallons (75 liters) of fuel and is formulated to dissolve coked deposits, varnish and corrosive build-up without harming fuel system components, oxygen sensors or catalytic converters.

How does BG 44K improve engine performance?

By breaking down deposit layers that form on injectors, intake ports and combustion chambers, BG 44K helps restore the original spray pattern and airflow. That leads to smoother throttle response, fewer stumbles and regained power without mechanical disassembly.

• Reconditions fuel injectors and cleans intake valves for better atomization
• Clears combustion-chamber deposits that cause knock and power loss
• Reduces hesitation, surge and rough idling related to deposit build-up

When should I use this cleaner and how often?

Use BG 44K as a targeted treatment when you notice drivability issues or as preventive maintenance every few tankfuls depending on driving conditions. Each can treats up to 20 gallons (75 liters), making it practical for periodic care or for restoring performance after long-term fuel deposit accumulation.

• Add one can per 20 gallons of gasoline (75 liters) for a single treatment
• Use more frequently for engines with heavy deposit history or direct injection systems
• Safe with alcohol-blended fuels and common aftermarket fuel additives

Is BG 44K compatible with my vehicle and fuel system parts?

BG 44K is formulated to be safe with typical fuel system materials and modern engine components. It contains no alcohol and is labeled safe for catalytic converters and oxygen sensors, making it suitable for most gasoline-powered vehicles.

• Works with port and direct-injection gasoline engines
• Compatible with rubber, plastic and metal fuel system parts
• Non-corrosive treatment for fuel sending units and injector tips

How quickly will I notice results after using BG 44K?

Some improvement can appear on the first tank after treatment, especially with moderate deposits; more severe build-up may require repeated applications. Expect better throttle response, fewer hesitations and potential fuel economy gains as deposits dissolve and combustion quality improves.

• Initial drivability improvements often visible after one treatment
• Full restoration depends on deposit severity and number of applications
• Works faster on light-to-moderate deposit accumulations
