BG 2-Bottle Fuel System Cleaner — 44K Platinum GDI Treatment, Concentrated Cleaner That Restores Power

BG 44K® Platinum is a next-generation gas tank additive that deep-cleans modern gasoline direct injection (GDI) systems to restore performance and improve drivability.

Engineered by BG for today's smaller, turbocharged and direct-injection engines, this two-bottle pack delivers a concentrated treatment designed to dissolve stubborn carbon and varnish that accumulate on injectors, intake ports, valves and combustion chambers. The formula continues to work as it circulates through the fuel system, helping to maintain cleaner components over time while addressing sensor and catalytic converter deposits that harm efficiency and throttle response.

How does BG 44K Platinum clean modern GDI engines?

BG 44K Platinum uses a robust blend of detergents and solvents formulated to attack heavy carbon deposits unique to GDI and boosted engines. It treats both fuel system components and combustion deposits by circulating with the fuel and breaking particles loose for safe removal through combustion or filtration.

• Targets deposits on injectors, intake ports and valves
• Loosens combustion chamber carbon and varnish
• Works continuously as it stays in the fuel system over miles

What performance improvements can I expect after treatment?

After using BG 44K Platinum, drivers typically notice restored throttle response, smoother idling and reduced engine knock or run-on tendencies. Fuel delivery is improved as injectors are cleared and flow is restored, which often translates to recovered power and better drivability.

• Improves combustion efficiency and throttle feel
• Helps restore lost power and smooth engine operation
• Can contribute to recovered fuel economy when deposits were impacting performance

Will BG 44K Platinum protect sensors and the emissions system?

The formulation helps remove deposits from oxygen sensors and cleans catalytic converter-affecting contaminants to support emissions-system function. By reducing buildup that interferes with sensor readings, it helps the engine management system run closer to optimal settings.

• Removes accumulated deposits from oxygen sensors
• Clears contaminants that degrade catalytic converter performance
• Supports more accurate engine control feedback

How do I use these two bottles, and how often should I treat the vehicle?

Each bottle is designed as a concentrated tank treatment; follow label directions for tank size and dosing. One treatment can provide both immediate cleaning and residual protection, and periodic use is recommended to maintain a cleaner fuel system in modern direct-injection engines.

• Pour the recommended dose into a near-full fuel tank prior to driving
• One bottle per treatment typically covers a single service interval as directed
• Repeat treatments on a schedule advised by BG or based on vehicle use

Who this is for: BG 44K® Platinum is aimed at professional technicians, independent shops and vehicle owners with gasoline direct-injection or turbocharged engines who want a high-strength, proven fuel system cleaner. It’s especially useful for late-model cars and trucks where carbon buildup reduces drivability, and for fleets seeking preventive maintenance that helps protect sensors and emissions components. Note: contains chemicals listed by California as reproductive or carcinogenic; handle per label and local regulations.
