BG 44K Platinum fuel-system additive — 2 bottles concentrated tank treatment that removes GDI carbon and restores injector flow

BG 44K® Platinum™ is a next-generation gasoline fuel-system additive formulated to remove carbon deposits across modern GDI systems, restore injector flow, and improve drivability.

BG’s latest BG 44K Platinum builds on decades of aftermarket fuel-system research to target the stubborn carbon and deposit challenges found in today’s gasoline direct injection (GDI) and boosted engines. Packaged as a concentrated tank additive, this formula is engineered to cling to fuel-system components and provide ongoing cleaning as miles accumulate, helping return lost performance without disassembly.

How does BG 44K Platinum clean gasoline direct injection engines?

The product uses concentrated detergents and deposit-dispersing chemistry designed to dissolve and dislodge carbon on injectors, intake ports, valves, and combustion chambers. It is intended to be added directly into the fuel tank so active ingredients circulate through the fuel delivery and combustion systems.

• Breaks up carbon and varnish that builds on injector tips and in ports
• Restores spray pattern and fuel flow to clogged injectors
• Works in-line during normal driving to carry away loosened deposits

What drivability and engine benefits can I expect after using it?

Users typically see improvements in throttle response, smoother idle, and reductions in engine knock or run-on tendencies as deposit-related issues are addressed. Restored injector flow and cleaner oxygen sensors can also help bring fuel economy closer to factory levels.

• Increases usable engine power and throttle feel
• Reduces rough idling and hesitation caused by clogged components
• Helps maintain catalytic converter and oxygen sensor performance

How often should I use BG 44K Platinum and how is it applied?

BG 44K Platinum is supplied as a concentrate that is poured into the fuel tank; frequency depends on vehicle condition and driving habits. For preventive maintenance, use intervals recommended by BG or your service provider; for heavy deposit removal, a single treatment may be followed by periodic maintenance doses.

• Pour the specified bottle into the fuel tank before refueling
• Follow product directions or technician guidance for spacing between treatments
• Effective for both routine maintenance and corrective cleaning jobs

Does BG 44K Platinum affect emissions or engine components?

The formula is intended to clean oxygen sensors and catalytic converters by removing deposits that impair their function, which can support better emissions performance indirectly. It is not a replacement for required emissions repairs; consult a technician for persistent fault codes or hardware failures.

• Removes deposits from oxygen sensors and catalytic converter surfaces
• Prevents corrosion within the fuel system
• Supports more complete combustion when deposits are removed

Note: This product can expose you to chemicals known to the State of California to cause cancer and reproductive harm. Handle according to label instructions and local regulations.

Who is this for: BG 44K Platinum is suited for professional technicians, independent shops, and vehicle owners who want a concentrated, high-performance tank additive designed to tackle heavy carbon buildup in modern gasoline direct injection and boosted engines. It is ideal for cars and light trucks showing reduced performance or for preventative maintenance on newer vehicles that use GDI technology.
