BG Diesel Fuel System Cleaner 245 Premium — Restores Injectors, Reduces Emissions & Aids Cold Starts

BG 245 Premium Diesel Fuel System Cleaner is a concentrated formula that dissolves deposits throughout the entire diesel injection system, including inside injectors and combustion chambers.

Diesel engines are prone to fuel breakdown and deposit formation, especially in modern high-pressure common rail (HPCR) systems where heat and pressure accelerate carbon buildup. BG 245 targets both external and internal injector deposits, restoring spray patterns, reducing emissions, aiding cold starts and improving overall drivability. It also contains additives to improve fuel lubricity and boost cetane for smoother ignition in low temperatures.

How does BG 245 remove deposits inside injectors?

BG 245 uses strong solvency and deposit-dispersing chemistry formulated to penetrate hard carbon and varnish layers found both on injector tips and inside injector bores. Its action is designed to dissolve residue that typical cleaners can’t reach, helping restore proper fuel atomization and combustion.

• Penetrates injector internals to dissolve carbon and varnish
• Restores injector spray pattern and corrects fuel flow
• Safe for modern HPCR systems with targeted dosing

What improvements can I expect after treatment?

Treated engines commonly experience smoother idle, reduced smoke and improved throttle response as injectors return to their intended performance. Cold starting can be noticeably easier thanks to the cetane improver and lubricity agents included in the formulation.

• Reduced visible exhaust emissions and soot
• Improved cold starts and more consistent idle
• Better fuel combustion efficiency and throttle feel

Is BG 245 suitable for high-pressure common rail (HPCR) diesel engines?

Yes — BG 245 was formulated with HPCR systems in mind, where elevated temperatures and pressures accelerate fuel breakdown and internal deposit formation. The cleaner is effective on the tight tolerances and precision components found in modern diesel injection systems.

• Effective on HPCR and direct-injection diesel platforms
• Helps remove heavy internal injector deposits unique to high-temp systems
• Compatible when used as directed with system materials and seals

How do I use BG 245 safely and effectively?

Follow the manufacturer's dosing instructions and add the product to the fuel tank as part of regular maintenance or when symptoms appear. Avoid skin and eye contact, handle in a well-ventilated area, and store away from heat or open flame; consult SDS for full safety guidance.

• Add specified dose to fuel tank prior to refueling when recommended
• Use periodically for maintenance or to address performance symptoms
• Follow all safety and disposal instructions on the label and SDS

Who is this for: BG 245 is aimed at owners and technicians of diesel cars, trucks and equipment—especially those with modern HPCR direct-injection engines—who want to restore injector performance, improve cold starts and reduce smoke without disassembling the fuel system. It’s suitable for routine maintenance intervals and targeted treatments when deposit-related drivability or emissions issues arise. Note: contains chemicals known to some jurisdictions to pose reproductive risks; follow safety directions on the label.
