A. BG 244 is a diesel fuel system cleaner that eliminates internal diesel injector deposits (IDIDs) in HPCR systems. The 325ml bottle (244E) treats 38–60 litres of diesel — typically one or two fills on a passenger car.
A. Add to the diesel tank at fill-up: 100ml per 15–23 litres of diesel, 177ml per 23–38 litres, 325ml per 38–60 litres, or 946ml per 75–150 litres. Drive normally — one tank per treatment.
A. Internal Diesel Injector Deposits (IDIDs) are sticky deposits inside high-pressure common rail (HPCR) injectors that cause sticking, fuel-quantity errors, rough running and emissions failures. Traditional fuel additives cannot reach them — BG 244 specifically targets them.
A. Yes. BG 244 is safe for diesel particulate filters, catalytic converters and oxygen sensors. Complies with low-sulphur diesel content requirements. Contains no alcohol.
A. Yes — HPCR systems are its primary target. BG 244 is formulated specifically for high-pressure common-rail injectors and addresses the deposits that cause sticking, fouling and cold-start problems in modern diesel engines.
A. BG 244 is the standard diesel cleaner for ongoing fuel-system maintenance. BG 245 is the premium variant with improved chemistry for heavier deposits and modern higher-pressure HPCR. Use 244 for maintenance; 245 where deposit load is heavier.
A. BG 244 removes deposit-related performance loss. If an injector has failed mechanically (electrical, nozzle, seat damage) chemical treatment cannot repair it — professional diagnosis is needed.
A. Yes. BG 244 is compatible with all UK pump diesel including B7 (standard 7% biodiesel blend) and mixes with all diesel fuels.
