A. BG 245 Premium Diesel Fuel System Cleaner dissolves deposits across the diesel injection system, including internal injector deposits (IDIDs) in HPCR engines. The 325ml bottle (245E) is the standard single-treatment size for typical passenger-car tanks.
A. The 325ml (245E) is the standard single-treatment size for typical passenger-car tanks. For workshop, fleet or multiple vehicles, the 946ml (24532) is the bulk option.
A. Add to the diesel fuel tank. One 325ml bottle treats a typical passenger-car fill. For larger tanks or workshop use, the 946ml bottle (24532) is appropriate. Drive normally — one tank per treatment.
A. BG 245 incorporates improved chemistry specifically for heavier deposits in modern higher-pressure HPCR diesels, including more effective removal of internal diesel injector deposits (IDIDs). BG 244 is the standard product; 245 is the premium variant.
A. BG 245 contains a cetane improver that supports cold starting on diesel engines. If poor cold starting is due to fuel-system deposits or low cetane, BG 245 can help. Mechanical glow-plug or compression issues are not addressed.
A. Yes. BG 245 is safe for diesel particulate filters, oxygen sensors and catalytic converters. Complies with low-sulphur diesel requirements. Contains no alcohol.
A. Yes. BG 245 is compatible with standard UK pump diesel including B7 (7% biodiesel blend) and mixes with all diesel fuels.
A. Yes. BG 245 contains a fuel lubricity agent that protects fuel-system components — particularly relevant given the lower lubricity of modern low-sulphur diesel fuel.
A. Yes. BG 245 is added to the diesel fuel tank and does not contact the AdBlue circuit, which is a physically separate system. Safe for use on SCR-equipped diesels.
A. BG positions BG 245 as a periodic restorative fuel-system treatment, used at major service intervals or when symptoms of deposit-related performance loss appear. For lighter maintenance, BG 244 or BG DFC is more appropriate.
