A. BG Fuel System Drier prevents moisture-related fuel problems and fuel-line freezing. The 100ml small can (281100E) is the single-tank treatment size for around 15 litres of petrol.
A. 100ml (281100E) is the single-tank treatment for around 15 litres. 345ml (281E) treats multiple fills — about six single-tank applications on typical passenger-car tanks.
A. It absorbs moisture in the fuel system and forms a stable solution with water and petrol, allowing water to pass harmlessly through the fuel system without affecting combustion or causing fuel-line freezing.
A. Add to the petrol fuel tank: 50ml per ~15 litres, 100ml per 19–38 litres, or 177ml per 38–50 litres of fuel. Use when condensation or water contamination is suspected, or as winter preventive.
A. Cold weather (condensation in part-full tanks), prolonged storage, contaminated forecourt fuel, and ethanol blends (which absorb atmospheric moisture more readily) all introduce water that can cause poor running and fuel-line icing.
A. Yes. BG Fuel System Drier is safe for oxygen sensors and catalytic converters and all standard petrol fuel-system components.
A. BG separates petrol and diesel drier products. The petrol drier (280/281 family) is for petrol. BG also produces a combined drier for both fuels — verify intended fuel type with the listing before purchase.
A. Yes — that is one of its primary purposes. It allows entrained moisture to pass through the fuel system rather than separating out and freezing in the fuel lines or filter.
A. BG positions it as situational — used when moisture is suspected or as a winter preventive on vehicles operated in cold climates or those that sit unused with part-full tanks for extended periods.
