BG Ethanol Fuel System Defender® (2136, 177ml) protects petrol engines against the degradation caused by ethanol-containing fuel such as E10 — now the standard grade of unleaded petrol in the UK. Ethanol-blended fuels are prone to oxidative degradation that produces gum and varnish deposits in the fuel system, particularly during periods of infrequent engine use.
BG Ethanol Fuel System Defender® inhibits the free radical oxidation mechanism responsible for this degradation, keeping intake valves, fuel injectors and combustion chambers clean. A corrosion inhibitor protects metal fuel system components from the corrosive effects of ethanol, while a moisture dispersant prevents water separation — a common problem with ethanol-blended fuels in storage or seasonal-use vehicles such as motorcycles, boats and garden machinery.
Add to the petrol fuel tank every 3,000–5,000 miles (4,800–8,000 km). Also available in 325ml (SKU: 213E).
Add to the fuel tank at the recommended dose for optimum results. Suitable for use in both passenger cars and light commercial vehicles across a wide range of engine types.
Sealer fibres are six to ten times smaller than the narrowest passages in the cooling system — seals leaks without clogging radiators or heater cores.
Delivered in 2–3 working days to mainland UK. 30-day returns on unopened items.

A. It prevents ethanol-related deposits and corrosion in petrol fuel systems. The 177ml bottle (2136) treats one full tank of 23–38 litres — typical passenger car capacity.
A. 177ml (2136) treats one full tank of 23–38 litres — typical passenger-car capacity. 100ml (213100E) suits smaller tanks; 325ml (213E) covers larger tanks or multiple treatments.
A. Add to the fuel tank every 3,000–5,000 miles (4,800–8,000 km): 50ml for tanks up to ~11 litres, 100ml for 15–23 litres, 177ml for 23–38 litres of petrol.
A. Ethanol-blended petrol degrades through free-radical oxidation, forming deposits on intake manifolds, ports, valves, injectors and combustion chambers. BG Ethanol Fuel System Defender inhibits that oxidation and keeps the system clean.
A. BG Ethanol Fuel System Defender is effective for all ethanol-blended petrol grades including E10, E15 and E85 — relevant for all UK pump petrol now that E10 is the standard grade.
A. Yes. The product is safe for oxygen sensors and catalytic converters, and prevents the increased emissions that result from ethanol-related fuel-system deposits.
A. Defender (213) targets ethanol-related oxidation and deposits in the fuel system overall. Corrosion Preventer (212) forms a protective coating on fuel-system components against ethanol acid corrosion. They are complementary.
A. Yes. It is an excellent fuel stabiliser — preventing fuel degradation and gum/varnish formation during storage. Suitable for seasonally-used petrol vehicles and equipment.
A. BG states it restores fuel economy where the loss is caused by ethanol-related deposits. Mechanical or sensor-related fuel economy issues are not addressed by additives.
A. BG recommends it specifically for vehicles running on ethanol-blended fuels, as a periodic preventive treatment (every 3,000–5,000 miles). Daily E10 use is exactly the application BG targets.
