The Fuel Diamond is an amalgam of heavy metals with a military history which stabilises octane levels in fuel, preventing the petrol in your car, motorcycle, boat, lawnmower, generator etc from going stale.
It's not unusual for modern petrol to deteriorate after only two months. If you store your vehicle or fuel for long periods, including over winter, your petrol can go stale, resulting in poor starting and compromised performance.
Increasing amounts of ethanol in petrol risk damaging your fuel system. During a long lay up, fuel can emulsify, forming a gel in your carburettor or injectors which can harden to a varnish-like coating. The Fuel Diamond prevents this emulsification, protecting your whole fuel system.
E5 (5%) ethanol is mandatory for 95 octane petrol in the UK. It is soon set to increase to E10 (10%)
