Sunoco Optima is an ethanol-free unleaded petrol, designed to be storage stable for extended periods.

Why Use an Ethanol-Free Fuel?
Ethanol is hygroscopic, which means it attracts water. High levels of ethanol in the fuel leads to increased moisture in the engine, which can cause rust and corrosion issues. The ethanol itself is also corrosive to aluminium, bronze and zinc typically found in carburettors. Both of these issues are compounded by long periods of non-usage.


Sunoco Optima is specially formulated to be kinder on gaskets, o-rings, and other fuel system components compared to unleaded petrol. It also contains detergent additives for engine cleanliness, as well as anti-oxidants and corrosion inhibitors to extend storage life. When stored in air-tight opaque fuel containers, Optima should remain storage stable for 3-5 years.

All hazardous goods orders received before 12pm will be guaranteed to be dispatched the same day (depending on stock) and sent via a freight company that provides a standard 3 day signed delivery service*. For an additional cost, the option of a next day service is available throughout the majority of the UK. However, we cannot accept responsibility for orders that may be delayed in transit. Due to their hazardous nature, all fuel orders must be signed for on delivery. All routine deliveries are made during Monday to Friday. Some routes may be subject to ta longer delivery timescales.

All our fuels come in UN approved steel drums. All drums have a 2 inch BSP bung, they are designed for safe transport and storage but do not pour very well. To avoid spillage, it is best to use a pump to decant your fuel. We have a couple of different pump options which are available in our web shop. It is best to keep unused fuel in the drum supplied with the drum bung sealed tight. Race fuels will only really deteriorate if vapours can escape or moisture can get into the drum. For this reason, we would not recommend leaving race fuel in your fuel tank for an extended period of time – this is particularly important if the fuel in question contains ethanol. Any drained fuel is best kept in a separate container to the fresh, unused race fuel.

Try and store your fuel where it is not exposed to wide temperatures swings, i.e. outside.
