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 and zinc components such as carburettors. Both of these issues are compounded by long periods of storage between uses.
Sunoco Optima is specially formulated to be easy on gaskets, o-rings, and other fuel system components. It also contains detergent additives for engine cleanliness, as well as anti-oxidants and corrosion inhibitors to enhance storage life. When stored in air-tight, opaque fuel containers, Optima should remain storage stable for 3-5 years.
- All petrol equipment and vehicles that may not be used on a regular basis
- Petrol stabilisers are not needed when using Sunoco Optima

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.
