Storage and handling
Opal fuel has the same storage requirements as regular unleaded 91.
The storage life of regular unleaded fuels is one year when stored under shelter in a sealed container. Once a seal is broken the fuel has a storage life of six months at 20 °C, or three months at 30 °C.
Same storage requirements as regular unleaded 91.
If stored in an open container or fuel tank, the storage life is reduced to one month. This can be extended by topping up with one third of fresh fuel, which restores volatile components that have evaporated. When storing fuel always make sure you use fuel containers that are stamped as meeting AS 2906 and store fuel in a safe, dry place that doesn't have large temperature changes.
