Recommendations for off-road diesel users.
All gasoil in the UK must be manufactured to BS 2869 Class A2. This specification contains seasonal requirements for summer and winter. A fuel certified for use during the summer period is only suitable for that period; winter fuel may be used all year.
These recommendations have been issued following operational difficulties in equipment and vehicles encountered during cold periods or when summer grade fuel may have been left in tanks during winter. They are valid for diesel fuel and especially for non-road diesel (Marked gasoil meeting BS2869 class A2).
These recommendations are to inform off-road diesel users of potential problems that may occur when using the product without respecting the seasonal specification and to make users aware of precautions to take when using gasoil during cold periods.
