Gas Oil for off-road mobile equipment in the UK - manufactured to BS 2869 Class A2 - 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.
Watson Fuels has issued the below recommendations 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 Gas Oil meeting BS 2869 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 Gas Oil during cold periods.
