1. FUEL
(1) Fuel Selection
In the cold zone, the fuel might be frozen resulting in hard engine
starting; therefore, select a suitable fuel for such engine operation.
Use ASTM 975 No. 2-D fuel if you expect temperature above –7°C
(20°F).
Use Number 1-D if you expect temperatures below –7°C (20°F).
If Number 1-D is not available, a "winterized" blend of 1-D and 2-D is
available in some areas during the winter months.
Check with the service station operator to be sure you get the properly
blended fuel.
