HANDLING IN COLD SEASON
Replacing the Engine Oil
Use an engine oil with a viscosity adequate to the outside temperature as engine oils
will thicken with low outside temperatures, resulting in starting difficulties.

Fuel
When using in cold regions, select fuel depending on the ambient temperature.
NOTE
The specifications of diesel fuel vary depending on the season and the region.•
Fuel Requirements (for United States and Canada Only)
Diesel fuel is sensitive to temperature. All diesel fuel has a certain amount of paraffin
components, which are high in energy value and help improve fuel economy. But,
when temperatures are below -7°C (20°F), the paraffin components begin turning into
wax flakes. If temperatures are low enough, these flakes can obstruct the fuel filters
and stop fuel from reaching the engine.
At low temperatures, wax flakes are more likely to form in Type "B" (2-D) fuel
than in Type "A" (1-D) (or "winterized" Type "B" (2-D)) fuel. For best operation at
temperatures below -7°C (20°F), use Type "A" (1-D), or Type "B" (2-D) blended with
Type "A" (1-D) for winter use. When temperatures are consistently below (or near)
-18°C (0°F), use Number 1-D if at all possible. Bear in mind, however, that even
Number 1-D fuel will form wax flakes when temperatures are extremely low.
In cold weather, your fuel filter may become clogged (waxed). To unclog it, move the
engine to a warm garage area and warm the filter to between 0°C and 10°C (32°F
and 50°F).
