Due to paraffin separation, the fluidity of diesel fuel decreases remarkably as the temperature decreases. For this reason, diesel fuel is divided into two types, “summer” and “winter”.

The effective limit of “winter” diesel fuel during cold-weather periods is rated at -15 C. In extremely cold weather, it is recommended that regular petrol (not premium or “high-test” petrol) be mixed with the diesel fuel up to a maximum concentration of 30 %. In order to minimize the reduction in performance, be sure to mix in only as much regular petrol as is absolutely necessary.

When travelling in a foreign country, be sure to obtain information regarding the diesel fuel in general use in that locality. Use of a “flow improver”, which can be obtained at most petrol stations, is recommended.

CAUTION

(1) Because the fuel is highly flammable, mix the diesel fuel and regular petrol only inside the vehicle’s fuel tank.
(2) If possible, put the regular petrol into the fuel tank before putting in the diesel fuel.
