13. Fuel recommendation
1. Diesel oil (only apply to diesel vehicle) : only diesel oil of which cetane value is not less than 45 according
to GB252 standard can be used. Sulfur content should not be more than 0.2
％
.
2. No. 0 light diesel oil: Suitable for the zone where venture rate is 10
％
and minimum temperature is higher
than 4°C.
3. No.-10 light diesel oil: Suitable for the zone where venture rate is 10 percent and minimum temperature is
more than -5°C.
4. No.-20 light diesel oil: Suitable for the zone where venture rate is 10 percent and minimum temperature is
more than -14°C.
5. No.-35 light diesel oil: Suitable for the zone where venture rate is 10 percent and minimum temperature is
more than -29°C.
6. Natural gas (only apply to Natural Gas Vehicle ): use natural gas of which methane value is low to 65.
14. Oil/lubricant quality and specification recommendation
Engine oil
Prefer using the engine oil whose quality is equivalent to or higher than level CF-4 or CH-4 of American
Petroleum Institute API, or refer to the engine specification.
Part of engine oil used for lubricating the piston will be burnt out (consumed) during the engine running.
Engine oil must be replaced in certain period because of high temperature effect and the oil combustion
product interfusing in the oil, especially the chemical additive in the oil will cause "abrasion" of the oil.
This kind of abrasion depends on working condition of engine, quality of fuel and engine oil; therefore
there has different oil changing interval. (Recommended oil changing interval is 12000km.)
Engine oil viscosity
Since oil viscosity fluctuated with temperature, so the ambient temperature of engine working area is very
important to select viscosity grade (as shown in the figure). When temperature exceed lower limit, it may
decrease cold start capacity of the engine but will not make any damage to the engine.
Higher sticky engine oil may cause the engine difficult to start, so the ambient temperature of the engine
starting is the main reference for selecting viscosity of the winter engine oil. Selecting multifunctional
engine oil may avoid oil changing caused by temperature fluctuation.
HINT:
Never add any additive to above engine oil and different kinds of oil should be avoided using at the
same time (oil mixture must be the same grade oil and it is recommended to replace in time).
