Oil viscosity: Must be selected according to the lowest temperature and highest temperature in the weather. Such as 10W-40 viscosity of the oil (W for winter), it represents the maximum temperature of 40 degrees Celsius, the minimum temperature of minus 20 degrees Celsius. In China, with the exception of the three northeastern provinces, other regions generally use 10W-40 engine oil to apply throughout the year. The three eastern provinces can also choose to use according to the temperature change, such as about to enter the winter and then use 5W-30 oil that can cope with temperatures below minus 20 degrees Celsius.

How does the sprinkler choose engine oil?
The oil level, as long as it meets the minimum level required on the water truck model, you can choose a higher level of oil according to your ability. Oil level from low to high E, F, G, H, J, L and other levels, manufacturers generally require the lowest level in the instructions, such as the general automotive requirements to use SE or SF level (where S refers to the use of automotive engines Engine Oil) If SG grade oil is required, at least SG grade oil must be used. If the actual oil level is used and there is no requirement in the specification, it will easily form more carbon deposits in the combustion chamber, affecting the performance of the engine and increasing fuel consumption.
