Add oil if the indicated level is too low. Make sure the oil conforms to the manufacturer's recommended viscosity.

如果油表显示的油压太低，需要加油，以确保油能符合制造商的推荐粘度。

If air pressure than the standard oil bubble rising fast, explain this oil viscosity is low.

如果比标准空压机油中气泡上升速度快，说明这种油的粘度偏低。

Smaller than the oil viscosity of air, temperature, pollution, and thus can be used for high-speed machinery, apparatus and radioactive devices, but its load capacity than the oil is low.

空气比油粘滞性小，耐高温，无污染，因而可用于高速机器、仪器及放射性装置中，但其负荷能力比油低。

Sweet light crude oil yields the most gallons of gasoline per barrel of oil and since it has low viscosity and low density, it is comparatively inexpensive to pump, transport, and refine.
