If the kinematic viscosity of the base oil is higher than 35 mm 2 / s, the fuel efficiency may deteriorate.On the other hand, if the kinematic viscosity of the base oil is lower than 2 mm 2 / s, the lubricating performance decreases and the evaporation rate is high, and the oil consumption increases. May increase, which is not preferable.
- the pour point which is an index of the low-temperature fluidity of the base oil, is not particularly limited, but is usually preferably 10 ° C. or lower.
