Oil viscosity
l The 0W portion of the oil viscosity rating indicates the characteristic
of the oil which allows cold startability. Oils with a lower value before
the W allow for easier starting of the engine in cold weather.
l The 20 in 0W-20 indicates the oil viscosity when the oil is at its
operating temperature. An oil with a higher viscosity may be better
suited if the vehicle is operated at high speeds, or under extreme
load condition.
