:5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
● The 5W portion of the oil viscosity rating indicates a 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.
● The 30 in 5W-30 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.
