The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your vehicle according to this chart:

Ambient Temperature

An oil with a viscosity of 10W - 30 is preferred for

improved fuel economy and year-round protection in the

vehicle.

You may use a 5W - 30 oil if the climate in your area is

limited to the temperature range shown on the chart.
