So if you drive in a dusty area be sure tochange your oil every 3,000 miles ( 5 000 km) orsooner if the "Change Oil" light comes on.Remember to reset the Oil Life Monitor when the oil has been changed. For more information, see "Engine Oil Life Monitor" in the Index. 1. Engine Oil and Filter Change* -- Always use SH or SG Energy Conserving I1 oils of proper viscosity.
