Spark Plugs - Even though most current GM vehicles have 160,000 km (100,000 mi) service intervals for spark plugs, if your vehicle is at that point
in its life, have the spark plugs changed to assure proper running and continued efficient, trouble free operation. Refer to the applicable Maintenance
Schedule for spark plugs service intervals on Chevrolet Aveo, Optra, Epica, Pontiac Vibe, Wave and Saturn Astra.
Changes In Driving Habits:
^
Slow Down, Drive Smoothly - Avoid quick/full throttle acceleration from a standstill in town and high cruising speeds on the interstates. While the
optimum MPG for highway cruising speed varies from vehicle to vehicle, faster is almost always worse. If your vehicle is equipped with a Driver
Information Center that displays Instant Fuel Economy, select that read out and vary your cruising speed while on the highway. The display will
change continuously with uphill and downhill sections but you should quickly be able to identify on level ground the speed range that your vehicle
does the best in.
^
Empty Your Trunk - Avoid leaving unnecessary items in your trunk. It takes power to move increased weight and that means more gasoline
consumption and reduced performance. While the change may be slight, multiplied by thousands of miles, it all adds up.
^
Avoid Extended Idling - There is no need to idle your engine till it reaches operating temperature. Idling wastes fuel.
^
Combine Trips - Your vehicle uses much more fuel when the engine is cold. This is especially true in the winter months when the engine will take the
longest to warm up. Combine errands or trips so that the vehicle only needs to warm up once to encompass many different stops.
