Driving for Better Fuel Economy Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible... Engine Oil Life System The engine oil life system calculates engine oil life based on vehicle use and displays a DIC message when it is necessary to change the engine oil and filter.

Avoid idling the engine for long periods of time. When road and weather conditions are appropriate, use cruise control, if equipped. Always follow posted speed limits or drive more slowly when conditions require. Keep vehicle tires properly inflated. Combine several trips into a single trip. Replace the vehicle's tires with the same TPC Spec number molded into the tire's sidewall near the size. Follow recommended scheduled maintenance. 1-23 Resetting the Oil Life System 1.
