Avoid extensive idling to warm up the engine. Start driving as soon as the engine is started, but avoid rapid acceleration. The engine will warm up faster under a light load, and the exhaust emission equipment will begin to function sooner. A car uses extra fuel when it accelerates. Be alert for slow-downs and red lights.

Air conditioning dramatically reduces fuel economy. Both settings can reduce the air conditioning load and save gas. All rights reserved. Material from this site may not be published, broadcast, rewritten or distributed. A Lee Enterprises subsidiary.
