Tip of the Week

Snowed In

When the temperature drops, so does your vehicles fuel efficiency, by rates of up to 50 percent. Fuel consumption is at its highest after a cold start and before the engine has had a chance to reach normal operating temperatures, and the colder it is outside, the longer the engine needs to warm up. Driving in snow further inhibits fuel efficiency as tires lose traction and the engine is forced to work harder. But if getting behind the wheel in wintry weather is unavoidable, the following tips will help minimize fuel consumption and maximize safety on snowy roads:

• Carpool. The fewer the vehicles, the safer the roads.
• Scrape snow and ice off all windows, mirrors and lights, as well as the hood, the roof and around the tires. Piled snow can be very heavy, and increased weight reduces fuel economy.
• Check the tire's air pressure. When the temperature is low, tires lose pressure more rapidly. The lower the air pressure, the lower the fuel efficiency.
• Plan the route before starting the engine, aiming for the shortest distance with the least hills.
• Warm up the engine on the road, not in the driveway. Idling for a prolonged period wastes fuel. An engine block warmer will save time and gas by keeping your engine warm during frigid nights.
• Lights. Turn them on no matter time of day it is.
• Allow ample time for the trip, drive below the speed limit, and remain a distance of three car lengths behind the vehicle in front. Brake gently to avoid skidding.
• If possible, park in a heated garage to avoid cold starts.
