Drive the speed limit - you get better fuel efficiency. This is the EcoMinute and I’m ES. Traveling at 55 mph will give you up to 21% better mileage than when you drive 65 mph or 70 mph.
For every 5 mph you drive over 60, it’s like paying an additional 24 cents a gallon. Also, drive steadily. Slowing down or speeding up wastes fuel. Think ahead when approaching hills. If you accelerate, do it before you reach the hill, not while you're on it. Avoid tailgating - the driver in front of you is unpredictable.
