There’s a myth that re-starting an engine uses more fuel than idling. Actually, it’s the other way around. Idling at stop lights, train crossings, or in the driveway waiting for friends is wasting your fuel. Unfortunately, up until recently all of those situations were unavoidable, but with the Stop and Start Engine System, your v6 gas-powered engine will shut off whenever you aren’t in motion. Over time, you’ll be seeing the difference by saving money on fuel.
