When I first started driving I drove slow bc I thought it would save gas, then I started driving faster when a friend told me you use the same amount of gas whether you drive slow or fast (as long as it’s the same distance), you just would be driving fast for a shorter amt of time and driving slow for a longer amt of time, but at the end you burner thru the same amount of gas. Is this true?

Air resistance is one of the main forces your engine is fighting against when driving your car. However, the relationship between your speed and drag isn’t linear. Doubling your speed causes air resistance to multiple by 4. The best thing you should think about to improve your gas mileage is driving smoothly and not accelerating or braking hard. Say there’s slower traffic ahead. Accelerating hard and braking hard when you get to it uses more gas than coasting there does. In my experience the best mpg I can get is when cruising at 40-50 mph on state highways where I almost never have to brake.
