Does using cruise control increase fuel consumption?
Does using cruise control increase fuel consumption? I have been a keen user of cruise control for many years and it is the only extra I ever have installed on any new car.

Yes because it robs you of the sensitivity of control with your right foot. Motorways are surprisingly undulating. If you leave the meter on instant consumption you can see the economy dive on an incline if you maintain speed. But if you lift off a little bit and lose maybe 5mph, you might maintain reasonable economy. On a descent, the opposite happens. When you could increase speed at no increase in consumption you find the cruise control braking the car.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
