Do plug-in fuel saving devices actually work?
Can the 'Eco-Chip' fuel saving device plugged into the OBD2 socket cause damage to vehicle systems, including PHEVs?

We have not tested the EcoChip fuel saving device, but would be hesitant about using one, particularly on a car with a plug-in hybrid powertrain.
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.
