Petrol and diesel owners could save as much as “half a gallon” of fuel by pressing one switch found in almost all modern vehicles. John Wilmot, CEO and founder of LeaseLoco.com, explained that using start/stop technology is crucial if motorists want to cut down on costs and conserve their fuel tanks.
Start/stop tools automatically shut down a car’s internal combustion engine when the vehicle is stationary, such as at traffic lights or waiting in traffic. The engine then immediately restarts when motorists press down on the clutch or release their brake pedal.
The tool can be turned on and off from the car’s dashboard or infotainment screen, with many individuals frustrated at the system and deciding to deactivate it. But, John stressed this was a mistake with road users to cut their fuel consumption if they stick with it.
He said: “While you’re in traffic or sitting at traffic lights, your car still consumes fuel especially if you’re not using the start/stop feature. According to the RAC, the average family car can use up to half a gallon of fuel per hour when left idling. Turning the feature on and allowing your engine to turn off automatically can save fuel and reduce unnecessary consumption.”
John added: “The feature uses technology to detect when a car is stationary or out of gear and automatically shuts off the engine. Not only does this improve fuel efficiency but it also protects your engine which can be worn out due to idling.”
The tool is most effective when travelling in city centres, where road users are more likely to sit idling in heavy traffic. Stop/start systems tend to only work when the engine is warm, ensuring that every restart is as efficient as possible. This reduces the often high fuel consumption recorded after a "cold start" when the engine hasn’t been used.
The RAC explained: “Stop-start is a feature found in almost every petrol and diesel car made in the last few years. It's also a controversial one, with many drivers finding it annoying and disabling it.
“But, used correctly, stop-start really can save you fuel. Most experts agree that if you are going to be stationary for 10 seconds or more, then letting your engine shut off and restart is more fuel efficient than leaving it idling.”
