With petrol prices remaining high, adopting a more economical driving style can help motorists cut fuel consumption noticeably, by as much as 20% on everyday journeys.
Avoid harsh acceleration
Hard acceleration significantly increases fuel consumption. Changing gear at lower engine revs helps save fuel, provided the appropriate gear ratio is used. In cars with automatic transmission, selecting the "Eco" mode can reduce consumption, since the gearbox shifts up earlier and keeps the engine running at lower revs.
Make use of engine braking
Heavy braking means wasted energy. Rather than shifting out of gear when approaching a red light or a point where you need to slow down, engine braking is preferable. Most modern cars have a fuel cut off system during deceleration, which also helps save fuel.
Limit very short trips
An engine uses more fuel when cold. On short distances, consumption rises noticeably until the engine reaches its proper operating temperature. For very short trips, walking or cycling is preferable.
Avoid idling unnecessarily
Once running, an engine continues to burn fuel even when the car is stationary. Consumption can reach around 0.5 to 1 litre of fuel per hour, which is why it is recommended to switch off the engine whenever a wait is expected to exceed 20 seconds.
Use air conditioning and electrical accessories sparingly
A car's electrical systems, such as air conditioning, fans and comfort features, draw power that ultimately comes from the engine. Depending on the vehicle and conditions, using air conditioning can increase consumption by 0.3 to 1.5 litres per 100 kilometres. At the same time, open windows and sunroofs increase aerodynamic drag. At 100km/h, having windows open on both sides can increase consumption by around 0.2 litres. Savings should never come, however, at the expense of safety related systems such as lighting, wipers or windscreen heating.
Remove unnecessary weight and equipment
Extra weight increases fuel consumption. It is estimated that every additional 100 kilograms can increase consumption by up to 0.3 litres. The same applies to roof racks, roof boxes and bike carriers, which affect a vehicle's aerodynamics. When not in use, they should be removed.
Check your tyres regularly
Correct tyre pressure plays a significant role in fuel economy. Using low rolling resistance tyres can save up to 0.5 litres of fuel per 100 kilometres. At the same time, underinflation increases rolling resistance and, in turn, fuel consumption. Even a drop in pressure of 0.3 bar can lead to noticeably higher fuel use.
Don't neglect maintenance
A properly maintained car consumes less fuel than one that does not follow its recommended service schedule. Regular oil changes, using the correct lubricant in line with the manufacturer's specifications, contribute significantly to reducing consumption.
Maintain a steady speed
Keeping a steady speed, both on the open road and in town when conditions allow, helps considerably with fuel savings. Constant acceleration and frequent braking increase consumption, since they demand more energy from the engine. A smoother, more predictable driving style is usually also the more economical one.
