Saving fuel: driving and maintenance tips

Saving fuel comes down to driving style and vehicle maintenance. Here are practical tips to reduce consumption without changing your car.

Driving: smoothness and anticipation

Smooth driving (progressive acceleration, anticipatory braking) can reduce consumption by 10 to 20 % compared with aggressive driving. Use engine braking instead of the brake pedal when possible. Avoid jerky driving and revs that are too low in a high gear (lugging) or too high in a low gear (over-revving). On the motorway, moderate speed (110–120 km/h instead of 130) noticeably reduces consumption. Air conditioning and accessories (lights, demister) increase consumption: use them in moderation.

Maintenance: tyres, filters, oil

Under-inflated tyres increase rolling resistance and consumption: check pressure regularly (manufacturer’s chart). Clogged filters (air, cabin) can reduce engine performance and increase consumption. Correct engine oil (manufacturer’s specification) and correct level help efficiency. Regular diagnostics (no fault putting the engine in degraded mode) avoid hidden over-consumption.

Order of magnitude for savings

According to studies, smooth driving and proper maintenance can reduce consumption by 15 to 25 % compared with aggressive driving and a neglected vehicle. On a 50-litre tank, that means several litres and tens of euros saved per year. My Auto Check-up helps you spot symptoms that can increase your fuel bill (check engine light, smoke, loss of power).
