Fuel economy (Opel Vectra B)

Warming up the engine

"Full throttle" or warming up the engine at idle speed contributes to increased engine wear and increased fuel consumption.

After starting the engine, move off immediately. Warm up the engine at medium engine speeds.

Uniform speed

Restless driving habits contribute to a significant increase in fuel consumption.

Avoid unnecessary acceleration and braking processes.

Drive in the last gear as often as possible; when driving in the city, you can often engage 4th gear already at a speed of 50 km/h.

At speeds from 50 to 80 km/h, fuel consumption in 4th gear is approximately 25% less than in 3rd gear.

At speeds between 70 and 90 km/h, fuel consumption in 5th gear is approximately 15% less than in 4th gear.

Shift to the next gear as soon as possible, and downshift only when the engine no longer runs perfectly.

Idling

The engine consumes fuel even when idling.

It makes sense to stop the engine already during stops longer than 1 minute. Five minutes of engine idling corresponds to one kilometer of travel.

Forced idle mode

During the forced idle mode, the fuel supply is automatically cut off, e.g. when driving downhill or when braking.

During this mode, do not accelerate or disengage the clutch so that the fuel shut-off system can operate to reduce fuel consumption.

Shift gears in a timely manner

High engine speed values increase wear on vehicle components and fuel consumption.

Do not increase the rotation speed to high values. Too high a speed on individual gears or steps increases wear of vehicle components and fuel consumption.

Driving by the tachometer helps save fuel. Try to drive the car at low engine speeds in each gear (approx. between 2000 and 3000 rpm) and at a uniform speed.

High speed

The higher the speed, the higher the fuel consumption. When driving "at full throttle" you use a lot of fuel.

Releasing the accelerator pedal slightly results in significant fuel savings without significantly reducing speed.

If you drive at only 3/4 of your maximum speed, you can save up to 50% of your fuel without significant loss of time.

Tire pressure

Under-inflation of tires results in increased rolling resistance, increased fuel consumption, and increased tire wear.

Additional consumers

Turning on additional power consumers increases fuel consumption.

Additional consumers should be disconnected (air conditioning, heated rear window, additional headlights, etc.), if their work is not required.

Automatic transmission

"Full throttle", kickdown, selecting sport mode and excessive manual gear shifting lead to a sharp increase in fuel consumption.

After selecting D, the gearbox operates in an economical mode. You can drive in the D stage almost always, with a smooth press on the accelerator pedal, an early switch to gears with economical consumption occurs.

Roof rack, ski holders

Roof racks and ski holders can increase fuel consumption by approximately 1 l/100 km due to increased air resistance.

It is recommended to remove them when not in use.
