Is 8 liters per 100 kilometers a lot?

[DeCameron]

Consuming 8 liters per 100 kilometers is within the normal range. However, this also depends on factors such as vehicle model, engine displacement, and powertrain system, as well as road conditions. For micro or compact cars, 8 liters would be considered high fuel consumption. For family sedans, this is normal. For mid-size vehicles, 8 liters is actually quite low. There's a direct correlation between vehicle weight and fuel consumption - it's said that reducing vehicle weight by 10% can decrease fuel consumption by several percentage points. Improving engine thermal efficiency is crucial. Modern gasoline engines typically achieve thermal efficiency (the ratio of fuel energy converted to useful work) above 30%, while diesel engines exceed 40%, which explains why diesel engines generally have lower fuel consumption than gasoline engines.
