- Engine size and efficiency: Larger engines typically use more petrol than smaller ones. For example, a car with a 2-litre engine might use around 10 litres of petrol per 100 kilometres (62 miles) driven, while a car with a 1-litre engine might use only around 5 litres per 100 kilometres.
- Vehicle weight: Heavier cars use more petrol than lighter ones. A car that weighs 1,500 kilograms might use 20% more petrol than a car that weighs 1,000 kilograms.
- Driving style: Aggressive driving (such as rapid acceleration and braking) uses more petrol than smooth, steady driving.
- Traffic conditions: Driving in stop-and-go traffic uses more petrol than driving at a constant speed on a highway.
- Tyre pressure: Underinflated tyres can increase petrol consumption by up to 10%.
- Air conditioning: Using the air conditioning can increase petrol consumption by up to 15%.
- Ethanol content: Petrol with a higher ethanol content (such as E10) can reduce petrol consumption by up to 5%.
On average, a typical passenger car uses around 8-10 litres of petrol per 100 kilometres driven. However, this can vary significantly depending on the factors listed above.
