In general, a car requires more petrol (or gasoline) than a bike. This is because cars typically have larger and more powerful engines, which consume more fuel to propel the vehicle. On the other hand, bikes are human-powered or equipped with small engines, such as in the case of motorcycles or scooters, which require significantly less fuel compared to cars.
It's important to note that the actual fuel consumption can vary depending on several factors, such as the size and efficiency of the engine, vehicle weight, driving conditions, and individual driving habits. However, as a general rule, cars consume more petrol than bikes due to their higher energy requirements for transportation.
