A petrol vehicle is a type of motor vehicle powered by an internal combustion engine that runs on petrol (gasoline). Petrol engines work by mixing fuel with air, compressing it, and igniting it with a spark plug to create energy that drives the vehicle. These vehicles are widely used for private cars, motorcycles, and small commercial vehicles.

As of November 25, 2024, the average price of petrol in the UK was 135.37 pence per litre, making it a relevant consideration for motorists evaluating fuel costs.
