How much is the expense of driving from Portsmouth to Swansea?

The expense of driving from Portsmouth to Swansea, using petrol as the fuel source, amounts to £32.2. This calculation derives from considering the petrol price as 143 pence per liter and the car's fuel efficiency at 37.5 miles per gallon. When carpooling with two passengers, the cost of the trip per passenger is halved to £16.1 (£32.2 divided by 2). With three passengers, the expense drops to approximately £10.73 per passenger (£32.2 divided by 3), and with four passengers, it's reduced further to £8.05 per passenger (£32.2 divided by 4).

To delve into the details of the calculations, the fuel cost computation is reliant on the distance traveled and the car's fuel consumption rate. For the journey from Portsmouth to Swansea, approximately 22.5 liters of fuel would be required. This amount is determined by dividing the distance of 185.7 miles by the car's fuel consumption rate of 37.5 miles per gallon, and then converting from gallons to liters using the conversion factor of 4.54609 liters per gallon.

Multiplying the fuel needed by the petrol price per liter results in the total fuel cost of £32.2 for the trip. This breakdown illustrates the impact of various factors, such as fuel price and consumption rate, on the overall cost of the journey, providing insights for individuals planning similar trips and requiring budget estimates.
 

 

The fuel economy is highly sensitive to the state of the vehicle. In this way:

The effectiveness of the engine's fuel combustion and its overall consumption are both improved with regular engine maintenance. Maintaining your engine with routine oil changes, air filter replacements, and tune-ups will keep it running at its best.

Problems with the fuel system, including blocked injectors or a malfunctioning oxygen sensor, can cause petrololine to burn improperly and increase consumption. Preventing such problems requires regular maintenance and rapid repairs.

Problems with tires: When the tires are worn down or not inflated properly, the vehicle has to use more energy (and fuel) to go forward because of the increased rolling resistance. You may enhance your fuel efficiency by changing worn-out tires and keeping them properly inflated.

Aerodynamics: If the body of the vehicle is dented or has panels that aren't flush with the body, airflow will be disrupted and aerodynamic drag will increase, resulting in increased fuel consumption. The best aerodynamic performance is possible with a well-maintained vehicle body.
