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

The expense of driving from Portsmouth to Slough, using petrol as the fuel source, amounts to £12. 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 £6 (£12 divided by 2). With three passengers, the expense drops to approximately £4 per passenger (£12 divided by 3), and with four passengers, it's reduced further to £3 per passenger (£12 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 Slough, approximately 8.4 liters of fuel would be required. This amount is determined by dividing the distance of 69.46 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 £12 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.
 

Diesel cost from Portsmouth to Slough.

The trip with diesel fuel costs 7.6 £ (151p/lt, 62.7 mpg).
For 2 passengers: 3.8 £ (7.6/2) /p.
For 3 passengers: 2.53 £ (7.6/3) /p.
For 4 passengers: 1.9 £ (7.6/4) /p.

Fuel efficiency of diesel and petrol: 

Diesel Fuel: Diesel engines use less fuel than petrol ones. Diesel fuel's higher energy density and diesel engines' superior thermal efficiency are the main reasons. Diesel fuel has more energy per litre or gallon than petrol, hence diesel engines can extract more energy. Diesel engines also have larger compression ratios, improving thermal efficiency. Diesel vehicles get better fuel efficiency and travel farther per gallon or litre than petrol vehicles of equal size and performance. 
Fuel efficiency is lower for petrol engines than diesel engines. Petrol is still an effective internal combustion engine fuel, but it has less energy density than diesel. This means petrol engines may need more fuel than diesel engines to function similarly. In recent years, turbocharging and direct injection have increased petrol engine fuel efficiency, closing the gap between petrol and diesel vehicles. 
Due to their higher energy density and thermal efficiency, diesel engines are more fuel-efficient than petrol engines. Diesel and petrol vehicle fuel efficiency can also be affected by driving habits, vehicle design, and other variables.
