The expense of driving from Penarth to Cwmbran using petrol amounts to £3.6. This computation is based on a petrol price of 144 pence per liter and a car's fuel efficiency of 37.5 miles per gallon. For those considering carpooling arrangements, the cost per passenger decreases with more occupants. With two passengers, the cost per person is £1.8 (£3.6 divided by 2). With three passengers, it's approximately £1.2 per person (£3.6 divided by 3), and with four passengers, it's £0.9 per person (£3.6 divided by 4).

To delve deeper into the calculations, we can explore the fuel cost calculation. This is determined by the distance traveled and the car's fuel consumption rate. For this journey, approximately 2.5 liters of fuel would be required. Multiplying this by the petrol price per liter results in the total fuel cost of £3.6 for the trip from Penarth to Cwmbran.

Diesel fuel and gasoline (gasoline) fuel in terms of how well they use fuel: 

Diesel Fuel: In general, diesel engines use less gas than petrol engines. This is mostly because diesel fuel has a higher energy density and diesel engines are better at using heat. Compared to gasoline, diesel fuel has more energy per litre or gallon. This means that diesel engines can get more energy from each unit of fuel. Diesel engines also have higher compression ratios, which makes them even more thermally efficient. Because of this, diesel cars usually get better gas mileage and can go farther on a gallon or litre of gas than gasoline cars of the same size and speed. 
Petrol (petrol): Diesel engines use less fuel than petrol engines in general. Even though gas is still a good fuel for internal combustion engines, diesel fuel usually has a higher energy density. This suggests that gas engines might need more fuel to work as well as diesel engines. The difference between petrol and diesel cars has become smaller, though, thanks to improvements in petrol engine technology like turbocharging and direct injection. 
Overall, both diesel and gasoline engines can be used to get good gas mileage, but diesel engines tend to be better because they store energy more efficiently and cool down faster. But how people drive, how the car is built, and other things can also affect how much fuel a diesel or gas car uses.
