How much does a trip from London to Brighton set you back in petrol costs?

The answer: £25. In this calculation, we're considering a petrol price of 143 pence per liter and a car's fuel efficiency rated at 37.5 miles per gallon. Carpooling with two passengers reduces the cost per person to £12.5 (£25 divided by 2). With three passengers, the expense drops to approximately £8.33 per passenger (£25 divided by 3), and with a full car of four, it's just £6.25 per passenger (£25 divided by 4).

Now, let's dissect the numbers behind this. The fuel cost is determined by the distance traveled and the car's fuel consumption rate. For this journey, you'll need approximately 17.5 liters of fuel. Crunching the figures, that's where the total of £25 comes from for the journey from Harrow to Cardiff.
 

Diesel cost from Harrow to Cardiff.

The trip with diesel fuel costs 15.8 £ (151p/lt, 62.7 mpg).
For 2 passengers: 7.9 £ (15.8/2) /p.
For 3 passengers: 5.27 £ (15.8/3) /p.
For 4 passengers: 3.95 £ (15.8/4) /p.

When comparing diesel fuel and petrol (gasoline) fuel in terms of octane rating, there's a significant distinction:

  1. Petrol (Gasoline): Typically has an octane rating between 87 and 95, crucial for preventing engine knocking in spark-ignition engines.

  2. Diesel Fuel: Doesn't have an octane rating as it's not used in spark-ignition engines. Diesel engines rely on compression ignition, so diesel fuel is formulated to ignite under high pressure, making octane rating irrelevant for diesel fuel.
