What's the cost of a drive from Perth to Watford?

The journey, powered by petrol, sets you back £75.3. In this calculation, we're crunching numbers based on a petrol price of 143 pence per liter and a car's thirst of 37.5 miles per gallon. If you're carpooling with a buddy, that's £37.65 each (£75.3 divided by 2). With a trio onboard, it drops to around £25.1 a head (£75.3 divided by 3), and with a full car of four, it's a mere £18.83 per person (£75.3 divided by 4).

Let's dig into the math behind it. The fuel expenditure hinges on the distance covered and the car's efficiency. For this particular jaunt, you're looking at guzzling down roughly 52.7 liters of fuel. Crunching the numbers, that's where the £75.3 total comes from for the trip from Perth to Watford.
 

Diesel cost from Perth to Watford.

The trip with diesel fuel costs 47.6 £ (151p/lt, 62.7 mpg).
For 2 passengers: 23.8 £ (47.6/2) /p.
For 3 passengers: 15.87 £ (47.6/3) /p.
For 4 passengers: 11.9 £ (47.6/4) /p.

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

  1. Petrol:

    • Petrol typically has an octane rating ranging from 87 to 95 in most markets.

    • Octane rating measures the fuel's resistance to premature detonation or knocking in spark-ignition engines.

    • Higher octane ratings are crucial for high-performance petrol engines with higher compression ratios or turbocharging, as they help prevent engine knocking and allow for more efficient combustion.

  2. Diesel Fuel:

    • Diesel fuel doesn't have an octane rating in the same sense as petrol because it's not used in spark-ignition engines.

    • Diesel engines rely on compression ignition rather than spark ignition, meaning the fuel-air mixture ignites spontaneously due to high pressure and temperature.

    • Therefore, diesel fuel is designed to ignite under the high compression conditions found in diesel engines, and its properties are optimized for this type of combustion rather than for octane rating.

In essence, while petrol relies on octane rating to ensure proper combustion in spark-ignition engines, diesel fuel is formulated to ignite under the high-pressure conditions of compression ignition in diesel engines, rendering octane rating irrelevant for diesel fuel.
