How much is the expense of driving from Preston to Dumbarton?

The expense of driving from Preston to Dumbarton, using petrol as the fuel source, amounts to £34.7. 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 £17.35 (£34.7 divided by 2). With three passengers, the expense drops to approximately £11.57 per passenger (£34.7 divided by 3), and with four passengers, it's reduced further to £8.68 per passenger (£34.7 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 Preston to Dumbarton, approximately 24.3 liters of fuel would be required. This amount is determined by dividing the distance of 200.41 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 £34.7 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 Preston to Dumbarton.

The trip with diesel fuel costs 21.9 £ (151p/lt, 62.7 mpg).
For 2 passengers: 10.95 £ (21.9/2) /p.
For 3 passengers: 7.3 £ (21.9/3) /p.
For 4 passengers: 5.48 £ (21.9/4) /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.
