In more detail, the result is obtained:
Fuel needed = Distance / Car fuel consumption = miles * 4.54609 / carConsumtion = 111.05 mi * 4.54609 / 37.5 mpg = 13.5 liters
Fuel needed = 13.5 lt
Fuel cost = Fuel needed x Price per liter = 13.5 liters x 143 pence per liter = 19.2 £

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