Driving directions from Glasgow to Swansea
How much does it cost to drive from Glasgow to Swansea with petrol?
Let's delve into the expenses of a road trip from Glasgow to Swansea. The journey using petrol will set you back 72.6 pounds. Now, let's walk through how we arrived at this figure.
Firstly, we consider the price of petrol, which is 143 pence per liter. Next, we take into account the car's fuel consumption rate, which stands at 37.5 miles per gallon.
Now, suppose you're carpooling. If there are two passengers sharing the ride, each person will contribute 36.3 pounds (£72.6 divided by 2). With three passengers, the cost per person drops to around 24.2 pounds (£72.6 divided by 3). And if there are four passengers onboard, each person chips in 18.15 pounds (£72.6 divided by 4).
Let's delve deeper into the calculations. To determine how much fuel is needed for the trip, we rely on the distance and the car's fuel efficiency. The distance between Glasgow and Swansea is approximately 418.82 miles. So, to cover this distance, the car will require roughly 50.8 liters of petrol. We obtained this value by dividing the distance by the car's fuel consumption rate of 37.5 miles per gallon and then converting it to liters.
Once we have the amount of fuel needed, we calculate the total cost. Multiplying the fuel quantity (50.8 liters) by the price per liter (143 pence) yields 72.6 pounds. Therefore, the fuel cost for the journey from Glasgow to Swansea is 72.6 pounds.
Diesel cost from Glasgow to Swansea.
The trip with diesel fuel costs 45.9 £ (151p/lt, 62.7 mpg).

For 4 passengers: 11.48 £ (45.9/4) /p.
When comparing diesel fuel and petrol (gasoline) fuel in terms of octane rating, there's a significant distinction:
-
Petrol (Gasoline): Typically has an octane rating between 87 and 95, crucial for preventing engine knocking in spark-ignition engines.
-
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.
