How much does it cost to travel from Christchurch to Portsmouth by car?

The journey, fueled by petrol, comes to £8.6. In this calculation, we've assumed a petrol price of 143 pence per liter and the car's petrol consumption at 37.5 miles per gallon.

For those considering carpooling, with two passengers, the cost per person is £4.3 (£8.6/2). With three passengers, the cost reduces to £2.87 per person (£8.6/3). And for four passengers, it further decreases to £2.15 per person (£8.6/4).

To break it down further, here's how we arrive at the result:

The fuel required is determined by dividing the distance by the car's fuel consumption. For a journey of 49.65 miles, this calculation involves multiplying 49.65 miles by 4.54609 (liters per gallon) and dividing by the car's consumption of 37.5 mpg, resulting in 6 liters of fuel needed.

The fuel cost is then calculated by multiplying the fuel needed by the price per liter. For 6 liters of fuel at 143 pence per liter, the total comes to £8.6.

In conclusion, the fuel cost from Christchurch to Portsmouth amounts to £8.6.


How much fuel a car uses is directly related to how well its engine is oiled. How to do it: 


  • Efficiency: An engine that has been properly cared for and is in good shape works more efficiently, which means it can burn fuel more efficiently and use less of it to make the same amount of power. 
  • Combustion: If the fuel injectors are dirty, the air filters are jammed, or the spark plugs don't work right, the fuel may not burn all the way. This is called incomplete combustion. This wastes fuel and makes people use more of it. 
  • Fuel blend: For the engine to burn efficiently, the fuel-air blend needs to be carefully managed. Any changes from the right ratio, like when an oxygen monitor or fuel injector doesn't work right, can cause the engine to use more fuel than it should. 
  • Mechanical Wear: As an engine ages, parts inside it like piston rings, valves, and seals can wear out. This makes the engine less efficient and causes it to use more petrol. This wear can be lessened with regular upkeep, which can also help keep fuel use in check. 
  • Ignition Timing: If the ignition timing is off, it can cause inefficient combustion and higher fuel usage. This can be caused by a worn distributor or a broken ignition system. 

To sum up, the state of a car's engine is a major factor in how much fuel it uses. For the engine to work well and use little petrol, it needs to be serviced regularly and fixed quickly when something goes wrong.
