Petrol cost per mile

Fed up constantly shelling out for petrol? We've rounded up the cheapest cars to fuel that will cut your petrol cost per mile to the minimum

You budget for monthly payments for your car, but running costs can really make or break a motorist (and their bank account). While insurance and servicing costs are big hitters in the area of running costs, the actual cost of travelling every mile in fuel terms is often overlooked. But it could be your biggest car expense depending how far you drive.

The beauty of this is that understanding the cost of petrol per mile is easy enough and once you have a rough idea of how much it costs for your car, you can see just how much you could save if you bought a new, more efficient vehicle. Or even if it's now time to change up to a plug-in car to take advantage of low electric car cost per mile figures.

Do you often find yourself getting to the end of the month and wondering where all your money has gone - without having bought anything particularly extravagant? It's possible your current car is draining you dry in fuel bills. Some older cars - even those with smaller engines - aren't the most fuel-efficient, especially if you spend a lot of time driving around town or zooming along the motorway in a car that's not really designed for it.

But it's not always about the car your driving; there are other ways of reducing your fuel bills and stretching those pennies that extra mile.

How to reduce your fuel costs

If you have an older car, trading up for something newer and more economical could slash your fuel costs. The higher your annual mileage, the more you could save. But there are other ways to reduce the size of your fuel bill.

Aside from picking a more economical car, planning your journeys a little and making one big supermarket trip every week, for instance, rather than going three times for a couple of things every time, could put more cash in your pocket.

It's also important to consider what kind of journeys you're undertaking, if you're spending hours tearing up and down motorways you're likely to be better off with an economical diesel engine instead.

All cars should come with a claimed fuel economy figure from the manufacturer, but while in the past these may have been artificially high, all cars now have to be sold with far more accurate, easily achievable figures, using a test referred to as WLTP in place of the old NEDC one. We've rounded up the most economical petrol cars assessed on the latest test below.

Petrol costs: least expensive cars to fuel

When looking for a petrol car with the lowest costs per mile, fuel economy is king; the further a car can travel on a gallon of petrol, the less it is going to cost you per mile. As a result, cars which are small, light, aerodynamic and powered by frugal engines come out best. If you want - or need - something a bit bigger, however, fear not.

To avoid a list of tiny city cars, below are some of the least expensive petrol cars per mile. These include everything from city cars, superminis and family hatchbacks to small SUVs, people carriers and even a sports car or two. What isn’t included, though, are electric cars of any type with all those listed below petrol-powered only. For the cheapest electric cars per mile click here.
