How Many Miles Will £10 of Petrol Get Me?

Estimate how far £10 of petrol could take you using the petrol price and UK MPG you enter.

Estimate your range

Enter the petrol price and your car’s fuel economy to estimate range.

What your result means

Your estimate shows how far £10 could take you at the price and UK MPG entered. It is a fuel-only range estimate; real range changes when price or consumption changes.

Worked example

Using £10, 142p per litre and 45 UK MPG:

Petrol purchased
7 litres
UK gallons
1.55
Estimated range
69.7 miles

The same range model powers the calculator above.

Helpful questions

Does £10 always buy the same distance?

No. The estimate changes with the fuel price and your vehicle’s UK MPG. A different price or measured MPG changes the litres bought and the range.

Is this a return-journey estimate?

It estimates the total distance that the purchased fuel could cover. Plan a return journey against the total distance you expect to drive.

Why might my actual range be different?

The calculation uses your entered price and MPG. Traffic, speed, load, weather and driving style can change real fuel consumption.
