How to use
Cost per mile is just the fuel price divided by your MPG. Multiply by your annual miles to see the yearly hit. A small MPG improvement saves more than you might expect on high-mileage driving.
FAQ
Is a higher MPG always better?
For fuel cost and emissions, yes — higher MPG means fewer gallons per mile. But total savings also depend on how many miles you drive and the price you paid for the car.
Why does my car show lower MPG than the EPA rating?
EPA figures are lab estimates. Real driving — cold weather, short trips, highway speeds, heavy loads, and tire pressure — typically lands 10–20% below the sticker.
Do US and UK MPG mean the same thing?
No. The UK (imperial) gallon is about 20% larger, so an identical car shows a higher number in UK MPG than in US MPG. Always check which one a source uses.
