How can I calculate the amount of gas money that an average car would use for a certain number of miles?

Question

How many miles to the gallon does an average car get?

Answer 1

You can't as prices change. Check the MPG instead. When you fill up, set the trip meter. Reset at each fill up & also see if it gets better mileage with a better grade of gas.What the heck, it's only $2 more to fill'er with 91 oct.

Answer 2

Miles / MPG x Cost per Gallon = Your answer

Answer 3

Well thats an interesting question. You would need to narrow your information-what size motor? How many gallon gas tank is it/ How far are you going? Are the miles city or highway? And how much the average gallon of unleaded fuel is where you live. Good Luck.
