How many miles can you drive on a 55 gal at mpg?

To determine how many miles you can drive on a 55-gallon tank, you need to multiply the fuel efficiency in miles per gallon (mpg) by the number of gallons. For example, if your vehicle gets 20 mpg, then you can drive 1,100 miles (20 mpg × 55 gallons = 1,100 miles). Simply replace the 20 with your vehicle's mpg to calculate the distance for your specific situation.
