As drivers watch the price at the pump steadily climb, people are starting to pay more attention to their car's gas mileage, and a recent Freemont Motors blog post gives some tips on how to calculate your vehicle's miles per gallon (MPG).
In the recent post by automotive writer Lauren Baures, she says to learn how to make your gas mileage count, you first have to know how many miles per gallon your car is getting.
Although most modern cars have digital displays that do most of the calculation for you, that number may not always be right, Baures points out.
"The number that is displayed on your dash may not be exactly correct," Baures writes. "Just like a trip computer, these can also be reset giving false numbers or erratic driving may also skew the results."
She suggests using "old school math" to calculate your car's real MPG number. The formula includes miles driven plus gallons used to refill the tank, according to Baures.
Baures says first, fill your car's tank to the cutoff level and reset your trip computer. Next, drive until you need more fuel and then fill back up again to the cutoff level. She tells readers to write down the number of gallons used to re-fill and the miles displayed on your car's "trip counter." Then reset the trip display and after four to five times, you should have an idea of MPH, she said.
