How to calculate the gas usage in vehicle
To calculate gas mileage, it will take a cycle of filling up the gas
The first time you fill it up, fill it up. You do this, so that when
you fill it up the second time, you top it off exactly as you did the
first time, so it is a similar fill up.
Once you fill it up the first time, while you are sitting at the pump,
reset your mileage meter on your vehicle, or write down the current
mileage on the odometer (100 miles for example) you wonâ€™t need to
register how much gas you bought, gallons, at this fill up.
When you go back and fill it up the second time, you will again, write
down the current mileage (400 for example)
Then you will figure up the difference in the mileages you wrote down
400 minus (-) 100 = 300 used milesâ€¦..if it took 10 gallons to fill it
up the second time you will divide the mileage by the number of
gallons that it took the second time to top it back off, to the max.
this will give you the exact mpg that your car gets.
In the example case it would have been
400-100=300 used miles /divided by 10 gallons = 30 MPG. Hope this helps.
We do this EVERY time we go on a trip, just to see how much mpg that
the car gets, because we know it getâ€™s better on the open road,
compared to around town.
