How can you determine your mpg?

Question

I do not have the owners manual to my car and have just gotten a new job out of town. I've never really thought about how much gas it uses before because I don't travel much but now I would like to see if, with the price of gas so high it's worth it or not to be driving that far every day.

BTW: It's a 2000 Audi T4 Quatro

Answer 1

To find your actual gas mileage, reset the little odometer (there will be a button near the spedometer that resets it) next time you fill your gas tank. When you fill up again, look at the mileage on that odometer, and divide it by the number of gallons of gas you just put in the tank (not by the size of the tank). That will give you your average mpg.

Answer 2

It doesn't make any difference what kind of car you have. Drive until the "low-fuel" indicator comes on. Fill the tank completely (best to just let the auto shutoff stop the pump, and don't top it off). Write down the mileage (you can write down how many gallons and fraction of a gallon if you want, but mainly tp compare it to the next fill-up).

Drive until it is about the same low-fuel point. Fill up. Write down the mileage and the gallons. Subtract the previous mileage from the new one. That shows you how many miles you have driven. Divide that number by the gallons you just put in. That's your miles per gallon. If you do this 3 or 4 times, you'll have a pretty accurate measure of your average MPG. Remember, the number will change if you take a long trip as opposed to city driving or a combination.

Answer 3

To figure out your miles per gallon, you need to fill up your tank while doing this to be accurate.

1. Write down your odometer mileage or reset your trip meter to zero.

2. Fill up your car.

3. Drive around.

4. Next time you fill up your car, take note of how many gallons it took AND either your odometer reading or your trip meter.

4a. If using the odometer reading subtract the first reading from the second. This and/or the trip meter reading will be how many miles traveled.

5. Divide miles traveled by gallons just bought. That is how many miles per gallon you get.

Newer cars have this built in.

Answer 4

I usually do an average. Fill up the tank, drive a few hundred miles, write down you beginning mileage and ending mileage. Now fill up the tank again. Subtract ending miles from beginning miles and then divide by number of gallons on the 2nd fill up.

Then repeat the process. THis should give you a pretty good estimate of your mpg.

Answer 5

get a full tank of gas, drive till you need more gas.

check how many miles you have driven on that tank (ex 200miles)

refill the tank (how much did it take to refill the tank) 15 gallons

200 / 15 = 13 mpg

do this several times and take and average 12+13.5+13/3= 12.8 avg mpg

it's a little crude but it work

and check the manufacturer recomended higway and street mpg

Answer 6

Fill your tank and set your trip odometer to zero (0). Drive normally until the next time you need to fill your tank again. When you fill your tank, write down what your trip odometer says (example: 325.6 miles). After you fill your tank, take a look at how many gallons you needed to fill the tank (example: 13.339 gallons). Divide the number of miles by the number of gallons. Example 325.6 miles divided by 13.339 gallons = 24.41 MPG (miles per gallon).

Answer 7

Here's how to tell your mileage in any vehicle:
-fill it up completely. when the pump shuts off, hang it up, don't go to the next dollar.
-write down your miles. If you have a trip meter, reset it.
-drive until you are a 1/4 tank or below. the further you drive, the more accurate.
-fill it up again. write down how many gallons it takes (down to 1/10th)
-write down your miles again and subtract from your first number, or if you used the trip meter, just write it down.
-divide the miles driven by the gallons of fuel, and there's your MPG!

Answer 8

Let your car get to almost empty, then fill up. Keep track of # of gallons used to fill. Then set your trip odometer to zero. Let car get to almost empty again. Divide number of miles travelled by gallons of gas used. This will equal your mpg. Of course, it can vary by several things such as city vs. highway miles, did you run the air, etc.

Answer 9

Start with a full tank, record the numbers from your odometer, drive happy, refill the tank, see how many gallons , record that, record the odometer, and divide the difference in miles by the gallons used.

Answer 10

This is one way: Fill your tank up with gas, reset the trip miles on your odometer, and next time you fill up with gas, divide the miles by the gallons you used to fill up.
