I need heip figuring miles per gallon.?

Question

We have a '89 thunderbird, gage is broke. If i gave him $20 a week how many miles would that give him? $2.19 gallon and about 180 miles a week. I think the fuel capacity is about 22 gallons. Let me know how you figure it to. Or just give me the way to figure it instead of answering. First one to figure gets best answer.

Answer 1

$20 divided by $2.19 = 9.13 gallons

I guess the car can go 18 miles to a gallon, city driving
9.13 gallons times 18 miles = 164.34 miles

If the car can go 20 miles to a gallon, city driving.
9.13 gallons times 20 miles = 182.6 miles

Answer 2

The problem is that you left out a very important part of the equation. You don't know the miles per gallon that the car gets which is different for every car. The way you would figure that out is to fill the tank then drive 100 miles or however many you feel like then fill the tank up again after you fill up the tank divide the number of miles driven by gallons needed to fill the tank back up. That will allow you to figure out how many miles can be driven on $20.

Answer 3

You need to know the exact capacity of the gas tank. Then fill the tank. Drive a few days and refill the gas tank, recording how many miles you drove and how many gallons of gasoline were consumed (that's the amount it takes to fill the tank again) Divide the number of miles driven by the number of gallons used and you can figure approximate miles per gallon. Do this several times and you can get an average.

You always have to fill the tank at the pump and record the miles driven on the last full tank to do this. After you calculate the miles per gallon you can start using a few dollars here and there. But $20.00 a week, when you don't know how much gas the car consumes, could actually cause you to run out of gas in time! You have to know your average MPG in order to drive without a working gas gauge!

P.S.: You don't have to fill your tank and run the car out of gas to figure MPG ... that's just stupid!

Answer 4

This isn't 100% exact, but it will give you a good estimate. Mileage changes depending on driving conditions (ie stop and go vs freeway, which is why the epa gives two different mileage ratings on vehicles)

1. Fill up your gas tank completely. (Fill the gas tank until the pump actually stops itself)

2. Zero out the trip odometer. If there isn't a trip odometer, write down the mileage on the regular odometer.

3. Drive around for a week.

4. Go back to the same gas station, and use the same pump if possible. Fill up the gas tank again.

5. Read the trip odometer reading (or subtract the standard odometer reading from what you recorded the week prior). This will give you the total miles driving by the vehicle.

6. After filling up the gas tank, this will determine how many gallons of gasoline were used. (You should be able to get this straight from the fuel pump)

7. Divide you number in step 5 by the number in step 6 and you will get the miles per gallon that vehicle used that week.

8. If he drives 180 miles/week, divide 180 by the value you calculated in 7. This will help you determine the number of gallons of gasoline that are required per week.

9. Knowing the number of gallons he needs per week and the cost of gasoline ($2.19), multiply these two numbers and you can determine how much money he needs.

Full example:
1. Tank filled completely.
2. Trip odometer zeroed out or taking an odometer reading let's say the odometer reads: 110,193.5
3. Drive around for a week in a normal fashion.
4. Go back to gas station and fill tank.
5. Read trip meter (376.2) or take new odometer reading and subtract it from the reading in step 2 (110,569.7 - 110193.5 = 376.2)
6. Read the number of gallons used to fill up the gas tank from the gas pump. (18.8 gallons)
7 Divide 5 by 6 => 376.2/18.8 = 20.01 miles per gallon.
8. He typically only drive 180 miles per week so 180/20.01 = 8.99 gallons of gas per week (So he uses about 9 gallons of gas per week)
9. Knowing he would use 9 gallons per week * $2.19 per gallon = $19.70 per week (This is the amount of money he would need on a weekly basis)

I made up numbers, but it gives you something to follow as an example.

Some things to remember.
Do not run the gas tank dry, this may damage the fuel pump.
You don't have to wait a whole week, I only used a week as an example the time duration is not critical in determining miles per gallon. (I only used a week as an example)

Answer 5

Here is an easy way to find that out. 1- Fill the gas tank all the way. 2- Set your meter to zero. 3- Drive for a day or two (The way u regularly drive) 4- Fill the gas tank again all the way up. 5- Check how many miles (or km) you drove and check how many liters (or gallons) it took for the tank to fill up. 6- Now divide the number of gallons used by the number of miles you traveled. 7- The result will be ur MPG (Miles Per Gallon)

Answer 6

I would assume that the fuel gauge is broken, and not the odometer. In this event, the next time that you fill up with gas, mark down the odometer reading. Then, when you fill up with gas after that, mark down the odometer reading again. Subtract the first odometer reading from the second odometer reading, this is the number of miles driven between fill ups. Then, take the number of gallons purchased at the second fill up, should be on the receipt or pump read out, and divide the number of miles driven by the number of gallons purchased. This will give you the average miles/gallon that your vehicle consumes.

Answer 7

make sure your tank is actually 22 gallons. After that you need to fill the car up with gas then drive around basically until you run out of gas (keeping track of the miles driven). You then divide the miles driven by how many gallons of gas used (how many gallons the tank holds). The answer is how many miles you will be able to drive with one gallon..... so you multiply the price of gas by the miles able to be driven with one gallon and then you multiply that by 22 gallons and there ya go

Answer 8

total miles on the tank divided by the gallons that went in

Answer 9

WELL RUN OUT OF GAS FIRST LOL SOUNDS BAD BUT MY GAS GAUGE DOESNT WORK . AND ITS SOME WHAT I HAD TO DO AND THEN REFILL AND R3UN OUT OF GAS AGAIN LOL THEN YOU WILL KNOW HOW MUCH GALLONS YOU HAVE USED .OOPS AFTER YOU HAVE RESET YOUR MILIAGE LOL GOOD LUCK !
