I have a 2009 Ford Focus, I keep an eye on the little light that tells me what my average miles per gallon is. It usually stays in the 30 to 32 mgp range but yesterday I noticed that it had dropped to 28 mpg. I had about 3/4 tank of gas in the car. I drove it about 3 miles and the mpg continued to drop down as low as 24 mpg. The gas hand did not move and still it shows just under 3/4 tank. I have not driven the car more than 5 miles today but the mpg continues to drop. What could be the problem?

Depends on miles per gallon of vehicle. Average mpg of say 15 mpg would take 15 gallons to travel 225 miles.(15x15=225). At $2.29 per gallon @15 gallons=$34.35. So figure out mpg of your vehicle and do the math.

You would need to check with a local garage for repair prices.
To find your average mileage, fill up the tank, write down the mileage, then do it again at around 200 miles. Divide the mileage traveled by the number of gallons used. I would recommend filling up after you have used about 8 or 9 gallons to prevent running out of gas. You can't go by the federal mpg numbers because everybody drives differently.

That should be acurate to about a few miles, it take the average miles per gallon to find its reading, a good test would be to put a gallon of gas in the car and drive until it tells you you have 2 miles left and then go get gas, this way if you run out you will be able to put gas in, i think this would be a good way to test the system. good day.

It just depends on your tank size. You probably get about 15 -18 miles per gallon. 13 gallon tank would be around 200 miles. 15 gallon tank around 232 miles.

If you are getting 18 miles per gallon you are doing very well. The normal MGP is 14-17 miles per gallon, so no problems there. Is the transmission fluid at the proper level? When was the last time your transmission fluid was changed?

You could fill the tires with Nitrogen but it will cost about $15 a tire. You will gain 1.5 - 2 miles more a gallon. Big trucks were made for pulling and hualing only. If your looking at gas mileage then you need a focus.

I have the same issue of low gas mileage. My 2008 Kia Rondo with V6 (2.7Lt) gets 20-21 mpg in average. Even for highway mileage, it is around 21-22mpg. Very poor gas mileage. Disappointed. I hope it would improve in the future.

The previous post is untrue! MFA means MultiFunktions Ansiege (pronounced AAN-zeeguh).
This is a German- Americanism for Multi-Function Indicator.

The MFA displays the time, time driven since the ignition was started, miles driven since the ignition was started (trip miles are displayed under the odometer), miles per gallon, average miles per gallon, and outside temperature. I think that's it. If you click the little button on the underside the wiper switch, you can toggle between 2 different trackings. If you HOLD that button, you can re-set the avg. mpg's (but not the current mpg's, they are calculated every 30 yards), time driven, miles driven. Contrary to the previous poster's solution, it does not actually indicate anything is wrong with your car! (but they were right about scrolling through the indications with the side rocker switch) the malfunction indicator is on the cluster, it is a little engine block with a lightning bolt through it. It usually means you need an oil change. If it blinks, you have a catalytic converter problem. Hope this helps.
