2002 Ford Focus Bad Mileage?!?

drive my Car from work and back, a few stops at light but im running anywhere from 210-235miles on a full tank, my car usally fills up at roughly 10gallons, so thats 21-23mpg.. ?? Why am i getting such poor results.. I recently cleaned the MAF intake, and put a new air filter in, and Fuel filter I also used Fuel system cleaner, and I have a whole new Fuel system with brand new Fuel injectors.. No air leaks I see at all either.. What could be causing this?? I should get 27-31+mpg

Drive slower, less heavy acceleration. read the road, less braking

Reply:you might want to try a tune up, plugs, wires and such. and you might want to go with a higher grade of gasoline. there are more and more additives everyday in fuel and it seems to make efficiency go out the window. Also it may just be getting clogged up from the trip only to work and back, take it on a nice long drive and run the crap out of it. Im not saying to set any land speed records but run it like you stole it!!!!
Reply:I'm thinking maybe your car is just in bad shape...I mean c'mon its American made, what do you expect? lol! Well everytime you fill up...(or once a week)...get that gas cleaner stuff and put it in your tank before you fill up. That should help out with your gas milage. Also, when you are driving in town put it in overdrive. Another thing, when you accelerate do not slam on your gas, ease it, that just wastes gas. Another thing, in the summer...if you actually have a working air conditioner only use it when you are driving over 55mph. When you are driving under 55mph (or in town) put your windows down. Because a/c uses up some of your gas. If you are driving on the highway and your windows are down the air resistance is pulling back on your car and using more gas then you need. I have no idea what would be wrong with your car since you said you use that fuel cleaner, and you got all this stuff fixed. I just have to say your car is probably made with this kinda mileage. Go for a foreign car! But take my advice with the overdrive and the airconditioning. It really helps, especially the over drive, I've saved alot of gas doing that.
Reply:replace your timing belt if you haven't already done so. After 90k miles the timing belt tends to stretch and doesn't keep engine timing stable as it could on a newer belt.
Reply:well first off if your putting all that cash into your car to get a few more mpg its not worth it..get a new whip if your so upset about it
Reply:Every driver will get a different mileage reading, as it depends on your driving habits. Fast starts, ( I don't mean screeching tires, just fast starts) waiting till last minute to apply brakes, driving at steady speed, sudden burst of speed to pass, and different road conditions all have a bearing on fuel mileage.


Did you get the car new? and if so, what was the mileage then?


A set of new plugs might also help, and of course the condition of the transmission, is the fluid lever correct and is does is slip on take off?


If all else fails, and other cars of the same make and model are getting as you say around 30mpg or so, then a new computor might be the answer.


I had a 91 Aerostar and the gas mileage was terrible, about 15 mpg, and regardless what was done it didn't change, until I put in a junk yard computor, alas, 22mpg, I lost a little umph on take off, but very little and the car ran much better.
Reply:..try this... catalitic converters have an annoying subtle way of puuggin up after a few thousand mile, with stuff it hasnt compltly burnt.... next time yur at a stop, dont shift out of first gear for a ways, a 150 yards or so, and reve the RPM's up and let the engin compression blow the crap out of the converter...


You will notice an improvement in performance promptly, and your milage shuld improve as the converter gets it's functions back to some what near it's intended range of functionality.


Drivers who run these newer engins at low RPM's all have simmular complaints. This is as realistic a way of cleaning a converter as there is... it's cheep too, comparitively speeking.
