#58 of 185 48 mpg
Aug 13, 2008 (9:06 am)
I have a 2003 Ford Focus ZX3 manual. I drove 380 miles from Binghamton, NY to Pittsburgh, PA going mostly the speed limit or under, ranging from 45-50 mph in construction zones, 55 mph zones and 65 mph interstate. I got 48 mpg with gasoline from Mobil. I didn't use A/C or the cd player. I had the windows up and the fan going at 2.
On the way back, I used gasoline from BP and got all the way back to Binghamton without having to stop for gas. I only used 8.8 gallons of gas for 382 miles so I got about 43 mpg. There were alot of stop and go construction on the way back on 80 E. I was amazed I could get so much mpg from a Ford Focus.
I didn't use the brakes very much and was able to coast down the hills without using the accelerator.
When I used to go 75-85 mph, I only got 30 mpg. When I went 95 mph, I only got 26 mpg. For regular city driving, I get about 29 mpg.
#59 of 185 Anyone swapped out the airfilter?

I was wondering if anyone who swapped in a K&N Air filter got better fuel econ.
#60 of 185 Misa, what does a CD player have to do with mpg?...
Aug 16, 2008 (8:42 pm)
I advise using your AC since you paid for it and it doesn't cut mpg much. Also, from what I read an air cleaner does not effect mpg much when it becomes dirty. Using a electronics such as a CD player in a car will not drop your mpg due to using battery power.

I have an 08 Focus, 5 spd...mostly expressway driving, usually 75 mph, and usually get 33-34 mpg (display usually says 35). I think driving around the speed limit, you should be able to get 38 or so- my wife took it to SC, and said she thought there were times they averaged 40. I usually accelerate briskly as well...someday, I'll try to have patience and just see what I can average for a week...80 miles round trip to work.

>>Wow my MPG suffered after going to 100% highway. I recently moved and I go about 70 (yeah I follow the speed limit) on the freeway for my entire commute and I'm down to 29-30 MPG. I was getting better fuel economy going local with some minor gridlock. Very odd
Not odd, really. This actually sounds just about right. Don't underestimate the effect of excessive speed on fuel economy. You may not think 70 is excessive, but try dropping to 60 and see your fuel economy dramatically increase. I'd say about 10% better.
#63 of 185 Actual numbers
Nov 25, 2008 (6:14 pm)
I keep religious tally of fuel economy, being somewhat of a statistical nut. Here's my numbers, for a 2007 2.0L SES 5-speed run almost exclusively with E10. (EPA revised rating of 24/33).
As of 11-21-08, with 29560 miles on the clock:
Best tank: 40.84 mpg
Worst tank: 29.66 mpg (first tank)
Average: 34.76 mpg
Most miles on a single tank: 421
Total spent on gas over 15 months: $2,786.39
#64 of 185 2009 Focus Sedan 5 Speed with Revised "Overdrive"
Nov 26, 2008 (8:59 am)
I just purchased this so can't report on gas mileage yet - I have just 200 miles on it. Almost all the miles on it are mine - I was the first and last to test drive it, when I pulled it out of the lot it had 6 miles on it, when I purchased it, it had 26 miles on it - I test drove it twice, first time to see if I liked it, second time two weeks later to make sure nothing had happened to it since the first test drive (like clutch abuse from another test driver - yeah, that can happen).
I re-set the digital gas mileage readout after the dealer filled the tank and also zeroed the trip meter.
Generally I don't have a special break-in routine, I believe that my normal commute, which combines about 10% city miles and 90% mixed freeway miles (high speed, slow and go, occasionally some stop and go) is a good break in routine, provided I don't lug it (let the rpm's go too low and then try to accelerate with heavy throttle, instead of downshifting) or use more than 3/4 throttle (and only use more than 1/4 throttle after fully warmed up).
Since I intend to drive from SF to LA this afternoon, though, I decided to try to accelerate the break-in period with some more aggressive driving than usual. I mention this because it drags down the gas mileage, which I will report in a moment.
To accelerate the break in period, I first varied my commute to include more city driving. I drove to a more remote on-ramp, which includes a hill climb. City driving has more acceleration and coast down (cool down) cycles and is supposedly better for seating the rings. It also varies the RPM, which is the only admonition in the owners manual (which basically states, don't drive too hard or at one constant speed).
Second, I accelerated more aggressively and ran the rpm higher during slow and go traffic and on the streets. Instead of limiting my self to 1/4 throttle, I ran it up to 1/2 throttle; instead of shifting at 2,500 rpm, I ran it up to 4,000. These brief, harder runs supposedly "buff" high spots (of which there are few in modern engines) without creating excessive heat or galling. Keeping the rpm away from the 6,500 rpm assures there is plenty of oil flow (after this is broken in, I will replace the factory oil with Mobil 1 full synthetic, which is reportedly very superior to conventional oils in maintaining an oil film if there is reduced flow at very high rpm, and it is also more resistant to thermal breakdown at high rpm when the operating temperatures can peak and there isn't a lot of oil flow to carry heat away).
My goal was to drive it harder than my usual break-in to accelerate break-in, but no so hard that I would be stressing the engine. In short, compared to my normal mild-mannered driving style, I drove the new car more the way the typical aggressive American driver drives routinely.
All of the above tend to reduce mileage, so I haven't been expecting much in the first couple of hundred miles, but to my surprise the computer is registering 34.5 mpg!
Well, I'll be putting about 800 freeway miles on it over the next three days. I'll report back on both computer indicated mileage and on calculated mileage. As the earlier poster notes, the sweet spot for mileage is usually 50-60 mph, but interstate speeds are more like 70-80 mph. I'll try to keep it down to 70, but almost all my other cars have been 2-4 mpg lower for interstate trips than for my commute (which has much lower average speeds).
Finally - my thoughts on break-in. In my experience, modern motors are still breaking in at 15,000 miles, but for all practical purposes (driveability, gas mileage, power) the process is mostly completely by 7,500 miles. Of the first 7,500 miles, the first 200 are MOST critical, but from 600 to 1000 miles any critical break-in buffing is complete and the car can be driven hard (many owner's manuals state a 600 to 1,000 mile "cautious" break-in period, followed by no precautions). So I'm going to take the next 400 miles "easy" and will welcome any pre-Thanksgiving traffic that will slow down the interstate. After I hit 600 miles - essentially for my return trip - I'll just drive it completely normally. If I don't run into Thanksgiving slowdowns today, I'll vary my interstate driving speeds by spending some time in the turtle - I mean truck - lane and some time in the car lanes, which gives me a range of from 50 mph to 80 mph to assist the break in process. I considered changing to Mobil 1 before the trip, but the Motorcraft 5-20 oil that Ford developed is such a superior lubricant that I think it will work just fine, if I keep my throttle, top speeds, and steady speeds in the break-in mode.
#65 of 185 2008 Focus SES Sedan MPG
Jan 20, 2009 (7:40 pm)
I bought this car in September 2008, and I live in Raleigh, NC. I now have 6800 miles on the car. When the weather was warmer, I would get about 31 MPG. Now with the colder weather, I get about 29 MPG. My drive to and from work each day is 30 miles, 85% of which is highway at 75 to 80mph. Aside from work, I do errands with the car, which is more like 50% stop-and-go and 50% highway.
One thing I notice is that the car's self-proclaimed Average MPG is always over stated. It consistently says I'm getting at least 3 MPG more than I calculate at each fill up.
The MPG is "okay" in my opinion. Other cars that I considered (and test-drove) before buying Focus were the Honda Fit, Toyota Yaris and Corolla, and Nissan Versa. The Focus had the most comfort, quietest interior, and more features than the others for about the same price. So I'm happy overall. In fact, I love the little thing! Just wish the MPG were a little higher.

I know it would be difficult, however, If you drop the 75-80 down several mph, you will see mid -thirties mpg. EPA mileage estimates are not based on your 75-80.
My experience with the trip computers ( in a ford probe ) some years back was similar to yours, actual mpg was about 3 less than indicated.

Stick shift or auto?
