#73 of 77 Re: 2008 Focus SES Sedan MPG [sryder32] by auto2009 May 13, 2009 (12:15 pm)
Replying to: sryder32 (Jan 20, 2009 7:40 pm) People seam to assume the computer is wrong but I have found a lot of gas pumps are not accurate. most pumps that I have been to within 10 miles of my house seam to be off by as much as 3/4 of a gallon per fill up. I have found 2 that are within .1 off for a fill up. these descrepancies can make it seam like your car is off but more likley you are not getting the gas you are paying for.

Replying to: auto2009 (May 13, 2009 12:15 pm) I'd agree that sometimes different pumps behave differently about when they shut off when filling the tank, but the amount of gasoline they deliver and what you pay for is certainly accurate as those pumps have to be regularly calibrated and certified.   And even though calculating your mileage is simple (and something I do at every fill-up) a lot of people make basic mistakes when doing so. I recall one person who was looking for a new car, but wanted something that got the same mileage as her old one. She said she was getting 35-40 mpg on her old car, but there was no way that was happening since the EPA mileage estimates on that car were like 25-27 highway. What happened was the very first time she filled the car up, it took about 10 gallons of fuel, so she assumed that a fillup meant she had a 10 gallon tank. When she'd drive a tank almost dry, she'd fill up and then divide however many miles she had driven by 10. Problem was she had about a 15 gallon tank! So while she THOUGHT she was getting 35mpg, she was actually getting 23mpg.   But the basic calculation is simple. Fill up, drive, and at the next fill up, divide the miles driven by the number of gallons you put in the tank. Yes, you can get the occasional "short fill" when a pump shuts off short of really filling the tank which can give you a higher mileage number, but that will correct itself the next fillup when you actually do fill up completely.   I use the mileage calculation as a general guide to the health of my cars. If the mileage suddenly changes lower I sort of go on alert. If it stays low on the next fillup or tow, there may be some problem. But if it comes back to normal, it either was a fillup variation or some change in my normal driving patterns that caused the drop.   But back to my original point, I don't think there's any way that a pump is delivering 3/4 of a gallon less than it says it is. On a 10 gallon fillup that's a 7% error. Just not going to happen on a regular basis.
#75 of 77 Pleased with Focus mileage on first long trip. by sammy3165 Jul 29, 2009 (9:19 am)
We have had our Focus (2009 sedan -SEL) for just four weeks. Around town we were getting about 28.5 to 29.0 per gallon. My wife is an RN and makes short (10-15 mile) trips from visit to visit. This past week-end, we traveled 358 miles from our home in Southwest, FL to Brunswick, GA. I was very surprised and pleased when the car would "only" take 10 gallons of gas when I filled up for the return trip. That 35.8 figure with automatic and cool AC while cruising at 75 mph was really good news. I traded in an Escape that would do only about 25 mpg highways on its best day.
#76 of 77 '04 3-door SVT by jcp123 Oct 28, 2009 (1:15 pm)
I kept track of the '04 Infra-Red SVT Focus I had for 7358,8 miles. In that time:   28,73mpg average 21,22 worst 36,61 best   I noticed that SVT's are fuel-intensive in town, usually getting 22-24ish on a commute cycle, though with some mild hypermiling I usually garnered in the range of 27-28 on my commutes. However, on extended freeway travel, knocking down 33-35mpg tanks wasn't that hard to achieve.
#77 of 77 2003 3-Door SVT by europawill Dec 04, 2009 (9:05 am)
I've been very satisfied with the mpg i'm getting in the SVT. This car has an awesome combination of performance and efficiency.   The car currently has about 70k and was bought new in 2004.   I had flashed the computer at the Ford dealer with the latest profile (I think sometime in 2005).   I've been averaging about 28-31mpg in mixed but mostly highway. Its usually consistently either 29 or 30mpg mixed. I usually drive at an indicated 70-75mph on the highway. I also drive very conservatively in the city and only rarely will I go past 4500k RPM.   Best I've ever recorded was 37mpg on a trip from NY to Boston. I didn't think it was possible but I traveled 283.3 miles on only 7.65 gallons. It was mild weather in the 60's, had the windows closed most of the way and kept the car mostly on cruise control at an indicated 65-75mph (my gps says my speedo is about 7% optimistic so my real speeds were ~60-72mph).   Is this the highest mpg seen on a SVT?
