The best way to measure mpg would be to fill up, reset your trip and drive as many miles as comfortably can to being empty, then fill up again. Divide trip miles by gallons filled=accurate mileage.

 

My lovely 2002 legacy sedan just got 27 mpg, 40/60 highway city. I was driving like a madman though, my first time with actual power in a car. It seems bad but my Oldsmobile, the previous car, got about 18mpg 75/25 highway/city. Now I am playing the 'no more that 2500rpm, neutral at lights and down hills' game, and driving on eggshells. I'm hoping for 30+ this time around...

 

Getting ready for my trip cross country to college, and a new car was a must. I'm hoping for 27 mpg with a loaded car and highway driving, but saving the money for 23.

Keep up with highlighted and you'll never get to 30.

Really? Why? Isn't it better to just coast downhill at like 750rpm instead of 1500? Same with lights...i coast downhill and just keep rolling down gentle grades around here for like a half mile...seems like it would work to me but I am not really a car guy... Care to explain? I have an AT, not manual. Thanks.

I see... Anything else?

I believe the fuel injectors (on the AT at leat) shut down when the vehicle is coasting in gear. This, in theory, gives you an infinite real-time mpg.

The car is not for sale anymore. Who snuck in and bought it?

I have an 05' Legacy sedan 2.5i, 16,691 miles on the car... just came back from a trip of about 1200 miles, Best mpg for a tank was 40mpg... That of course was with no traffic on a road with a posted speed limit of 55mph. ( i always just set the cruise and go). Average miles per gallon for the entire trip was 31.5, combination of highway and city, with lots of hills and driving most of the time at 75 to 80 mph.

whae gas prices started going up last fall, i stared filling up mid point in my 200 mile commute each week. gas was cheaper on the road than it was in the big city. if filled up at home , got on the hiway , drove 100 miles , and filled up again i got 32mpg @ 65-70 mph. 97obw a/t. that's great. but driving 100+ miles each week around town brings my average mpg down to 25. i'm happy with that as well.

 

i'm impressed with the gas mileage number for new cars, they're all 30+. how do they do that and can we do it to a 10 yera old car.???

So you have fell for the marketing. Notice how they only state the highway mileage, and never say its on the highway (x car gets up to 32mpg..). No one quotes the city mileage. number anymore in advertising.

New cars are New, that how. They are lighter, they are geared differntly, some of them highspeed is just barely off idle. If you want mileage that high, you have to make comproises. you wont find any 4wd car getting as high a mileage as subaru. Go to 2wd you drop a few 100 lbs of gear, and a few more 100 in the unibody since it doesnt have to be as strong.Also the smaller and lighter the car, the less likely its going to lst well into the 200,000 mile range.
