Good numbers. You must have had more downhill driving on your way back.

09 limited MPG questions by milzo

Just picked up my 09 2.5x limited 2 days ago. Drove it from cleveland to toledo, for christmas, which is about 100 miles. My trip is 90% highway. On the way there we averaged 21mpg 75mph and 3000rpm with a strong head wind. On the way back we average 23.4 mpg 72mph and 2700rpm with no wind. The car now has 240 miles. I am diassapointed with these numbers. I've heard that the mileage isn't that great when they are brand new and it gets better after break in. Is that true? Also my car doesn't coast as much as I am used to. It seems when you let off the gas that it immediately starts to slow down. I assume that's due to the 4AT and high rpm's at cruising speed. What's the story, will it get better??? .

Winter mpg is significantly lower than summer. Also, if you are going to match the high mpg reported by some people you will have to slow down to 65-70 mph and drive for efficiency. This means leaving a large enough gap between your vehicle and the one ahead so that most of the time when they brake all you have to do is let off on the gas. Drive smooth and as slow as you can stand without impeding traffic behind you. SUV aerodynamics penalize driving over 70 mph.

Just completed a 400mi trip in my XT and got 25.4mpg. I kept the car between 65-70 with a couple of traffic snarls and a couple of times flooring it to get around some slower traffic. I did up my tire pressure to 35psi before my trip so that might have added to the mpgs, but I do have to say that is pretty weak mpgs for the regular 4 banger, when I 1st bought my XT back in May I went on a 400mi trip right off the bat and got 23.8 and 24.7 on the way back. Check out your tire pressure and up it to 35psi if it's lower.

My '98 improved steadily until around 15k miles, when it peaked.
 
Our '09 is also improving, though that trend stopped once the bitter cold arrived. We're still mid-high 20s, though.

Picked up 09 Forester yesterday (non turbo) Trip today out to New York State (from Providence, RI) trip computer said 23.4,drove 350 miles 16.3 gallons put in = 21.5 actual mpg. Hoping gas mileage was a little better because when I fill up I go to the brim, squeezing every last ounce. Dealer provided full tank at purchase, but I sure it wasn't quite full. Estimating that they were maybe one gallon short, that means actual mpg was probably around 23.
 
I know the vehicle new and a little disappointed, but hoping for better mpg when broken in. I filled up back at the Mass border and have driven another 160 miles and trip computer says 28.8, so I am guessing actual mpg per consumption perhaps in the 27 range.
 
I find trip computers in every car I have owned past several years always optomistic. Plus on the six mile long hill down west of Westfield, MA will always inflate the mpg on a trip. Let everyone know next time I fill up.

Trying to remember.... are you coming out of a Tribeca? Or maybe that was 'baron. I know you had a old Outback at some point.....
 
Anyway, congrats. Squeezing every last drop may result in consistency later on, but I suspect you are probably right on that first tank and put in more fuel than was originally there. I keep a log of fill ups on my vehicles and have it set up such that it keeps a great running average, monthly average, and cost of fuel per mile, etc.

You are right! Had 05 Outback from Dec 04 until Aug 06, put 52k miles on. Got good deal on Demo Tribeca with 10k & had that vehicle until March 08, turned that in with 65k miles & got Nissan Altima Hybrid. Had that car exactly one year turned it in this week with 34k for the Forester.
 
I have kept accurate mileage records on every vehicle I have owned for at least the last 30 years. I don't know why I do it. Get to the gas station record date, mileage, gas put in, temperature, mpg per computer, and actual mpg. Sop when I post mpg on any board, it is accurate!

Congrats.
 
Mileage will improve, since the engine is still very green.
 
I didn't hit peak MPG in my 1998 Forester until 15k miles, and I tracked mileage the same way you do, using an Excel chart.

Wow! Those are impressive miles to rack up in the times you listed. Do you install beds in the backs of them?
