Well stated. It's the "how we drive" that is the main factor on what we get for MPG. My son and I can drive the same car and get a 5 MPG difference, even when the driving times are essentially the same. Also, often not mentioned is the use of E10 -v- E0 fuel as that does make a difference. Then there are the use of A/C, remote start, etc... factors that come into play. My son gets about 22/23 MPG and I get about 27/28 MPG on average in an urban environment - preheat the car for about 7/8 minutes each morning using the remote starter. Overall, I was hoping for 30 MPG; however, what we are getting is not too far off and not terrible considering it's winter and I use E10 fuel.

Overall, I'd say that the 2012 Impreza provides about 6 MPG higher over my 2008 OBS, in all cases. Not the full EPA *Estimates*; but well within the *Ranges* presented on the sticker.

If you want to see some real bad deviations, compare the MPG of various Hybrids and EVs when the temperature is less than 32 or greater than 90 degrees Fahrenheit - both in the city and at 70+ MPH.

Using EPA as a baseline for reality is fail. Debating about it here is just stupid.

Inability to drive "boring" is not the cars problem.

Go fix the broken things like alignment or driving style first. If you still have a problem, visit the dealer. If that gets no where, call Subaru. If that gets no where, call the EPA. If that gets no where, buy a new car.

... or come here and endlessly whine about it. It is pretty entertaining after all.

Being that i only have 1000 miles on this Crosstrek i am going to step away from this conversation. Hopefully with the change of oil to synthetic and the addition of a K&N air filter i might have better results.

Also, I am not sure the gauge in the car is that accurate for MPGs. I am gonna do a few full tanks and calculate it myself to be 100% sure.

I am also going to check the mileage gauge and make sure it is accurate. If anyone is familiar with honda back in 2000-2005 there were several cars noted to have a issue with the odometer. When you drove 1 mile it was actually reading on the odometer 1.2 or so.

What i am saying is maybe its not that far off maybe its something else or maybe the car just needs to be fully broken in. Whatever the case......to be continued when more data is available.

I think it's Idemitsu that makes the oil for Subaru, and I don't think it's a Group IV full synthetic. There are only 3 or 4 of those, afaik. There is a loophole that allows some non-Group IV oils to be called full synthetic. Going to Amsoil Signature full synthetic may help...

As far as I know 0w20 ONLY comes in full synthetic.

That's the mantra. However, 0w20 can come in what is legally classified as "full synthetic" but is not 100% Group IV oil. That's why it's possible to get an inferior "full synthetic" oil. Here is some good info:

Actually, my idea involves everybody staying together.

Anyhow, I stated 4000 miles on my car. I stand corrected. Actually 4900 after yesterdays running around. Anyway, 31.6 with mixed driving. About 50/50.

Somewhere back in another thread, I had done the calc on my car. Turns out GPS miles and gallons put into the tank matches my dash reading. After several times getting consistant results, I just go with the dash now. Of course YMMV. I would not assume all are accurate based on mine though.

Filed an official complaint with Subaru this morning. The Cust Service guy I spoke with actually told me that he has a co-worker with the same exact issue. Do I believe everything the guy told me, honestly I don't but here is what he said anyway.

His co-worker has a 2013 Impreza with the CVT and his mileage was 22+/- combined and he was not very happy. He complained to everyone that would listen to him had the dealer check it multiple times. They told him he needed to get to 10,000+ miles for the car to "learn how he drives". Well, the guy is now close to 16,000 miles and he still isn't happy but his mileage has improved to 28mpg +/-.

He then suggested that we continue driving and it should slowly improve as we get closer to 10,000 miles. I told him that is complete BS and why should I waste just under 1 yrs worth of driving miles and get cr@p mileage? I explained that there is no possible way that this could be the Subaru expectation considering that is almost 1/3 of the average life span of a new car for the original buyer. Look at a lease that is generally 3 yrs/36,000... who would ever lease a car if this were the case?

He is going to contact my dealer and get back to me tomorrow with where we are going to take this. I would love to give them the car for a week and get a loaner as someone racks up some miles on it and sees what they get for mileage.

Will post where this goes from here.

In the manual there is language to the effect that it may take 7k or 10k for the engine to properly break in. They might use that to counter your claims for low mpg will get the exact wording when I get home.

I got a very similar line when I called to complain about my car burning oil. I too told them that it was bs expecting people to be "breaking in" for 10,000 miles. well I'm at 20k and my oil problem hasn't gone away.
I like your point about leases. I actually asked them what they tell people who are leasing the cars.

(get out of jail free card, your car needs 7k or more miles before its fully broken in sir)
11-7

Engine oil
NOTE
. The engine oil consumption rate is
not stabilized, and therefore cannot be
determined until the vehicle has tra-
veled at least several thousand miles
(kilometers). Even after break-in, when
the vehicle is used under severe driv-
ing conditions such as those men-
tioned in the Warranty and Mainte-
nance Booklet, engine oil is consumed
or deteriorated more quickly than un-
der normal driving conditions. If you
drive your vehicle under these severe
conditions, you should check the oil
level at least at every second fuel fill-up
time, and change the oil more fre-
quently. Please refer to the Warranty
and Maintenance Booklet for more de-
tails.


Chapter 8-2
Fuel economy hints
The following suggestions will help to save
fuel.
. Select the proper gear position for the
speed and road conditions.
. Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as
possible.
. Do not pump the accelerator and avoid
racing the engine.
. Avoid unnecessary engine idling.
. Keep the engine properly tuned.
. Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on the
driver's side. Low pressure will increase
tire wear and fuel consumption.
. Use the air conditioner only when
necessary.
. Keep the front and rear wheels in
proper alignment.
. Avoid carrying unnecessary luggage or
cargo.

Thanks for the informative and productive post. I too am on LI - having same issue as you, had to travel to Toms River NJ to get the exact car I wanted though.... Filed several complaints myself and playing the waiting game. I feel your pain.

Keep us posted and if this thread gets too annoying as the other one has, just Private Message me. Would love to share information to hopefully reach some sort of resolution. Bye the way.. travel from West Islip to Uniondale EAB/Rekson Plaza, everyday for years, 97 buick v6 did same trip getting 26mpg, 2010 VW GTi same trip got 30+, 2013 Impreza CVT can't break 28MPG, all Hand Calc. So based upon my consistent travel habits, purchased and expected to at least easily break 30+mpg with this car, based upon reviews, advertising, and HP etc.... Needless to say ,, very dissapointed.

Bottom Line - purchased car expecting to improve my situation only to go backwards. I dont understand why so many on here want to dispute what we are living with, like we are making it up or something. Just want to drive responsibly, put recomended gas in my car, do proper maint and be happy. I check my tire pressure, keep my car Immaculate, check oil, etc... and KNOW HOW TO DRIVE EFFICIENTLY!! If I didn't I would be at my Boss 302 MPG's. What dealership did you buy from/dealing with? Ty
Wolverines!!

I believe the problem is the lower torque provided by the 2.0l. I you "slo-go" on the acceleration, you might, repeat might get something close to your expectations. Reality is that you will not; sad to say, but true from my experience.

vwgti123 we purchased from Metric Subaru in Huntington. Where are you bringing your for service?

I am off Thurs this week and plan on driving the car. I will fill up in the morning, drive back/forth to Long Beach and see what sort of mpg I can get by driving as some have suggested... basically "granny" mode. lol Just curious how it will do. I will refill once I get back home to get the numbers.

You can gear around torque - it's the hp that's lacking...

Going to bring mine to either Hassett, Wantagh, or Donaldson's, Sayville, Not sure yet. Have a list of things that need to be looked at. Would rather take it in on a weekday, weekends usually have just oil change techs. Good Luck, keep us posted. Ty

Regardless what Subaru say about running on lower Octane gas one thing I've found is my Impreza runs noticeably better for drivability mileage and power running exclusively on the Higher of Octanes eg 95 or 98 RON / US 91 / 93 MON.

My butt dyno concurs. I've been running 91 octane in my car for the last few tanks, and it seems almost like night and day. I think a good part of that is due to a reduced (or zero) ethanol content. I haven't run enough tanks to confirm that there's a fuel consumption improvement (although the preliminary calculations would suggest so), but it seems to pull a lot more authoritatively from a complete stop.

I suspect it's all due to the no ethanol factor. My cars also run more smoothly, but the mpg is less, by about 3 or 4%.

Now the no ethanol factor, that's a different story. I have a hill on my way to work, called La Bajada, and in my Corolla I can make it up in high gear cruise control with no ethanol gas, but with ethanol it drops 10 mph below the set point and shuts off the CC.

My CVT Impreza, of course, just winds up to about 5,000 rpm and gets less than 10 mpg.

You realize power is dependent upon torque and RPM right? They aren't mutually exclusive.

That's why you can gear around torque. E.G. half the torque and twice the rpm, or one tenth the rpm and 10 times the torque, is the same horsepower.

Maybe so but the FB20 has a reasonably high compression ratio of 10.5:1 so am wondering if the management is retarding some when using the lower Octane fuels, hopefully an engine / fuels expert can chime in ?
