Some weeks I treat myself to more accel, and am disappointed in the lower mpg. Then I remind myself of the modded Talon running 16.5 psi, and getting 18 (eighteen!!!) mpg! Hell, my SV650 will drop to 30 mpg if I really get on it, hard! It's typically only 45 mpg. The biggest killer to mpg in this car is wind. I drive thru farm country, and a tailwind can easily give me 3-5 mpg more on the tripmeter. |

Completely baffled
Quote:
I am not sure if this is a bunch of BS, but he did say when he drove the car he noticed the RPM drop off at 40MPH and did notice the RPM increase and engine drag when going downhill. He said to give it a month and see if there is any improvement. Unfortunately I did not have a chance to get on the accelerator for the 40MPH issue and there were no significant downhill events on my way into the office from the dealer. Is there any way for me to actually tell if the service dept really did reset everything, or am I just taking his word for it? One other question, does the terrain (gain/loss in altitude) during my commute really have that big of a negative effect on my MPG? I still see my Avg MPG when driving in "CITY" type conditions in the low teens, and I am not getting on this car at all, in fact I feel like I am babying this thing too much. Is this really how I have to drive to see decent MPG averages? |

NH Dealer - Oil Change
My first oil change was $53.90....I am thinking that is going to be the norm in MA and NH.

When approaching a hill allow the car to slow down then when going down a hill acclerate. Keeping a constant speed is nice but to get the best mpg you have to be aware of the terrain |

For hills, I've had good results climbing with moderate to heavy throttle around 1800-2200 RPM and maintaining about 1500 RPM in gear with zero throttle on descents. If you do it right, you won't use any fuel on the way down.
If your city driving consists of crawling through traffic jams, nothing but a hybrid will give you decent numbers. In those conditions, the A/C penalty is huge. All cars get zero MPG when idling and this car idles more efficiently than most. Few engines will use less fuel than a 2.0 spinning at 650 RPM. As for topping off, don't do it. You'd think if pretty much every gas station posts signs telling you to use less of their product, they'd have a good reason for it. Last edited by Commander Keen; 05-15-2012 at 11:12 AM. |

I never click after the pump auto shuts off the first time. In the manual it also says not to do that. It's kind of an obsessive compulsive thing to do, lol. Since I am keeping track at each fill-up I want to be consistent also.

The Combined fuel average is not the same as either the City or Highway mileage, it is a number halfway between printed on the EPA section of your window sticker that represents the expected average fuel economy for mixed driving conditions. Not the best data, but all we have got is Fuelly: the average 2012 Subaru Impreza on Fuelly is achieving 27-30mpg Combined fuel use. Now explain how you can win a Class Action lawsuit when the average driver is achieving the EPA approved Combined Fuel Economy printed on the sticker approved by the EPA? You also would need to be achieving probably way lower than 20mpg city to have a case, because the expected range on my label shows: CITY MPG 25, but just underneath that big number is the small print, Expected Range for most drivers 20 to 30 mpg. |

I have a 2012 impreza sport premium, and my avg mpg read 27.9 this morning when I walked in to work. Half highway, half city. I have less than 1k miles on it though.

I don't worry about being exact about the fill up and the auto-stop at the pump isn't necessarily consistent anyway. In the end as long as you track gallons pumped and miles driven you'll get a proper overall average. |

- break-in miles - mileage with cars with CVT with older programming - cold weather miles - MT and CVT mileage is combined, no way to filter out for the transmission you have (that I can see). Considering all that, the Fuelly-reported mileage is reasonable. I think the Fuelly numbers will go a bit higher with summer driving and as people get more break-in miles. |

Granted the 2012 Outback has been out a bit longer than the 2012 Impreza so more of those cars would have longer break in periods but I found it interesting to see the Impreza so far under the EPA combined MPG while the Outback was above. |

Also note the high percentage of very high percentage highway miles on the cars that actually get close to the EPA "mixed" mileage. And its maybe something to consider that if you single out other brands/models and just single out the 2012 reports, those averages should include just as much break-in time. |

Hopelessly incomplete (more when I get home) but I had to report on the first leg f my first highway trip. Very pleased:
77 miles and computer shows 40.2 mpg. Was 41.1 when I left highway and then encountered 3 miles of stop and go. Was as High as 42.6 after 40 miles but rolling hills dropped the average. I was diligent to keep 60-65mph as my speed. Not bad! |

just as a side note....Im about to break 13K on my HB Limited CVT PZEV....and I would say yes...it does have an extended breakin period...I saw steady increase in avg MPG after my first oil change, again at around 7K and at 10K.....my commute is 106 miles round trip each day.....car delivered 17 Dec....have not checked on TSB updates.....and my MPGs seemed to have leveled off now after passing through 10K.....Im averaging 31ish.....have seen a high of 33.4 for a full tank.....which I allow to click off at the pump..then fill slowly again till the next click off....all my calculations are manually done.....my low avg since delivery was 26.7 and my high as stated.....
hwy/city on commute....80/20 ish....speeds 45-75 based on hwy and traffic...commute from MD into Northern VA.......through two lane state roads four lane interstate and toll roads over some rolling hills....and about 5-7 miles city driving with stop lights/signs |
