When I am going to the office more often, and not working from the home office, I am between 30 and 31 mpg. Otherwise, like now, I am right around 29 mpg. That "about" 29 mpg is mostly local driving with me "enjoying" the car more often than not.

When I had the original Kumhos on my Dart I averaged 32-33 each week. When I replaced them with a set of Yokohamas it dropped to 30-31 avg. Now with the tires badly worn I'm only getting 29-30. Decent tires and correct air pressure make a world of difference with gas mileage.

My '13 2 litre manual averaged 33+ for the year I had it. I was quite happy with that. My '13 Turbo read 20 average in the sales lot. Judging by that I think its safe to say they had regular in it. Since switching to premium and driving it for a month-ish now, the average meter is bouncing around 28.
Its been a few months now, still averaging 28 ish with the Turbo. It could probably go up since I've taught myself how to lay off the boost to get better mileage. But the times I don't drive eco are bringing it down some.

So for me at this point, it's really the idea of driving slower.. Unfortunately..

With my GT, I have found that it roughly goes like this: (Realtime at speed/not average)
40mph - 50mpg
55mph - 38mpg
70mph - 33/34mpg
90mph - 28mpg
Moar ph!!! - 22/24mpg
Gun it!!! - 4/8mpg

When there are hills, laying off the gas a little on the incline and then being quick to get back up to speed at the top, then letting it coast on the decline seems to fair better for gas milage.
Cruise control does help A LOT, but I can do better without it if I am actively 'hypermiling' it.
Also if I floor it.. 24mpg. That was my average for a little while. Could probably get worse if I really tried but I would have to drive pretty stupid.

My current average is 31mpg.

Yeah therein lies the problem with the 1.4; the engine alone isn't strong enough to actually keep up with traffic, so I'm constantly over 3k rpms running boost and my mpg drops like an anvil. Typically for the best mpg, you want to be in the highest gear with the lowest rpm. Top Gear did this once with an economy car vs a powerful car and the more powerful car got better mpg because it didn't have to work as hard to keep up with the economy car.

Is that what happens when you fart inside a sealed cabin? :eek:
So that's what happened! It's a sealed up VW Bug that someone blew a smiley in! ;D

To that, I have often wondered if that concept could be real or not.. Makes me wonder now if I should have tried to find an SXT Challenger. Only between 2 to 4 MPG less than the Dart.. (2019s are rated for 30mpg)

That reminds me of the scene in Demolition Man where Sly Stallone crashes his car and ends up encapsulated in safety foam. We're headed in that direction, folks.

Getting back on subject, yes it's true that a lot of mid-sized and performance cars actually meet or beat compacts for mpg. Compacts exist because they're cheap, not because they're the most efficient cars on the road.

Dirty oil resulted in a loss of 10mpg on my Dart. Never thought it would make that big of a difference.
I guess it makes sense due to Multiair though.. It did seem like I got better MPGs after I got an oil change last time but didn't think it to be anything more than placebo. I feel like that may be a different scenario on the 2.0L.

A little while back the wife and I drove north from the Tri Cities to Spokane. 135 miles with an increase in elevation of 1400'. Going up we got 34 mpg and coming back we got 38 mpg. I haven't checked city mpg but we don't drive much around town.
