Well, it answers one question anyway - one of ours (at least) is not behaving normally, unless they changed from '12 to '13. Hopefully others here (with a CVT) can give us some more data points here.

It is not until I give it some gas or the engine speed slows to basically idle in the gear, which is the same thing, that it goes back to drive. When depressing the gas pedal, it will go back to drive under any conditions after only a couple of seconds (even when downshifting and then upshifting).

Is that not how everyone's works?
Mine stays in gear going downhill until I do something to make it go back to D even if it holds a steady speed. But then we don't have very big hills around here. I usually use a paddle up to 6th to defeat the D mode downhill engine braking.

I really hated the engine braking at first but have gotten used to it. It makes sense for maintaining a set speed without having to stab the brakes as often.

Eco driving 101, if you have to use the brakes, you lose.

Yeah, I am used to it - a lot of cars now downshift when going down hills to increase engine braking. After having driven a few hybrids I wish all cars would take back energy from going down hill. It wastes a lot of fuel in the mountains.

The only time I've come across where it auto-resets to D in less than about half a minute of "shifting" is when I reach a full stop.

Not sure if that answers your question...?
Only as a data point: Mine acts the same as described above.

Interesting - Correct me if I'm wrong, but that's three of six that work each way - three (Webster, Lympho, and Guzzi) hold while giving it gas going uphill for "half a minute(?) or so", and three (hemo, John 451, and me) go back immediately to drive. When going downhill and compression braking, the first three will go to D when the speed stabilizes, three will hold in the paddled gear.

What's up with that?

Filled up today... 358.1 / 12.502 = 28.64mpg AVG speed was 36mph. Another dissapointing tank. Car never went above 4k rpm, or above 70mph, no hard accel, super boring driving bye the way, and as usual same commute. It is higher than this.. but for discussion sake, 75% highway - One would think that the MPG should be higher than this, I do!!!

Lol at least mine doesnt burn oil AND get crappy mpg's...
My driving is 75% around town, not a super busy city, but a town of around 50-60k people... my average mph is waaay lower than yours and with my 5mt and not totally driving like a church lady, I easily get 32-33 average mpg.... one good aspect of the car

It is really amazing at how much just a little city driving will drop your mpg. It isn't linear, ie 50/50 split = epa combined.

In my last car even 20% city and I would be just above city estimated mpg.

Lead feet are bad for mpg. Pretty sure you'll never learn cuz learning is, you know, boring...

What you're doing on the highway is probably more important than just the amount of time spent there. Are you able to get into the fast lane and just cruise, or are you constantly slowing down and speeding up due to traffic.

I drive faster on the highway so I can sit in the left lane, and I pay for it with the mileage going down, but if I drove slower, I'd spend more time adjusting my speed and probably do worse MPG-wise. If you want super awesome highway MPG, set the cruise for 5 under and sit in the right lane...but ain't nobody got time for that.

Amazing how people with an MT will not only monitor but post advice on a CVT thread...

Last 3 tank were 30.1, 31.5 and 32.4 mpg. Once the winter tires come off and summer gas back in thetank i see no problem with beating the epa numbers.

Really, another tool, Why would you post that.. I am being honest and sharing my data... I have never, repeat never driven this car like a performance car or with a lead foot since new you clown. You have obviously not read any of my posts on how I have been trying to achieve the highest MPG's I can from this car. Just DONT

Agreed! Finally, maybe you all will understand, this is what I have been dealing with and complaining about. And this is not city like driving around in Manhatten, city.

I was doing better with my other cars on same test sample. The only variable that changed was the car. It is beyond frustrating. Not just here to complain, but there is a problem, just want to find if out if others are experiencing same and to find a resolution. Bought car b/c based upon MPG claims felt was going to improve overall situation. Def finding out the hard way, this is not the case. Some of you may not understand or believe, but it is real.

At what RPM are you accelerating? If it's close to, or above 3K, don't expect good mileage.

It is very smooth and when cold right near 2800 to 3000, once car is warm the RPM's drop significantly.

With the CVT, less than 20% are getting the combined mpg (30 mpg), but over half of the MT's do (28 mpg).

I know it is real. I have another car, also EPA highway rated at 36 mpg, and it gets 8 to 10 mpg better mpg than the CVT on my commute which is over 90% highway.

You said 36mph avg, that's the issue right there. When my avg hovers just above 30 my combined is ~28, when I get closer to 50 it's more like 33. It really doesn't take much stop 'n go to kill a tanks avg.

Also look at the list for the Crosstrek. We are averaging lower but there are a few standouts (like mine ) although there are only two or three of us getting the epa # or above.

Overall though I do have to say that I didn't expect more than the 27.4 I'm averaging so far but it will be nice to watch it go up just a bit with summer gas and warmer temperatures.

My feeling is that they all behave the same. There's probably several variables in play (such as incline, speed, rpm..etc) to determine when it switches back to D.

Side note, I turned off auto climate control today and it seems to improve my fuel economy by ~9%. More testing to come.

I noticed something yesterday coming home from work. My original statement holds true as long as there seems to be some kind of load on the vehicle, such as engine braking or acceleration. If I perform the same test on fairly flat road, it goes back to D almost immediately.

Steve, your corolla seems to be an exceptionally good one. I had a quick look on fuelly and on avg it seems to be getting approx 30 mpg. Again, just a quick look no calculation.

What year is yours?

It's an '04 5-speed, Michelin Energy Savers at +3 psi. It's had Amsoil SS and tufoil in the engine and xmission for almost 200,000 miles - plus my commute is freeway at an average elevation of around 6,500 feet so not as much wind resistance. It's also had a K&N AF for most of that. I just changed the oil after 24,000 miles but before I did I sent in a sample. It's starting to use oil - about a quart every 5-7,000 miles and it was a quart low so I figured I might as well change it. The oil sample came back as "satisfactory for continued use".

I think the 5-speeds get better mpg there too compared to what is posted as the EPA highway figure. How does one download the database for a model? It would be interesting to see the difference between the 5-speed and the automatic. Fuelly shows a double hump (at least) curve for that year, the two major peaks are at 29 and 32, with minor peaks up higher than that - I'll bet the major peaks are auto and 5-speed though.

I have a sport limited crv. If I drive 55 with cruise control and no one else in the car, I get 37 mpg. Add adults, cargo, drive faster, etc and it plummets.
