I have the pzev with the 5spd. When I'm driving REALLY conservatively (shifting around 2000 rpm, driving between 50-60mph highway, keeping plenty of coasting distance between other drivers and myself to minimize stop and go), I've been able to hit 40 mpg more than once. When I'm driving aggresively, I get around 33-34 regularly. About 3/4 of my 18 mile one-way commute is highway and most days I'm able to maintain 55-70 mph.

44 to 20? That's a crazy swing!

But for a relative short test, flat ground with the cruise control is best, just for seeing if your car is performing correct.

This is the same experience we have with our 2014 CVT PZEV, is yours also a CVT PZEV? Seems like the folks with this particular combination of CVT+PZEV are struggling to achieve any MPG numbers near the EPA ratings.

No, mine's not PZEV. I can hit, and exceed the EPA numbers, BUT, it absolutely won't happen if the engine is cold. The EPA tests are done on a fully warmed up system.

Once the engine is warm I can easily exceed the EPA estimates. Once everything is fully up to operating temperature (diffs, etc.) I gain another 1-2 mpg. UNTIL that happens though, holy %$# does it guzzle gas. And even with trips of 20-30 minutes, you're still spending 5-15 minutes in 8-12mpg range, so your average will suck.

All models after MY12 are PZEV. Have you tried the method I posted above to find out if your car can meet or come close to the EPA highway estimate?

My mpg average has risen to over 27 since it got warm, all city milage and I drive like a d*ckhead. My one full road trip tank netted 32 mpgs, in the mountains of PA @70+mph with a few construction delays and spurts of rush hour traffic.

Earlier this year when the temperature was in the 20's some mornings, it took over 10 minutes of driving for the coolant to reach normal operating temp (196 degrees.)

As far as the CVT fluid, 13 quarts is a lot of fluid to get hot and I have no idea how effective the CVTF cooler/warmer is but it's better than nothing. My 5.0 AWD '99 Explorer also holds 13+ quarts of ATF.

I'm getting 25mpg city, 40-50mph stop and go, with a mostly hilly commute. Can't complain and I'm sure it'd be closer to the advertised 27mpg if the terrain were flat.

Only been on the highway once with the car for extended length doing 80mph the whole way and I only average 28mpg. I figure if it were a flat highway and I went closer to 70mph I could get much better highway mileage.

Mine is about 23/27. However I drive pretty aggressively with cvt. rpms between 2500 and 4k.

Got 43mpg highway today with a very slight (100 feet over 25 miles. yeah that's slight) overall decline and many small, gradual hills. Tried to take a pic of the (calibrated) mpg display but turns out my phone doesn't know how to take pictures without blurring them anymore.

Isn't that better than the prius?

55-60 no cruise because base model. Everything was off so the alternator wasn't adding any unnecessary load. It even stayed up there driving through the city hitting 2 lights within the mile I was on the road.

In our case, the car doesn't reach EPA estimates, whether it is warmed up or not makes no difference. Since 12/30/2013, we have exceeded 30mpg only once, and it was on a tank which was nearly 100% highway miles. That tank's MPG was 31.2 (hand-calculated). The highway miles were along a fairly flat stretch of I5, and never exceeding 70mph.

We've had 2 dealers examine the car, and each has stated that the vehicle is working as designed, and they are stating that they have not found any issues.

Consider yourself to be one of the lucky ones, not having PZEV combined with the CVT, the deadly combo!

I just got a record high fuel interval avg mpg of 34.44 (calculated), at about 44,000 miles. My last highest was 33.96 at 3,400 miles. My record low was 23.61 last November, due to 80mph Interstate driving with high winds.

Has it ever been suggested before to check the green diagnostic plug under the passenger dash? I was cleaning yesterday, saw it unplugged, and plugged it in. After some Googles I think you only connect it to put it in diagnostic mode. While it's in diagnostic mode it won't ever go into closed loop operation, aka bad mpg.

Random thought of the day. I unplugged mine again.
