After 17 months.. 32mpg and dropping
Overall average since driving off the lot, never reset: 35mpg
Current average: 32.. Seems to be dropping
Running tires at the recommended factory psi, check them with TPMS regularly. Only drive the car a couple days a week. Mixed trips, sometimes a 100 mile round trip commute into the city with hilly terrain on the 15 freeway in Southern California, other times just a quick couple mile trip to the grocery store and back.
Always run the car in ECO mode. I do sometimes have a lead foot if someone agitates me or I'm in a grumpy mood lol, but most of the time I just gently press the pedal when the light turns green.
Highway driving: Speed limit here is 70, usually run around 75-80 with the rest of the traffic on the freeway (we like it fast in SoCal!). I'm sure it would get better MPG if I just drove it 70, but when you're driving 100 miles round trip the 10mph gives you an extra 15 minutes of time back.
Not sure why this car is so inconsistent from the EPA MPG, our Prius consistently gets 51MPG on each fill up. No matter how soft or hard I drive it,.. But it's a Prius and not as comfy as the Lexus.

Occasionally, I've noticed that my FE will drop as I'm waiting at a stop light as the engine continues to run even though the engine is already warmed up and the battery at 3 bars +. So trying to figure out why the engine is still running, I press the EV button, but the dash says this mode is not available.
I turn off the vent fan and the engine stops. I turn on the vent fan and the engine kicks back on. This happens occasionally but not all the time. The weather here has ranged between 40 -60 degrees with only the vent fan. I guess the fan and possibly any other electrical draw may keep the engine running and effects the FE. Must be the computer algorithm?
Not to complain but I'm currently getting between 35-38 mpg during the winter which is a little less than 37-40 mpg in the summer even with AC. Or it could just be me

I just realized I haven't said anything about gas mileage, yet. ..
I didn't buy my es300h for fuel mileage. I have a long commute, but there is an HOV lane on that highway. So, I actually bought an HOV-lane sticker. It just came with a car attached. My previous car was a Camry hybrid, bought for the same reason. I decided to buy the new car because the Camry just wore out -- beginning to want lots of small repairs.
Before the Camry, my previous car was a Tundra with a V8 motor. It got something like 14 mpg. I played with hyper-mileing for the first couple years with the Camry, but in the traffic around here I never got much better than 38 mpg. When I stopped worrying about it, and just continued to drive gently, I got about 35 mpg. I figured, 3mpg isn't worth a lot of trouble. Moving from a 12mpg Tundra to a 35-ish mpg Camry cut my fuel bill by two thirds. Going from 35 to 38 would not make much difference.
So far, this es is getting just about the same 36-ish mpg. That includes driving 74 (indicated) on the highway when I can, and keeping up with traffic the rest of the time, for a 50-mile-per-day commute in a major urban area. (Around here, they don't stop people for going 74, paying attention, and staying middle of the lane with some following distance. There are plenty of fools going 85 or 90, weaving across three lanes while texting and/or drunk, and hitting other cars in the process, to keep the cops busy.)
One detail I like is, when traffic congests for a collision, I can remain stopped or idle at 5-10 mph without running the gas motor very much. The great advantage of a hybrid is not at highway speed. The great advantage is in stop-and-go traffic. I can actually hear my stereo, without all the noise (except, of course, from the other cars).

THIS!
the 5-10 min I save commuting daily more than make up the premium over the es350 model.

.What seriously annoys me is cold air coming out of the vents even with temperatures set to 24C (Normal mode, not Eco). Sometimes the AC runs to dehumidify the cabin and it's a nasty surprise to get a cold breeze when it's freezing outside.

Here is a good article from a Prius chat room:
Due to the Prius' typically high baseline mpg figure, the mileage drops may seem worse than they really are. To quote from Car and Driver: Mileage? No, it's Your Gallonage that Really Counts
There's a sneaky illusion in mpg numbers. Consider: If your pickup rated at 10 mpg gets only 9, you shrug and say it's off only 1 mpg. But if you drive a hybrid labeled 50 mpg and it drops the same 10 percent to 45, you complain of lousy mileage.
The illusion tricks you once again when you think of mpg instead of the fuel you actually burn. Hybrids are chosen by people who think saving gas is right up there on the list of American virtues with motherhood and voting. But when the hybrid gets 45 mpg instead of the expected 50, a 100-mile trip consumes less than a quarter of a gallon more than expected. Compare that with the pickup that gets 9 mpg instead of 10; its 100-mile trip burns 1.1 extra gallons.
The loss of 10 percent on the pickup's mileage actually burns five times the extra gas used by the 10-percent shortfall in the hybrid...
Here are some sample calculations to illustrate the above:
100 miles / 50 mpg = 2 gallons used
100 miles / 45 mpg = 2.22 gallons used
100 miles / 20 mpg = 5 gallons used
100 miles / 18 mpg = 5.56 gallons used
So, if you had a 20 mpg vehicle that dropped to 18 mpg, you might not even notice it or dismiss it as noise. Yet, the 2 mpg drop in that vehicle actually caused ~2.5x more consumption.

And that's why I've got my fuel consumption shown in liters / 100 km 
It's easy to compare a percentage delta and a total volume delta between cars. For non-metric users there's nothing outside mpg... No gpm?

@djrobsd, I'm at around 35.9 average with a total of 15K miles in one year of owning the car. Previous tank I was getting 38.9 mpg and then this tank I'm at 37.
Very inconsistent.

I wouldn't consider that inconsistent. All it takes is a change in weather or driving conditions to get a couple of miles per gallon change. In fact when we went from 70s to 30s in December mine varied a lot more than less than 2 mpg which you are experiencing.

I never use km/L and neither does any other Canadian I know. Interesting that Lexus has a readout in that measurement though.

Currently getting 39-42 mpg actual calculated mileage, and essentially always in sport mode and 60% highway..
Even at today's gas prices, lovin' it. It's only when, not if oil/gas prices go back up.

It gets 36 mpg, on average. Slightly better on surface streets. Slightly worse at uncongested highway speed. But a lot of my driving is on heavily congested highway.

300H gas mileage
I am in Florida and now have 30K miles on my 2013 300H. Run it in Normal mode and have not reset my average MPG readout setting in about 6K miles and it shows an average of 43.1 mpg. I find by not resetting the average miles per gallon readout I am less preoccupied with tank to tank variation. Can always go and look at the "since last refill" readout to see variations
