Elliot, I always stop on the 3rd click off of the pump, and I usually go to the same gas station.

That is typically what I do. But as I discovered, there is more room in the tank after that. (I always was filling on empty and v and found I was always putting in around 16 gallons on a 17 gallon on tank. I also noticed I was unable to hit 700 mile tanks and based on my average FE, I should have (anything over 41 mpg with 17 gallons of gas should yield a 700+ mile tank - I was falling short every tank and exceeding over 41mpg on every tank ) . So I figured it was either not truly empty or not being filled all the way. After force filling the tank a couple of times, I realized the tank was not really full.

Does the 300 have the same issue as the 350, where the miles left reads 0, when there's still 2 gallons in the tank?

I heard topping off the tank after the pump clicks off is bad. That basically the tank needs a little "breathing room". Is this just a myth? Or are our hybrids different?

True, you can cause raw fuel to enter the evaporative control system. From the manual:
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.

I did a mileage check while taking a 200 mile drive and found that I was losing one mile on my odometer/display for every 50 that I traveled. I just happened to be going in for a service at my Lexus dealer and told the rep about this. He told me that it has to do with the condition of your tires. Newer tires will show less miles traveled and older, worn tires will show more miles traveled than what shows on your odometer/display. Since my tires are new (of course), I always add on another mile for every 50 that I travel when estimating mileage, at least for now. It made a difference in my mileage calculations. I will re-check as I get more miles on my tires.

I don't use the click to manually calculate MPG. I use my receipt and always reset my trip meter to zero at the pump.

Your receipt tells you exactly how much gas you put in. Your trip meter tells you how many miles you traveled consuming that amount of gas.

Seems like pretty accurate methodology.

"Seems like pretty accurate methodology." Yes it does, IF you were filling the fuel tank to the exact same level each time. Which is unlikely.

We have had our 2013 Leuxs ES 300H since mid Oct 2012, we are finding that the stated 40 city and 39 highway mileage is not achievable! After driving 11 K miles our overall AVERAGE is aprox 32 to 35 miles, we have recently voiced our concerns to the dealer. We are wondering what other drivers are getting in their numbers? Anxiously awaiting what others are getting, thanks.

I am getting 40.5. Higher when not driving over 75 on interstate. With the right combo of non interstate but still 55 moh highway and some 35-45 mph side streets I have gotten as high as 45. Read other posts about how to get higher mph. Have not needed AC yet either.

Consistently 42-44 in small town/4 lane mixed driving. For comparison, the '10 Prius we had got 55 over a 3 1/2 year ownership. It's driving style and understanding how to get the most from a hybrid.

I have had my 2013 ES300h since the beginning of January and I am averaging between 36 and 37 calculated MPG, the car states I am getting an average of 38.5 MPG. I believe this is great mileage for a car this size, better than the HS250h I had for 3 years and this is larger and more powerful. I do not try hard to get good mileage but always coast when I see a red light ahead. I mostly stay in ECO mode but do use Sport once in a while. No highway driving yet. 70% stop and go and the rest at 45 to 50 MPH.

I have had my 300h since mid-February. My average up until about mid April was around 36. Since that time, I have changed to sport mode specifically and I'm averaging around 39. I'm wondering if the change in gas formulations has something to do with this as well. I don't know when the refineries start to make adjustments with the changing temperatures. I live in Seattle.

Anyway, whatever the reason, I am very pleased!

Had my ES300h for 4.5 months, 3200 miles (mostly local suburban, usually no passengers, empty trunk, normal mode). Latest fill-up today netted 32 MPG (manually calculated), which is consistent with previous couple of tanks. Engine is broken in, cold weather is over, and I have been using the usual hybrid driving techniques. Why am I still getting nowhere near 40?

chardo,

Try driving in sport mode, getting up to 30-35 mph quickly and stepping off the gas. That will usually cause the car to go into ev mode and then you can cruise at that speed mostly in ev mode by staying light on the accelerator. I've been doing that for the last several tanks and have been getting my best mileage driving that way in the city. I have also used sport mode on the highway and it gets me as good or better mileage than eco or normal. Best Highway speed I have found is 70 mph.
