I get 29 on the freeway but only go 110 kph, 130 will use more.

Default Happy with MPGs

My wife's 2020 RX 350 recently got more than 30 MPG on a 450 mile R/T (mostly interstates). Highway mileage has been very good since new. City driving is probably in the neighborhood of 18 MPG in warmer weather; less in January!

Just picked up my 2021 RX 450h a week ago. Haven't refilled the tank yet, but the onboard computer says I'm getting a little over 30 in mostly city driving. We use ECO mode on both cars.

The 450 will be used for short trips on city streets as the MPG is much higher.

Cheers!

You both must be masochists!
The ECO is so unresponsive that I find in city driving it's a torture; On the hwys though it may work as you don't need the quick throttle response.

it's not about racing, but in ECO it feels you are beating a dead horse dragging a log behind.

Interesting you telling him how "he" feels. I'm guessing he is fine with the feeling and others must as well or it likely would not be an option!

Not surprising though. You are the one that tried to tell me I didn't understand how the rain sensor wipers worked even though I've driven Toyota's for over 20 years!

Funny how YOU interpret the way I feel while driving in ECO.
Keep on driving a Toyota for another 20 years and wallow in your ignorance.

That's right, we all drive with different styles, at a different pace and in different areas (hilly, flat, windy, etc)
Mines fine where I live, slow paced, flat.....she's as smooth as silk. But I use Sport Mode in the big city where it's go, go, go.......

Folks, please relax. Everyone's driving preferences are different and there are many factors on why that maybe the case.

Default Terrible MPG

I'm locked in for 46.

I've only bought used cars before. I was open with them about this being my first lease and I ended up being there on a Sunday night after looking for a car for about 30 days.
*********
I'm driving a new RX 350 AWD and getting HORRENDOUS gas mileage, just like your ES.
My previous Lexus was a 2017 ES 350h and I got 40 mpg city quite easily. I'm getting like
10mpg city in my 2020 RX 350 AWD and can barely get around 17 mpg Highway if I REALLY
GO EASY. Pretty upset with this as I'm getting roughly HALF of the estimated EPA MPG.
I knew the mpg would be bad for the RX, but it should be close to what they say it will get!
I'd be buying HALF the gas I'm buying now!

MPG TIPS:
And for everyone, HOW you drive makes a huge difference. The main thing is starting off from a stop gently,
and don't use the gas pedal to fly up to red lights. Coast a bit if it's not blocking someone behind you. Idling
absolutely destroys your MPG, and that's precisely why Hybrids are SO great in the city. Instead of idling
the gas engine, that's when they switch to battery power, saving you tons of gas. If you accelerate gently
stops in your hybrid, it will take off on electric power at first, also saving you a lot of gas overall.

On the Highway I get around 27 MPG. Went to Toronto a week ago and averaged 26.5. Almost all at 115-120 Kph...not too much wind either direction.

I thought with the 8 speed it would be better...24 city 30 highway. The old 3RX always got over 30 on the highway.

I still do MPG as I have for 40 years. Kilometers per litre or litres per 100 kilometers is greek to me!
Yeah I too am disappointed with my 2017’s fuel economy. My 2nd gen was no worse and often slightly better with only a 5 speed. I fail to see the progress here.

Default RX - Fuel

Leveraging off the MDX versus RX thread, what fuel do you put in your RX, and what gas mileage do you get. I'm on my 3rd RX, (2004, 2013, and 2021), I've always put in regular (87 Octane). Anyone use 88?

Always regular - MPG? Who knows - I don't pay attention but the computer generally says low 20s.

Regular (but only top tier gasoline from Chevron or Shell)

Getting 13L/100kms = 18 MPG in the city

"Top Tier" gasoline appears to be the best choice to keep your engine clean. Here is where to get it: https://www.toptiergas.com/licensed-brands/
All gasoline grades at these locations must be treated with an approved detergent at the correct concentration. These are very high standards established by the TOP TIER Program.

All is not lost if you have been buying cheap gas. Get some Chevron "Techron" Complete Fuel System Cleaner from Walmart and put that in your tank every 6000 miles or 6 months.
Always use the recommended octane rating of the manufacturer.
Getting about 16 mpg here in the city.
