Here is a good source for gas mileage based on a large number of cars with many miles driven.

It's interesting to see that the newer cars get pretty well the same mileage as previous years.

Had mine for about 12 hours. 121 miles.

 

Wow you guys have bad traffic in the northeast.
Congrats!

 

I am new to this forum, but I would love to share my joy of owning a 4 gen Lexus RX F sport, this is been my dream car since 2015, and I pulled the trigger on this year, the car is great, my local dealer is even better. and finally today I accomplished 25.43 mpg and over 400 miles per tank's mission. this is local and highway combine miles. my wife was driving Infiniti Qx 30 with 26.2 mpg.
and heck yeah !!!its not the car, its how you drive it, be consecutive.
P.S. I found 89 octanes to be best for my car

 

How the heck... I get 17. But I'm always on sport+ and usually drive local only hahah

 

with MAX A/C and sport+, I got around 21, it really depends on you put your foot on the pedal, I cruising most the time,

 

 

CONGRATULATIONS. I have a 2019 RX 350 with 900 miles and averaging 19.5 miles per gallon. I too hope it will get better.

 

Hello Everyone!
I am a new Lexus Owner! 2017 Crimson Rx350. I do have a few questions if you don't mind or if you can point me in the right direction that would be great!
What kind of gas mileage can I expect hwy? Any known issues? I sincerely doubt this but do these cars have any issues with rattles in the car??
Thank you everybody!

 

There is already a thread about the subject. Lots of reading here! https://www.clublexus.com/forums/rx-...ge-thread.html

 

Thank you for that! I’m really surprised these cars don’t appear to get the advertised gas mileage. Is that a common theme?

 

I get between 19 and 21 on the highway but then again, who drives the speed limit? I'm sure if you go the speed limit on the highway, you'll get advertised rates. But if you're going 75 or 80+ mph, 19 to 21 is what you should expect.

 

2017 RX. Just drove from Savannah, Georgia to Ashland, Virginia, Pretty much kept the cruise at 77 on I95 the whole way. Got 26.4mpg. I'm pretty happy with that.

 

So this morning I got a fresh tank of gas and I remembered this thread. Drove 25 miles highway, 5 miles city. Got about 26 MPG. On my way back home, about 15 miles city, 15 miles highway, went down to 22.7ish.
