I have put 4,000km on my RX now and just got 8.8L/100km (26.7 US mpg) on a highway trip (300km) using the a/c and cruise control. Around town it is still giving me about 12L/100km (19.6 US mpg). I am using 91 octane PetroCanada (Sunoco) or Shell Gold fuel exclusively.

 

quite good FUEL your "91 octane PetroCanada (Sunoco) or Shell Gold fuel exclusively"
looks like a 98 in Europe...

 

I'm ave 15mpg on city driving with tons of stop and go.

 

mileage is 3,477. Average mpg now up to 20.0

 

Hey, we're almost the same, mine is @ 3661 (3 months old) with combined highway and city (from home to work with 18 stops one way), so far I'm averaging 18.1mpg despite my aggressive driving.

On pure city driving, I ave. around 17mpg.

 

I now have 6349 miles on my RX and have averaged 21.7 US mpg. The best mileage was on a recent 800 mile trip to New Brunswick where one tank averaged 26.6 US mpg. I would encourage all posters here to start using the Fuelly.com website to track their mileage. There are currently only 4 2011 RX's posting fuel usage there but it is an easy to use site which allows easy conversion so that those of us living in a metric environment can easily convert to US mileages and relate to those of you who live in the USA.

 

I've got just over 3000 miles on my RX450h, and the mileage over the whole time is 26.60. All numbers are actual measurements--I keep track of all gas. It started out lower at the beginning, in April, and has improved with warmer weather. My best tankfull has been 31.09, running at the beach. My best shorter run was a 100 mile round trip with two passengers, and I got 36.4.

I'm happy.

 

450h FWD ... averaging a little better than 30MPG with primarily in town driving.

 

Almost 9000 miles on my 2011 450h with a lot of stops and idling, average 18mpg. 22-26mpg if I am careful with the gas pedal, but will get a lot of horn blowing.

 

I agree, this is almost exactly what I am seeing on my 2010 RX 350.

 

I just completed a 46oo mile round trip between Tucson and Western Pennsylvania. I had just over 20000 miles on my 2010 RX350 at the start. I averaged 24.9 mpg for the trip with much of the time at 80 mph. I am totally satisfied with that kind of mileage for this type of vehicle.

this is my stats, i dont drive aggressive.
highway only: avg 10.2L/100Km which is: avg 23.06 MPG
mix highway60%/city 40%: 11.6L/100Km which is: avg 20.28 MPG

 

almost 3,600 miles and average mpg has moved up to 20.3

 

With over 50k miles, we're finally getting around 20 mpg. Use to get 18-19 average. We are not easy on the peddle though, and the eco light is rarely on. We take full advantage of our K & N filter and CAI. NOt bad for this peppy little 2+ton LUV.

 

5000 miles on the clock and we average about 15mpg in the city, and 24mpg highway. Should have gotten a hybrid or diesel.
