in the city: yes
on the highway: no

My LS gets 27-28mpg going 77-80mph on the interstate between Tucson and Phoenix, chevron 91 octane gas, Bridgestone Turanza tires at 35psi. Since my LX and LS have virtually the same engine (4.3L 3UZ vs. 4.7L 2UZ, LS revs a few hundred rpm less due to 6spd tranny), on a flat highway, the major difference is wind resistance (plus some to the full-time 4wd on the LX drivetrain). That's what makes the difference between 16mpg and 28mpg going 75mph, nearly a factor of two!

Some typical numbers I got on various cars I've owned:

-1986 Toyota 4Runner 4x4 with 2" lift, modified exhaust: 19-20mph going 70mph on the highway
-2001 Honda prelude SH: 26-28mpg, city and highway, chevron 91, all stock
-2000 Honda CRV 2wd: 26mpg both city/highway, chevron 87, stock (no change w/ higher octane)
-2003 LX470: 15.5/17.5 mpg city/hwy (70mph), chevron 91, aftermarket bumpers
-2005 LS ultra: 22/32 (hwy 70mph)

This gets better gas mileage. Well.....considering it's hard to drive civilized maybe not at times?

The LS is my highest MPG vehicle -- overall average reads 21.9 right now, and it hasn't been reset in thousands of miles so that's a pretty accurate number.

The GX averages about 17.5 in overall driving (this is actual calculated MPG -- the GX computers are about 1.5 MPG optimistic vs. actual, so the computer says about 19, but it's wrong).

I don't know the average MPG for the Supra but it burns up to 1.2 gallons/minute at full boost, so it's not good most of the time. Factor in the price of race gas (~$9 for what I usually burn) and the LS and GX start looking downright frugal, fuel-cost wise. I don't know what that says about my psychographics, though.

Did not keep up with this thread after a while I guess. Anyway, this is not a logical deduction of the results from the answers and poll. The LS although not a gaz guzzler like an SUV, is also not a fuel efficient vehicle in the sense of it being as good as a compact, say a Civic or Sentra. In my case, the LS is my most recent vehicle, and MPG did not factor into my decision at all. Yes, I have my Integra already and not many vehicles will beat that in MPG, but even if I had just my RX, I would have gotten the LS anyway. I think if an LS is in someone's household, unless the complimentary vehicle is a big SUV, the LS will not be the most fuel efficient.

So, let's put it out there, who was concerned about MPG when they decided on their LS?

True. I wrote a paragraph on how waaaay too much was being read into the answers to the poll, but just deleted it and posted what I posted only.

There are typically no simple answers to the MPG question.

I personally was very concerned about mpg on the LS to the extent that I would not have bought the LS if its overall mpg was below 18 mpg.

This was not a gas money consideration, but a moral/ethical concern to not drive what we consider gas guzzler cars. To us the gas guzzler line is below 18mpg. Everyone has their own judgment on that line. That's my own bias and prejudice - the people that drive around in the Hummers are douche bags as far as I am concerned. But some group of people see me in my big heavy LS and likely think the same.

Another factor in our consideration is that both of our cars only get driven 6-8k per year max. The other car is a 06 highlander and gets great mpg.

If I was commuting or using a car for work running 100-160 miles a week, I'd likely buy a car that averaged mid to high 20s mpg.

At the same time I won't buy a tiny light super high mpg car under any circumstances because I feel small light cars are too dangerous to the occupants in a crash. This feeling is heightened by where we live given the huge number of drooling idiots driving the the DFW area streets and highways.

The "your vehicle gets too few MPG and therefore you should be ashamed of yourself" is a narrow-minded, holier-than-thou attitude, ESPECIALLY if the accuser doesn't take into consideration how many miles the owner drives. I arranged to live, work, and school my kids in a 3 mile mile loop. So, I can drive 6 miles a day for 2 adults to go to work, two kids to school, and stop at my favorite grocery store if needed. My big, earth-murdering daily-driver 17.5 MPG SUV burns 1.7 gallons of fuel per week for this purpose. The self-righteous ***** with his Prius getting 45 MPG, driving 50 miles per day to work, and burning 5.6 gallons of fuel while badmouthing SUV's and SUV owners can suck it. I say he should be ashamed of himself for his inconsiderate choice to live so far from work.

i just drove 100 mph (had cruise set at 101, cuz it wouldn't do 100 even, either 99 or 101 for some reason) for 15 mins straight on the highway keeping pace with a couple other cars that had the lead so i figured i would see brake lights if there was any reason to slow down; any who i was averaging 21 mpg on the flat roads while going 100 mph for about 15 mins straight... i find that pretty damn good if you ask me. hit 120 a couple times for a couple mins and averaged 70 mph on a 1 hour highway trip getting 23.5 mpg by the end of the trip. this seems pretty good to me, what do you all think¿¿¿ btw i had just filled up about 3 blocks from the highway entrance and had reset all the counters after filling up.

my wifes car gets 38 mpg,, when you drive it properly

I guess I would have expected a little higher than 23.5 average if you were averaging 21 at 100 MPH. Mine does about 27+ MPG at 70 MPH, but I can't recall what it does at about 45-50.

well maybe i explained it wrong... i had reset all the counters prior to jumping on the highway and then i was going 120 for a couple mins, 100 for at leasat 15 mins straight and when i got to my destination my average speed said 70, which included exiting the highway and driving about 5 miles on normal stop and go city streets... and at the destination after stopping it was at 23.5 mpg average.

if i just get on the highway and set it at 70 yeah it will def get better than 23,,, not a bad highway cruising car i must say.
