The reason I am asking this is because I am going to purchase an LS460(in 2-5 months) when I sell my IS350, and I want to know what LS460(either one) owners are averaging out of their daily commute. I will be driving about 30% in the city and 70% on the freeway.

 

stock - 22mpg
now (22s) - 21mpg (dropped a bit)

maybe 40 local and 60 highway

 

Here in the frozen Midwest, I have been averaging about 17mpg the past 10 days and 25 on the Interstate. The reason I am mentioning "frozen" is because gas mileage goes down substantially in very cold weather. It has been sub-zero at times along with snow. A couple weeks ago, when it was not so cold, I was averaging about 19 in the city and 26-27 on the highway. Wind also is a big factor. It can help the gas mileage or hurt it a lot. I am pretty certain, that by March and April when the high temperatures reach at least into the 40s, 50s, and 60s, my gas mileage will improve by at least 2-3 mpg.

 

22.8km/100L

 

I average 17 in the city (hills of Pittsburgh) and just got back from a 24.5 MPG highway trip thru flat Ohio to Detroit.

 

I avarage 14 - 15 in the city and 27 - 29 on the highway.

 

18.5 mpg. Not much freeway driving.

 

mine is 11.5 Liter/100KM.. 70% of the time i'm on high way , 30% in city

 

22.1 in mixed driving over 12,000 miles! I also live in the Pittsburgh area where we have a lot of hills. I am very pleased!

 

14.8 mpg....lots of stop and go, short runs.

 

Here is what my mpg has been since the car was new (07 LS460). The paste did not line up exactly, but average=18.37 overall for 7,658 miles on premium grade fuel. the trips on highway are over 20mpg.

7,658miles/416.828gal = 18.37mpg

 

Gas mileage for my 460SWB is remarkably good (better than my old BMW 540 which was smaller and lighter).
Here in Wisconsin in the city I get at best 18MPG (warm weather, no AC). My worst in city is right now (0-ish temps & mucho snow), abt 16MPG.
On the highway MPG is great, over 29 in warm weather and steady 70 MPH.

 

wow and i thought i had bad MPG on my sc :]
then again.. i do have bad mpg :'(

i always thought the LS460+ had great MPG

 

i don't know about your sc, but the ls460l has been far superior to our gs400, is300, or the sc430 in terms of gas mileage

 

Mine is 16 in the city and about 26 to 28 on Highway depending on the wind how straight and flat the highway is like the Kansas I70 East to West.
