2023 8speed auto/. 70mph=1900rpm. 75mph=2100rpm. @arentz07 was right on.

How high would the price of premium have to get before you guys might drive the IS500 less? I currently pay $4.75 per gal here in Hawaii, guess it would start to hurt a little around $7 or more.

I will reduce my food consumption before I let MPG dictate my vehicle choice or driving habits lol

Premium gas in my area is currently somewhere around $3.99. Honestly, I'd probably do like @AkioToyoda4Ever and eat out less or something like that. Ramen is cheaper and probably less-bad for my health than fast food.

But seriously, if it cracked $6 I'd probably start getting anxious.

i thought I was reading mpg on the dash but it doesn’t tell you, it’s MPH average!!!!
I get 22mpg by manual calculation of miles when filling up. Wish it said mpg on the dash

There should be an option for average mpg too. Mine show 28 + range for the 1st 2000 miles.

You can look at the Trip Information in the infotainment screen. Also, you can display it in the gauge cluster. If you go to the Settings menu on the far right, you can change what is displayed in the gauges.
