Just clocked this (and not all highway either) on my current tank of gas. The car spent several days at the dealer (who likes to leave cars idling / take them for joy rides as I've seen my tank average drop 3.0 mile/gal after a stay), and has had about 10-20% city driving. The strange thing, my avg mi/gal for this tank says 32.0, but 439/17=25.82?

I think that's pretty good. I snapped this right before I filled up this morning.
Did the 08+ come with a larger tank? I just filled up at ~14.5 gal.

The spec sheets state that all the 2nd gen IS250's came with a 17.1 gal tank

I guess I'll get back with the final algebra when I stop to fill her up on the way home this afternoon.

It is a 17.1. The "RANGE APPROXIMATE" reads 0 when there is 2.5 gallons of gas left in the tank. So technically, you can get another 50+ miles out of your tank

i hate you guys and your good gas mileage -.-

and ya he is right, it is only calculating 439/14.5=30.27 and its only approximate. if you were to drive another 45 miles(safely) then fill up. then youll see exactly how much gas you used and how far you went. ive gotten over 30mpg 3 times when i had my 350 actual with a calculator. but that was with cruise set at 70 in socal your holding up traffic with 70 lol

I'm not sure on this, it might be in the manual, but is there a limit to when the Tank Average or Miles Remaining resets? Maybe they topped you off with 2 gallons before they gave it back? maybe 2 gallons isn't enough to reset everything?

just guessing here, because I've never put less than ~10 gallons in at a time.

I wouldn't think 439 is too extraordinary though...the best I've gotten on my 350 is ~410

Thanks guys, didn't realize that.

AP- just did my math and came out to 27mpg for me, but screen said tank avg was 29.4...

That's stupid. I want to know how long I have until my car is stalled on the side of the road. They already put in an idiot light to tell you to fill up the car at the next convenience.

That's nuts. Most I have got on my IS250 is about 340. Mostly city driving with some hwy. I hate to put miles on my car so I stay away from long trips. Under 3,000 miles still!

Yeah the whole reserve tank BS is for those goofy people who are probably a little dumb to get gas in a timely manner

I also wouldn't go by the little screen's average, I STILL use the trip setter every time I drive as I find it to be more accurate.

LOL @ idiot light. That mpg is much better than mine.

im only getting 18 for city and highway each.

only city driving mostly and highway sometimes on weekends.

I do all city driving and I get 16mpg if i'm lucky...last I checked was about 260 miles a tank...horrible.

I got 440-450miles once on a round trip Houston to Corpus once. It was cold out, and i babied the hell out of it just to see how good the gas mileage could get. Made it from the gas station at my neighborhood to Corpus and all the way back to my gas station and the Range Approx hit 0. Great timing

Best i ever got was on a road trip up and down Cali. Got 485 miles on a tank with 17 miles left. I really wanted to make it go to 500 miles so i could take a picture but didn't wanna risk running low on gas through the grapevine lol. I try to never run the car past 0, I believe someone on here explained before that its not good for the fuel pump at all (overheating) when you get down to having only a little amount of gas left.

Right now im commuting to work everyday, mostly highway and averaging 30-33 tank MPG. Freicken love this car! Looks good and gets awesome gas mileage Average MPG is at 29.0 right now, i think the last time i reset it was about 17k miles ago too!
