Everything I have driven so far:
 
68,066 miles divided by 2,722.9 gallons = 25.0 miles per gallon

Since there are not many 2009 4 cyl HL owners out there right now, I thought I would start posting our MPG. Our 1st tank went for 22.44 MPG in mostly in-town driving. Our 2nd tank went for 23.32 MPG, and that included about 100 miles of highway. Overall, we're getting close to or better MPG than the 2004 CR-V this replaced. I'm hoping it improves a bit as the engine breaks in, but overall we're really pleased, especially for the size of the car.

For an accurate mpg read, I wouldn't go by the computer as they are more of an estimate.
 
Do the math of # of miles driven divided by the numbers gallons of fuel used for a more accurate figure.
 
At 16mpg, I might as well keep my full-size 4wd crew cab truck!

have a 2008 highlander AWD limited. Range from 18-22 in town and 25 highways
 
A few comments I run synthetic oil and keep tire pressure up at the maximum. The transmission the highlander allows you to shift to neutral going down a hill and then back in when you need power, so if you drive it like a stick it can save you some gas mileage.
 
Best highway mileage seems to be around 60 MPH ( up to 27 MPG on a long trip, but that is slow) , If you buy gas the has ethanol in it will reduce you MPG About 5 MPG.

Actually you use more gas coasting in neutral than you do coasting in gear. In neutral, you're burning gas to keep the engine running. In gear, the coasting keeps the engine turning and the fuel injection shuts down.
 
Counter-intuitive, I know.
 
Plus coasting in neutral is illegal most places since it's not the safest practice.

I said going downhill not costing.Going downhill in nuetral no transmisson breaking , speed increases ( M=M*V) all with less fuel, MPG computer of the highlaner engine RPM's drop & real time MPG indicator shoots way up. Could be
 
As far as it being illegal to shift my car how I want thankfully I do not live in that part of the USA. Yes I am a good driver and don't tailgate etc. .

Going downhill in neutral uses more gas than going downhill in gear. The drivetrain isn't turning the engine in neutral so you have to burn gas to keep the motor running.
 
Going downhill in gear, the drivetrain turns the engine over and the fuel injection shuts off.
 
Electronic gas gauges or a Scangauge II aren't going to be accurate in that situation I don't think.
 
Hypermilers will disagree.
 
Oh yeah, others say that going downhill in neutral is not good for your transmission; something about not getting oil to the gears.

If you're in neutral then you're coasting whether it's downhill, uphill or flat.
 
Going downhill in nuetral no transmisson breaking
 
I'm glad your transmission isn't breaking but I think you meant braking.
 
( M=M*V)
 
M = M*V ?? Therefore, V = 1?
 
all with less fuel
 
And you do this while not exceeding posted speed limits?
 
Yes I am a good driver and don't tailgate etc.
 
An uninformed person might regard your position as an oxymoron arguing that you cannot be a good driver without your transmission engaged.
