I have not posted in a long time so I've probably missed a lot. I have packed 23+ gallons in my 07 on occasion, too. I remember thinking the station was cheating me the first time it happened, but then I got another 100 miles out of the tank of gas. I try to fill it as full as possible on extended trips, but it ain't worth the trouble for me most of the time. And I don't really care about the boo-hooing from the EPA. But when I do fill the tank to the cap, I can get 550 miles out of a full tank, which saves me a stop on my most-frequent road trip of 1000 miles. I've been extremely fortunate, I guess, as I always get between 21 and 22 MPG in my daily driving and 24+ on long trips when I'm watching the ECO light. My wife gets 18 when she drives. Your results may vary.

If you cram gas into your tank, you can overload the vapor recovery system in your car and trigger the check engine light.

If you'll read a little deeper, they're actually "boo-hooing" for your car's well-being.
 
You want an extra 100 miles per tank (while not saving a dime) and don't care what it does to your car , be my guest.

>" The book says I have a 20 gallon tank.......then I have to dribble in the next 6 gallons to full 23.5 gallons takes about 7 minutes just to top off. Is this normal."
 
Fuel tanks have an air space built in. They do this by having the filler tube going into the side of the tank rather than the top of the tank. The air space is there for a good reason. It is possible to "cram" more fuel into the tank by picking a pump that allows the Pilot to lean to the right and/or forward. This allows more of the air to escape and be replaced with fuel. Then when the car is level, the fuel tank is over filled.
 
This practice can result in problems with the car, even though the owner is not aware of them. Poor mileage may be one of the resulting problems.
21 mpg is not real good for a 2wd, at a consistent 70 mpg, unless you are driving in the mountains.
 
When you wait for the fuel light to come on and the tank readily takes 17.5 gallons
that is about right. Leaving a reserve of 2.5 gallons when the light comes on.
 
Bad habits eventually catch up with us, one way or the other. For instance: The light comes on, signaling there is about 2.5 gallons left in the tank. We get stuck in a bad traffic jam or the station we are counting on to be open isn't, or....!
 
What is wrong with stopping every once in a while, grabbing a drink, or just stretching the legs and topping off fuel until the click when the tank gets down to 1/4?

My Honda pilot owners book indicates that my 2009 Pilot has a 21.00 US gal. capacity.
 
I drive mostly on the Interstate at 65-70 MPH. My adverage has been 23.5 MPG.
 
My Pilot is AWD.

What part of the country? Most of my highway driving is between Pittsburgh and DC via the Cumberland, MD area (semi-mountainous terrain) and because of that I only get around 19.5 MPG.

Most of my driving is in western NC, I-40, I 26 and I-81 in VA. and into WV to Lewisburg area. Two people with luggage. On a trip to FL I had an adverage of 24.9 mpg. I use cruse control as much as possible. Drive at 60 to 65 mph.

My 2007 AWD has around 18,000 miles on it now. My regular commuting mileage has slowly improved from around 18 to around 20 mpg. Best tank ever was 24.5 mpg.
 
Mine doesn't have the VCM like the new Pilots or the higher gearing like Kip's Pilot.

Joe,
 
There are 225 TSB's on my 03' Pilot.
One of them deals with Engine not reaching operating temperature.
 
http://www.edmunds.com/maintenance/recalltsb.html?styleId=100076605&engCode=6VNA- - G3.5&transCode=AUTOMATIC&mileage=36%2C000&zip=30215&type=tsb&serviceType=#48
 
I still believe that it possible, some of the Pilots are not reaching proper operating temp, This could be something as simple as a faulty thermostat.
 
If it doesn't reach proper temp, it may not lean out like it should and fuel mileage suffer. Don't know if any error code would be registered. Very possible no codes would register because all sensors are dealing with a "cool" engine. So they may not sense a rich condition as a fault, because the temp is still calling for "rich".
 
The Scan Gauge II is the handiest gadget I've found in a long time.
It shows lots of engine data as well as various fuel mileage configurations.
 
I've found that even though the temp gauge in the dash shows the engine to be warm, the actual temp may be in the 165 range. Once fully warm the temp goes to 181-182. Sometimes as high as 190 in heavy traffic.
 
The SG has helped me improve mileage an additional 1-2 mpg over and above the mileage it was already getting. My Pilot, has been averaging 17-19 in local driving. I gave enough throttle to allow the tranny to shift at 2000 rpm without lifting my foot. Surprise to me that allowing the shifts to take place at 2200 rpm, without lifting the foot, seems to have helped the MPG by about 1 mpg local. Much over 2200 and the mileage drops back off again. A couple of other things have allowed the local driving to creep up to 19-21 average.
 
On the "X-way" there is very little difference between 60 and 65 mph. But 70 mph drops mileage about 5 mpg. 80 mph is awful!
 
In local driving, does anyone "KNOW" if the car gets better mileage at 45 while the torque converter is still unlocked, or at 50 when the TC has locked up?
Asked that question because most of my commute route has a 45 mph speed limit. So that question "Bugged" me. Now I actually know.
 
This gauge has more than paid for itself as entertainment. Getting better mileage is a wonderful side effect.

update to post 960
 
# 41 (on above link) states a code P-0128 associated with thermostat insufficient temperature. However, that doesn't necessarily mean the computer will pick up on it. "Little things mean a lot".
