so far... by kenlw

approximately 10k on 07 AT EX Cp:
 
27.8 mpg
 
conditions: daily driver in Houston freeway traffic. Stop and go "highway" and bursts to 85mph+ at times to pass idiots, NEVER more than a few minutes of steady speed, at ANY steady speed. Not too much "street-level" (30-35mph) driving, I use the highways and tollways a lot....commute is 31 miles one-way, 62 miles R-T daily.
 
Using whatever brand of gas is on sale.
 
95%+ with AC on. Also 18" HFP kit (extra wide tires).
 
Since I consider this "city" driving, and the advertised value was 30mpg, I'm ok with it.
 
Steady state speed-limit mindful "maxing the mileage" driving just isn't in the game book for me.

I don't think that I'm overfilling the tank, I have filled the tank the same way on my 97 jeep grand cherokee, 06 civic, and 07 civic with no ill effects on any car. The 06 civic also got about 100 miles before going off full. I thought this was normal. Anyone out there care to comment about when your car goes off the full mark??

I generally fuel to the first click and be done with it. It is true that if you overfill, you can damage the emissions system. To keep that from happening would imply that you know a bit more about the technical aspect. Too much to remember for multiple vehicles.

I learned the hard way on a couple of vehicles I've owned. They were like babies - put a little too much in and they would spit it back out at you.
 
Then again I've had a couple of older models (Fords mostly) that seemed to never get full. No matter how many times you squeezed the trigger you could always get a little bit more in it.

Every car we've had in the last 15 years (5 cars) has told me not to top off or overfill.
 
There must be a reason - what would be the motivation for BSing on that?

A lot has to do with the expansion/contraction of the fuel during operation and ambient temperature changes (deltas). So it seems to me to best let the systems do their jobs. I have read in passing it can be as much as 50%. I have no links for the exact %/'s. Also I have read it is best to get unleaded fuel duing the cool of the day vs the heat of the day for that very reason.

Yes I hear you! It also it getting more costly if one takes the car into the dealers'. Just to read codes cost a min of 75. at some places.

gasoline purchase time of day by k5ldb

Like a lot of things fuel will expand as temps rise so you get more bang, or in this case octane, for your buck if you buy in the morning when it's had a chance to cool overnight. That expansion is another reason they say don't overfill. If I know I'm going to drive far enough to burn a gallon or two I'll squeeze in more since I know it's about to go anyway. If I'm just filling and going home, like after a round of store, post office, bank errands. I usually go once after the first click and at the second click off I stop.

If managed correctly, the only real variable we are practically affecting is the RANGE mpg of the gals you over fill. My take is why use brain cells when you dont over fill, the system is designed to do it automatically/seamlessly.
