isnt the gas stored at 15degrees celsius...at least that's what the pump says at my local Shell station. "volume corrected to 15degrees celsius"

One factor is that you have less gas and less weight .
Any other factor for putting 1/4 - 1/3 of the tank capacity apart weight reduction?

Well less weight is always better.. I'm not suggesting at anything, but if you see what drag racers do just before a race (either use their gas tank until only about a quarter is left or use it all then fill up to about 1/4 or less with high octane gas), it's the same thing.
Fresh gas is always more potent than one that's been in your tank, say 1 week, unless the gas station is storing it bad. Motorbike riders (esp. scooters) notice this the most with their butt dyno
Everyone should fill up their tank to a level that they know they'll need or is convenient for them.
Also, more frequent filling has the advantage of getting fresh gas more often.

- So if you're storing the car for winter, fill it up.
- For long trips, of course fill it up.
- If the gas station is next to your house and all you do is go to work and come home, you might as well not fill over 1/2 your tank so there's always less weight being carried around.

I told him I read otherwise.
He told me that using synthetic is what he was supposed to tell me.
I just did the airbox baffle delete about ten minutes ago and noticed my top end was smoother. Then I happened upon this thread and realized i'm 1/8 short of a full tank. Baffles or tank?

That's a different topic but I didn't want to insist on always filling in small amounts.
It's been discussed many times for storing your car in the winter that filling your gas tank is best to reduce any moisture buildup. If you're in that situation, might as well use Stabil too (so your gas doesn't expire as fast). It's a compromise, but you'd rather have a car with little response from old gas after the winter is over than have water being injected in the engine.

Well,
I always wondering how come?
Always talking for performance in a straight line. How come every time I full up or almost full my tank the car seems to pull stronger?
Is it related to the fuel pressure ? Is it placebo? I would expect the opposite because a full tank means extra weight which means lower performance !

Subjects would show up with their cars, tanks 1/4 full. They'd get out and give the car to a tester, who would drive it to a gas station and then bring it back - gas gauge taped over. Half the cars would be filled up; half wouldn't get any gas. Subject wouldn't know if the tank had been filled or not.
Subject takes his car for a test drive and then has to indicate whether he thinks tank was filled... or wasn't.

1) That was the old days. Gas is regulared by elect. meters. They will heat the gas up to a certain temp. Yiu can tell when handle gets warm. The gas companies aren't going to loose any money.
2) Unless your tank is a weird shape. The cubic inches that are exposed to air air is relatively the same. So same evaporation. You'd have to have an inverted "V" to see your affect. "^"

I find myself more likely to WOT during the first quarter of a tank, so the car tends to be quicker for the first quarter of a tank. nothing to do with increased horsepower though.

True. However, I am new to the 6 speed and this is my 3rd full tank and too am experiencing this.
Dont know? Could be. After all some guys on the track suffer from fuel starvation when low on fuel that is.

i don't know, i've been driving the car for over 4 years, and it's always seemed that way to me too. Definitely seems to pull stronger after being freshly fueled.

Seriously.. FML..
I don't know but I drive the car hard when it's on full and when it's about to just stop because of no gas.. I get the same performance..
But on some fill ups, I do get that bonus push.. Like +10 hp added.
