Oregon People: Who else is experiencing "false fills" at the gas station?
The last 4 times I've filled the TT it's been "full" when I leave, and then within a day (less than 20 miles) dropped significantly down. And the last time I "filled" up, the total was more than what my tank can carry. It was over by a little, maybe not enough to account for the gas line and various space extra fuel can hide, but conjoined with the other symptoms seemed fishy. Anyone else? I only fill at Chevrons in the area if that means anything.

with the cap off bounce the bumper up and down to help "burp" the tank
of all that wasted oxygen in the tank.
really i don't know. HOT days more gas larger, cold days gas is smaller. that may explain it.
oh the bouncing the tank up and down is what my dad does. I point and laugh and make fun of him.

Haven't seen any issues here.
I only go to Chevron. Haven't noticed a big drop after filling up. And I've never put in more gas than the tank can hold (even though I typically run the tank pretty low before filling up).
What time of day do you fill up? If during the middle of a hot day, then temps may have something to do with it.... gas (like any liquid) expands as it heats up...so maybe you're "filling" when its hot, and then the next morning, when the gas cools down, it contracts and your tank is no longer "full". I typically fill up late at night, when the gas is more condensed.

Not related to Jdog35's problem, but temp absolutly does affect how much gas you get at the pump.
There is even a bill trying to force retailers to install temp compensation on the pumps at the gas stations. Always buy gas at the coolest point of the day (usually early morning).
"June 7, 2007
Findings:
* The oil industry has known for 100 years that gasoline expands with
temperature. As it warms, gasoline expands by volume but not by weight or
energy content. Since the 1920's, the oil industry has taken temperature into
account for wholesale transactions, and use a 60 degree Fahrenheit standard
when measuring gasoline at wholesale. But the oil industry does not adjust
for temperature in retail sales to consumers. As a result, consumers pay a
Hot Fuel Premium when gasoline temperatures exceed 60 degrees, as they do
during the summer.
* 513.8 million gallons of gasoline sold in the summer 2007 will be attributable
to the thermal expansion of gasoline.
* Consumers will pay a hot fuel premium of about $1.5 billion in the summer
2007."

Yeah - I have read about that bill.
I was under the impression that the daily temp fluctuations weren't all that great but the seasonal ones certainly are and the 60 degree "standard" leaves a lot of room for variations that gas stations haven't been compensating drivers for.

I too was aware of the 60* temperature "standard". I do tend to fill either really early (1-6a.m.)
or on cooler days. Mainly this is out of happenstance though. I seem to notice the Chevrons in my area (Lake Oswego/Tigard/Tualatin) all leave me with this same issue. When I fill up in Portland or down south a ways, I do not have this issue. Just an observation on my part, but still, I hate feeling like I'm getting hosed on top of the $3+/gallon raping.
