Oh BTW if you ever want to determine how much oxygen is in your gasoline its pretty easy:

The weight percent oxygen in commercial gasoline samples is determined byusing partial least-squares (PLS) regression analysis combined with either FT-Raman, FT-IR, or dispersive near-IR spectroscopy. Calibration models wereconstructed with the use of 33 MTBE oxygenated commercial gasolines. Theminimum standard errors of validation with the use of leave-one-out validationare 0.156, 0.188, and 0.119 wt % oxygen for FT- Raman, FT-IR, and near-IR,respectively. An independent test set of 36 MTBE oxygenated commercialgasolines was used to further validate the PLS models. The minimum standarderrors of prediction for the test set are 0.155, 0.143, and 0.131 wt % oxygenfor FT-Raman, FT-IR, and near- IR, respectively. The wt % oxygen in allsamples ranges from 0.2 to 3.262%.



My head hurts

Both actually, when something heats up the 'little bits' speed up and move apart. When they cool they slow down and bunch together. Using this to your advantage - Pump gas late at night when its cold
the tanks are at least 5 feet under concrete, I dont think they warm up much. Otherwise everyone would pump at night.
You may be right, might be another myth...but somewhat widespread:

"The gasoline you buy -and where and when - can also help you save gas. Buy it during the coolest time of day, either early in the morning or late in the evening. Gas is most dense at these times, and because gas pumps measure volume of gasoline, not density of fuel concentration." - http://www.zmfact.com/cic/reports/cars/highgas.htm

To name a few...I have no idea though, sure density matters but if its too protected to get cold....meh who knows

I'll back DrJay on that theory. I've known about it for a long time.

Automatic transmissions should be allowed to cool down when your car is idling. Put the gear into the neutral position, which reduces the strain on your transmission and allows it to cool off.

In the owners manual it stated you could use 89 octane, but if pinging (detonation) or hesitating occured switch to premium immediately.
My 1997 SSEi says just "Unleaded Fuel Only" on the dash, but on the door to the gas tank filler hole, it says "Use Premium Unleaded Only".
