Okay, so I needed gas on one of my Syncros. I was in a hurry (of
course), but the gas guage was reading below empty.

I pull and start pumping. First cut off is 15.5 gallons. Well I know I
can almost always squeeze in another gallon after first cut off. So I
switch to trickle mode, despite the high cutting winds.

Did I mention I was in a hurry?

Second cut off is at 16.6 gallons. Yaah, but I had squeezed too hard
and was pumping gas too fast. So resumed trickle mode.

The wind was really cold and I wasn't wearing gloves. I really wanted
to go faster (being in a hurry and all), but last time I got gas I
overfilled (overflowed a little out the gas inlet.) So I had to take my
time.

A bit later on (hands frozen to gas pump) I'm past 17 gallons. Trickle
mode stays going. I glance under vehicle making sure I'm not leaking
from unknown holes in tank. You know I'm in a hurry here of course.

Trickle, trickle. Final (!) cut off is at 18.58 gallons. Hmm. On my
18.5 gallon syncro tank. Hmm. I think I drove to the gas station on
fumes. This is what you get from being in a hurry.

PS. My hand is still thawing out.
