Some times after some maneuvers.. or continuous pattern work with not that
great coordination.. you may find one tank (wing) heavier than the other
because the fuel is unbalanced. select the heavier (fuller) tank for a few
minutes and monitor to rebalance, then back to "both".

Of course.. training to select one tank or the other for single tank
operations, prepares one for flying other aircraft.

Sorry if this is dumb (I am only at 8.3 hours toward my PPL)...

In the email I got from AOPA ePilot training tips today there is a
discussion of fuel starvation that makes regular mention of the fuel
selector switch. All my flying is done in a CE172 and the first and
last time I worry about the switch is during pre-flight when I confirm
that it is on both. I fly on both and never fly any other way and to
be honest, outside of gravity flow issues when parked on an incline I
cannot think of why one would want to select one tank at a time vs
both.

The POH will answer that.

I bought one two days ago. I should finish reading it this weekend.
Thanks.
