Mine holds 22.5 gallons usable fuel. Different years held different
amounts, but I believe that all hold between 21 and 23. Mine burns 5.6
gallons per hour at 2500 rpm on the tach. Most are in the 6gph range
when properly leaned. Mine burns about 9gph in full power climb, and
about 7.5 gph in maximum economy climb.
Basically that gives me a range of slightly more than 4 hours, with
no reserve. My longest legs are usually about 3 hours. That rpm will
produce about 93 knots.
I have a 150J with an O-200A engine.

The ones I fly take 22.5 gallons of USABLE fuel. That is conservatively
4 to 4.5 hours of flying. I have never run the tanks low enough to find
out exactly how long they will run. One pilot did, and he had to put it
down in a field. The plane was out of commission for 3 months.
I knew it was something like that. I remembered it was just enough to
make you think you could fly from LA to the Bay Area on one tank of
gas, and not quite enough to make it. :-(
There was an FAA advisory out a couple years ago on that problem.

Jackie Murry better be prepared for a lot of off field landings. I flew fire patrol in a 150 all summer, and with it properly leaned, I burned 5.5 gph. At this rate I could only fly for 4.09 hours before the tanks ran dry. This is not including the FAA required 30 minute daytime reserve. I wouldn't suggest that anyone fly a C-150 for more than 3.5 hours unless they have long range tanks.

I would also like to add that when flying 150/152s to near the limits of
their endurance, be extra sure that the tanks are filled to the very tippy
top. Those tanks are very wide and shallow, and every gallon is another
ten minutes in the air.
I recently made a mistake that I lived through, but won't make again.
Upon checking the tanks of a 152, I noted that they were filled to a little
lower than the rim. Barely a half an inch. After flying for 3.0 hrs, in
an airplane that burns 6.0 gph, I expected to have 6 gallons usable left:
30 more mins, plus the legal 30 min reserve. When they fueled it back up,
I saw that it only had 4 gals usable left -- if I had flown for the
maximum expected ability, 3.5 hrs, I would've had only one gallon left!
That little half an inch was a gallon in each tank!

Also you want to make sure the airplane is sitting on level ground when
it is fueled - if it is not, it will look like it is full to the rim,
even though it is not.

Depends on the speed. The 150J can stay up over 6 hours at 70 mph. At
cruise, you are, of course, correct. The POH claims 4.1 hours with no
reserve and no alowance for climbout. I have found the POH to be fairly
accurate.

Average is a rough question to answer but most Cessna 150's have 25
gallons total and 22.5 usable. Some that have been fitted with long
range tanks may have more. I wouldn't try to estimate range because too
many variables effect it....such as power
setting,altitude,mixture,wind/ground speed ,just to name a few. One
suggestion,figure range in terms of worst case..I use 150% of fuel burn
and figure a minimum of an hour and a half for a reserve. In other words
if the book shows 6.0 gals/hr,I figure 9.0 gals/hr fuel burn. I know
this is very conservative but many GA accidents are caused by fuel
exhaustion. I'D RATHER MAKE AN EXTRA FUEL STOP THAN TRY TO BURN AIR IN
THE TANKS!!!!!

So, to you, a Cessna 150 can stay in the air about an hour? You're not
going anywhere around here with that attitude. A run up the Hudson River
exclusion (for example) takes about 1.5 hours, and they take a dim view
of 150s landing at Newark to tank up.
Now, this rule might be a good one to follow the first time you fly a
particular aircraft, but once you tank it up a couple of times, you'll
know what it takes.
