Common BBQ tanks can hold 20 pounds, but are usually only filled to 15
or 16 pounds depending on the supplier. I have read that it is safer
that way and is required by regulations. I don't fully understand the
safety issue, but it has been that way for many years.


I have had 20 pound tanks filled by 2 different suppliers. They were
always filled to 19 or 20 pounds.


How long ago? Newer tanks with an OPD will not work very well filled
that much.
