You probably live in a dryer climate than Oregon... Here an empty steel

Not to mention an empty fuel tank can be more dangerous than a full
one (fumes). But the rate our prices are going up, I may just store
petrol at the bank!

No fooling. I'm fortunate (or not) to have a ford V8 truck that will
eat most any gas that I put in it. I've used it to dispose of all sorts
of less than fresh gas (mixed 1/3 with 2/3 fresh.)

I won't run my 1100 Yamaha on gas more than a month old. If I don't
ride it over the winter, its gas goes into the Ford.

Another way to go would be to drain the entire fuel system then put a
few ounces of 2 stroke oil in the tank and throughly splash it around to
protect the tank from rusting. My tiller and boat motor have plastic
fuel tanks so I just store them dry.
