The tank for my oil heat furnace is going on 60 years old. I'm
beginning to worry about internal rust doing it in. I guess it would
start as a drip but it's where it can go for weeks without being

tank, is there anything I should do?

Check your insurance.

Specifically check if it has a clause which will pay out *only* if oil that
has leaked leaks onto a neighbour's property. If so, if the thing leaks
but it stays on your property, you pay.

Then check out the cost of cleaning up a spill.
