It sits there in the drum waiting to be used. The volatile substances are
petrol deisel kero etc. It is safe as long as the drums do not start rusting
from the outside. Keep out of weather.

My DH has been given three large drums of engine oil (!)

Can anyone advise whether it's perfectly safe to store such a substance
near residences for a long period? Obviously we won't be using it all up
in a hurry and I'm worried about it sparking or vapourising or doing
whatever it is engine oil might do.

TIA,
