How long do aboveground oil tanks last?
The useful life of an aboveground heating oil tank is unpredictable. Experience has shown that newer tanks made with recycled metals often tend to corrode and leak more quickly than tanks installed many years ago.Tanks that have been treated with a liquid corrosion inhibitor will last longer than unprotected tanks. Tank leaks usually start as slow drips, so it is a good practice to check your tank periodically.
