Heating oil storage tank life expectancy:

What is the typical life of above ground oil storage tanks and what factors influence that tank lifetime? We describe the life range of an AST and what affects its service life then we continue with a discussion of the life of underground tanks.

This article series discusses the typical life of oil storage tanks such as tanks used to store No. 2 home heating oil. Both above-ground oil storage tank life (AST life) and underground storage tank life (UST life) and the factors that determine the life of those tanks are explained. In a discussion of maximizing oil storage tank life - that means minimizing the risk of an oil tank leak - we describe things that can shorten the life of an oil tank can be avoided or corrected. The photo at page top shows how a leak develops and appears in an indoor oil storage tank, forming a stalactite of oil and sludge hanging from the bottom of the tank.

Because an oil tank often rusts through from the inside out, the exterior of an oil tank may look fine but in fact it could be paper thin and easily punctured, even by a finger!

The life expectancy of oil tanks is helpful in planning for storage tank testing and storage tank replacement. This article series is a section of "Heating Oil Underground & Above ground Oil Storage Tank Leaks, Testing, Problems & Solutions, Home Buyer's / Home Owner's Guide" which offers extensive free un-biased oil storage tank inspection and testing advice for property buyers and owners.

Life Expectancy of Above Ground Oil Storage Tanks - indoors or outside

We suspect that there is a wide variation in indoor above ground and outdoor above ground oil tank life due to the considerable variation in both the quality and thickness of oil tank steel (older tanks seem to have been a heavier gauge steel), as well as other factors in oil storage tank life.

We have seen indoor oil tanks easily in good condition that are 60 years old or older, and we have found failures in newer oil storage tanks that may have been made of thinner or cheaper steel and that did not last as long as the original ones.

Rather than guess at oil tank condition, we suggest that if your home has an older above ground oil storage tank, ten years old or older, you should
