What is the life expectancy of an oil storage tank?

The life expectancy of an oil tank varies greatly depending on the material from which it is constructed, its function, the way in which it was installed, and the way in which it is maintained.

Plastic oil tanks typically have a 10-15 year lifespan, supported by a 10-year warranty in the case of many major oil tank manufacturers. The lifespan of these containers can be affected by a wide number of factors, including the design (bunded tanks tend to outlast single skin tanks), conditions, and maintenance. Regularly maintained plastic fuel tanks can last for up to 20 years.

Steel oil storage tanks are generally thought of as a longer-lasting, more durable alternative to plastic tanks – though each material has its pros and cons. Steel’s natural resistance to damaging factors such as UV exposure, temperature change, and accidental damage assist greatly in extending its expected lifespan beyond the expected lifespan of most other fuel and oil containers, with most lasting up to or beyond 20 years.

These guidelines are highly influenced by the way in which tanks are maintained and installed.
