How Long Does an Oil Tank Last?

Oil tanks typically last for about 15-20 years, but possibly even longer with proper maintenance and upkeep. Make sure to have your oil tank inspected yearly so you know its current condition and age. Along with an annual tune-up, which is included in each of our Full-Service Plans, make sure to contact us should any unexpected problems arise. 

Service Coverage 

Leave it to us to oversee your oil tank during your annual full-service inspection. However, if you notice any of these problems before your annual check-up, be sure to call us right away. Here are some potential issues: 


  • Rust and dents. Rust or dents on or around your oil tank can impact the way it functions. 
  • Instability. Instability is most likely caused by an issue with installation. If you notice the legs aren’t the same length, or your tank sits at an angle, let us know. 
  • Leaky oil. Oil leakage from the gauge or any other part of the tank should be repaired immediately.
  • Faulty alarm. If your tank has a vent alarm, it should go off when the tank is filled. If it doesn’t, that’s a sign that something isn’t working properly. 
  • Broken gauge. A broken gauge means you won’t be able to monitor your oil levels. It’s crucial that your gauge is accurate to get the correct reading.
  • Damage from cold temperatures or snow. Occasionally, snow and ice can make their way into your oil tank. If this happens, let us know and we’ll take care of it.
