Tank Charts
These charts will show you approximately how much is in your tank. We say approximately because there are so many manufacturers of oil tanks that exact sizes can vary from tank to tank. We are just giving you the best estimate for your tank size.
If you aren’t sure what size tank you have, most inside the basement or above ground tanks are 250/275 gallon tanks. Most underground tanks are 550 gallons.
If you still aren’t sure, you can either call us, or ask your oil driver the next time he is out.
