Here at Superior Energy, LLC, our customer's are on an automated delivery schedule to best ensure that their propane tanks are checked and filled regularly. However, sometimes you may use more propane than our system projects, perhaps all the kids were home doing laundry, or you had the fireplace running for a few cold days, or maybe you were cooking up a storm! You can always check to see how much propane is left in your tank and let us know if you may need a delivery sooner, here's how! And remember, for safety reasons, the tank is never filled past the 80% mark.
