Propane tank refills Monday – Friday, 8am-5pm at our propane station. At Jackson Oil, we can refill any propane tank large or small at our facility. We can fill different shapes and sizes as long as the tank is not expired. Refilling a propane tank is cheaper than exchanging. If you exchange your propane tank, you do not receive credit for anything you had left in the tank. Get your tank refilled by one of our professionals and pay for only what you need. Tanks expire 12 years after the expiration date that is stamped into the metal collar around the valve at the top of the tank. Expiration occurs at the end of the month that is stamped on the tank. At that point it would either need to be recertified or disposed of and a new tank purchased. When a tank has been recertified it will have another date stamped or engraved into the same general area and will then be good for another 5 years after the last day of the month of recertification. Jackson Oil does not recertify tanks. There are companies such as Ferrellgas and Amerigas that will recertify a tank for under $20.
