Superior Propane offers four propane refill options. 1. We can take empties and exchange them for full propane cylinders. Cylinders must be rented from us. 2. You can fill the cylinders yourself with a rented dispenser. Cylinders can be ours or yours. (This option requires training.) 3. Depending on your location, we can come to your site and refill the cylinders. Cylinders can be ours or yours. 4. You can come to Superior Retail Outlets, where applicable.
