Propane Filling Station is a small business dedicated to propane refills in Plano, TX. Most people exchange their propane tanks at a gas station once they are empty. Our propane refill services are cheaper than the exchanges, and we have the equipment to refill any sized tank. We have been in business for more than 20 years, and at a mobile gas station (Formerly Thurston's or 7-11), we have many repeat customers who come from far distances for our trusted propane services.
