Heartland Motorsports Park is proud to partner with Propane Central to fill propane tanks this season. The propane dispenser is located next to the Sunoco Fuel Island. Let an HMP official know that you need your tanks filled, and we’ll have somebody to you in no time. Propane is sold by the gallon at current market price, and can be paid for with any major brand credit/debit card. Accepts most propane tanks that have valid inspection date and in acceptable condition.
