Automatic Heating Fuel & Propane Delivery 

  Automatic Delivery option utilizes our fuel management software to analyze your past delivery history with current temperatures. Based on your tank size, we calculate when your Heating Fuel or Propane Tank should be due for a delivery.

Automatic Delivery provides peace of mind that you will not run out of Heating Fuel or Propane.

Diesel Exhaust Fluid - DEF 

  With the ever changing emissions regulations for cleaner burneing engines and motors, one technology has become common in Diesel powered vehicles. Selective Catalytic Reduction or SCR. This technology injects a Diesel Exhaust Fluid (DEF) into the engine systems exhaust which turns the harmful Nitrous Oxide into Nitrogen and water vapor. DEF is a pure, aqueous solution of urea. Stored on board the vehicle, it is injected into the system for a cleaner burning exhaust. If your vehicle or fleet requires DEF, we are a distributor of the Air1 brand fluid. Air1 brand DEF is available at all of our locations, including our Last Minit Mart conveinence stores. Avaliable for immediate pickup at most locations, sold in 1 gallon & 2.5 gallon bottles.
