Conventional Non-Ethanol Gasoline

With today's gasoline containing certain percentages of Ethanol, some small and older engines may not function properly with the amount of Ethanol in the gasoline. This can result in poor engine performance. Our suppliers have recognized this problem and have recently starting offering a Conventional grade of Gasoline that is much like gasoline that was available several years ago, containing no Ethanol. This Conventional Non-Ethanol Gasoline, or sometimes referred to as Recreational Gasoline or Rec Gas, allows these types of motors and engines to perform in the way they were intended. This Conventional Non-Ethanol Gasoline is also available in three octane grades depending on your need and availability from our suppliers (87, 89, and 90 Octane). If you are experiencing issues with the standard Ethanol grade Gasoline in your small or old engine, this Conventional Non-Ethanol Gasoline may be your answer.

Diesel Exhaust Fluid - DEF

With the ever changing emissions regulations for cleaner burneing engines and motor, 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 system's 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. For larger quantities of DEF we offer 55 gallon drums as well as 275 gallon & 330 gallon totes. For large fleet management DEF is also available by the bulk tanker loads to your location and storage tank.

Please visit the Air1.com website for specific product information or nationwide distribution locations. You can also download the Air1 Mobile App!
