Autogas is an alternative vehicle fuel that substantially reduces harmful emissions, costs less than gasoline and is almost entirely domestically produced. Propane (C3H8), or liquefied petroleum gas, is called autogas when used as a motor fuel. With more than 23 million vehicles and 11,000 buses worldwide running on autogas, it is the most widely used alternative fuel in the world, just behind gasoline and diesel.  Autogas is a safe, proven alternative fuel. Unlike gasoline, diesel, methanol and ethanol, autogas is nontoxic, nonpoisonous and insoluble in water.


What are the benefits of propane autogas?

  • 1. Over 98% of Alliance propane autogas is produced domestically.
  • 2. Autogas is less expensive than gasoline.
  • 3. Autogas produces fewer harmful emissions than gasoline.
  • 4. Autogas increases the life of an engine.
  • 5. Less vehicle maintenance is required on autogas vehicles, and because autogas burns cleaner, oil changes are required less frequently.
  • 6. Drivers report that, compared to conventional gasoline, autogas provides superior performance and equivalent power.

Where does propane autogas come from?

  • Over 98% of Alliance’s propane autogas is produced in the United States. Propane autogas comes from two domestic processes: it is a by-product of both natural gas processing and the crude oil refining process.

Is propane autogas really an alternative fuel?

  • Yes. Propane is an approved, alternative clean fuel listed in the 1990 Clean Air Act and National Energy Policy act of 1992. It is a fuel that burns more cleanly than gasoline, is largely produced in the United States and lowers fuel costs.

What vehicles are candidates for a propane autogas system?

  • Good candidates for conversion to propane autogas include: taxis, police vehicles, shuttle vans, limousines, town cars, food and beverage distribution trucks, utility trucks and many more. Most Alliance AutoGas customers are fleets because fleets have several key characteristics:
  1. The vehicles travel to a home base regularly, which serves as a re-fueling station.
  2. The vehicles travel a high number of miles every year in a given footprint, which allows fleets to offset the cost of conversion due to fuel cost savings.
  3. The vehicles follow a pattern of makes and models – which allows Alliance AutoGas to focus on achieving EPA certification for select makes and models.

Where can someone fill up a vehicle with propane autogas?

  • Various factors play into this question. Depending on the size of your fleet, a refueling infrastructure could be placed at their home bases from a spill-free dispenser installed and maintained by Agtegra. An alternative option would be to fill at our dispenser located in Aberdeen, SD. Autogas vehicles can also be refueled at any public fueling station designed to dispense propane autogas. 

How similiar is filling up with autogas to filling a car with gasoline at the service station?

  • The process is virtually the same, except the nozzle attaches securely to the vehicle. Propane autogas refuels at roughly 8-10 gallons per minute, the same as or faster than gasoline.

Does converting my fleet vehicles void my factory warranty?

  • No. In virtually all cases, converting a vehicle to autogas with Alliance AutoGas does not void your factory warranty. Our warranty simply supplements a factory warranty to provide coverage for Alliance’s Prins VSI system and its components.

propane delivery

scheduled delivery

We continually strive to provide the best service at the least cost to our customers. To do this, we must find ways to lower our costs of providing the service. One way the customer can help us lower our expenses and provide a benefit to themself is to allow us to fill their tanks automatically.

When you place your account on “keep full”, we watch your tank for you and deliver while on our regular routes. The benefits of this include:

  • no interruptions in your heat and hot water
  • no inconvenience of watching the gauge on your tank
  • no embarrassment from letting yourself run out of propane
  • no additional costs to put an “out of gas” system back in service
  • no additional costs for emergency service after our normal hours
  • peace of mind that you will have plenty of propane in case of bad weather

The best part of this free service is that while you receive all of those benefits, it helps us to control our costs by lowering our mileage, maintenance and overtime as we are not taking equipment and manpower from cost efficient routes to make special deliveries. Please contact one of our offices if you are interested in participating in this free program.

summer fill program

If you are a “keep full" Agtegra customer and your account with us is current, we will automatically fill your tank in the summer when prices tend to be lowest. If not on “keep full,” you will need to contact our office or your propane route delivery salesman to receive your propane fill in the summer. 

transport delivery

Agtegra markets propane in transport loads to those customers with propane storage tanks large enough to hold a full truck load of product. We sell transport loads of propane primarily to commercial and agricultural end users. We have access to a fleet of transport trucks and they are ready and able to service your needs, whether for one load or any number of loads. If you have a large propane storage tank, call one of our offices for a competitive quote on a transport load of propane.

propane pre-payment

Agtegra offers a propane pre-payment plan. When contracting with you for the pre-payment of your propane needs for the coming heating season, we agree to guarantee a specified price for a specific amount of propane to be delivered automatically throughout the heating season. Propane delivered by Agtegra will be applied to your contracted gallons until your full allotment has been supplied. The guaranteed price per gallon starts on September 1st and terminates on April 30th for heating accounts. At that time you will receive either a refund or a credit to your account for any propane prepaid but not delivered prior to that date.

Agtegra offers two types of propane pre-payment plans. You can choose from either a “Full Payment” or a “Down Payment” contract. Propane pre-payment contracts must be signed and paid no later than August 31st. If at the end of the contract period there are significant unused gallons of propane, Agtegra reserves the right to retain a $.10 per gallon cancellation fee.

level pay plan

Agtegra's “Level Pay Plan” is the most convenient way for most customers to pay their propane bills. Based on the amount of propane used the previous year, along with some adjustments for forecasted winter weather and pricing, we will calculate your annual propane cost. We divide that figure into 12 equal monthly payments. While on Agtegra’s level pay plan, you receive a locked in price for propane for the budget plan year. This convenient payment arrangement offers an easy way to smooth out the peaks and valleys in your monthly energy bills.

frequently asked questions

What can I do to conserve energy costs?

  1. Change or clean furnace filters once a month during the heating season.
  2. Contact our service department to schedule an appointment.
  3. Check the heating system and replace old, outdated appliances with high- efficiency models.
  4. Close vents and doors in unused rooms and dampers on unused fireplaces.
  5. Lower the thermostat on water heaters to 120 degrees F.
  6. Install water-flow restrictions in showerheads and faucets.
  7. Run washing machines and clothes dryers with a full load.
  8. Check to see if your attic and basement have the recommended levels of insulation.
  9. Keep the lint filter on dryers clean. Dirty lint filters restrict air flow and can also be a fire hazard.
  10. Seal all leaks around doors, windows and other openings, such as pipes or ducts, with caulk or weather-stripping.
  11. Set thermostats between 65 and 70 degrees during the winter and at 58 degrees when away from the house for more than a few hours. Please note that warmer temperatures are needed for homes with ill or elderly persons or infants.
  12. Install an automatic setback or programmable thermostat.

What can I do to cut my propane energy costs?
You can manage your fuel bills by signing up for our "Budget Plan," "Keep-Full Plan" or "Propane Pre-Payment Program." 

How are propane prices determined?
Propane and other heating fuels are traded on the commodities market, which goes up and down like the stock market. By far the biggest influence on these fluctuations is the cost of the crude oil and natural gas from which propane is produced.

Do propane prices change?
The market responds quickly to any situation that might affect supply or demand. Some examples are unexpectedly cold or warm weather, supply interruptions, or excess production. These changes may be reflected in the wholesale price we pay for the propane that is delivered to you.

Why isn't my tank filled to 100% capacity?
Your propane fuel is delivered and stored in liquid form. Propane liquid, for example, will expand nearly 17 times as much as water over the same temperature increase. As a result, tanks and cylinders are never completely filled with propane-gas liquid. Tanks are filled to about 80-85% of their capacity. This leaves a space above the liquid which allows the LP-gases to expand freely due to changes in temperature.

This leaves a space above the liquid which allows the LP-gases to expand freely due to changes in temperature.

How do I read the gauge on my propane tank?
Not all tanks have sight gauges that are easy to read. Some tanks have old style "roto-gauges" that must be opened at the spit valve and the lever turned to locate the level of the liquid in the tank. Ask your delivery driver to show you how to operate such gauges.

If your tank does have a sight-gauge, it may be located on top of the tank, usually under a protective hood. (Note: please be careful when you lift the hood as insects sometimes nest there.)

For your convenience and comfort, please call your local Agtegra Energy office if your gauge reading measures 20% or less. Better yet, let us put you on our "Keep-Full" plan and you won't need to worry about how to read the gauge on your tank.

How do I determine how much propane is left in my 20# cylinder for my grill? 
On the side of each propane cylinder is a stamped Tare Weight (TW). This is the weight of the cylinder when it is empty. Take your cylinder off from your grill and place it on a scale (like a bathroom scale). The total weight determined by the scale, less the tare weight of the cylinder is the amount of propane (in pounds) remaining in the cylinder.

Why does my grill have a very low flame at times?
The new style "overfill protection device" valves also have an excess flow safety feature built into them. The purpose of the excess flow is to limit the amount of propane that will be allowed to escape from the tank in the event of a rupture or severance of the propane hose or gas line. Sometimes, this excess flow can slug shut if the grill valve has been turned on before the valve on the tank has been turned on. The excess flow senses something is wrong and limits the flow of propane. To correct this situation, simply shut off all of the valves in the system, wait for 10 seconds and start over. The excess flow will automatically reset itself. Start by turning on the cylinder valve very slowly. Then turn on the grill valve and light the grill.

Is propane safe to use in my home?
Propane is a safe fuel to use in your home and business. Propane has a narrow range of flammability and cannot be ingested like gasoline or alcohol fuels because it is released as a vapor from a pressurized container. In addition, Agtegra Energy uses preventative maintenance safety programs to ensure that homeowners understand how to properly maintain their propane appliances and enjoy a healthy, safe environment.

Is propane dangerous to the environment?
No. Propane is an approved, clean fuel listed in the 1990 Clean Air Act and the Energy Policy Act of 1992. Propane is one of the cleanest burning of all fossil fuels. Tests conducted by the U.S. Environmental Protection Agency show that propane-fueled vehicles produce 30 to 90 percent less carbon monoxide and about 50 percent fewer toxins and other smog-producing emissions than gasoline engines. Propane is also not-toxic, so it is not harmful to soil or water.

Is propane really a convenient fuel?
Yes. In the United State there are approximately 70,000 miles of interstate pipelines and more than 25,000 retail propane marketers making propane readily available for most homeowners.

Propane is stored in portable tanks so it can be used in areas beyond gas mains. To fuel homes, large tanks can be buried underground because propane is a non-toxic, non-poisonous fuel that doesn’t contaminate aquifers or soil.

Refueling propane powered vehicles takes about the same amount of time as refueling a gasoline vehicle. Nationwide, propane refueling infrastructure consists of more than 10,000 public and private sites.

Who uses propane?
Propane is a trusted and reliable energy source that is used by millions of Americans each day. It fulfills energy needs by burning cleanly and efficiently, giving consumers more value for their energy dollar. People use propane in and around their homes for furnaces, water heaters, air conditioners, outdoor grills, fireplaces, and appliances; on farms for uses such as pest control, crop drying, and irrigation pumps; for industrial uses such as forklifts and fleet vehicles; and in millions of commercial establishments including restaurants and hotels that depend on propane for heating, cooking, and other uses.
