LP Gas

  1. What is LP Gas?

    LP Gas stands for liquefied petroleum gas which describes propane and butane gases. When stored under pressure, they become a liquid and take up much less space, making LP Gas easy to transport.

  2. Why does LP Gas smell?

    As a safety feature, a strong, distinctive odour is deliberately added to LP gas for the detection of even minor leaks.

  3. How does leaked LP Gas dissipate?

    Because LP Gas is heavier than air, any leaked gas will always flow downwards, collect in low spaces and be slow to dissipate without ample ventilation and air movement.

  4. Is LP Gas toxic?

    All LP Gas is absolutely non-toxic, non-corrosive, clean burning and non-polluting. But if inhaled in sufficient volumes it can cause suffocation.

  5. Is LP Gas used to fuel motor vehicles?

    Yes, LP Gas is used to fuel motor vehicles, however a combination of propane and butane (also known as blend) is used. It’s different to heating gas and BBQ gas, which is straight propane.

  6. Can I use propane in my car?

    Yes, you can use propane in your car, however most places don’t sell straight propane because it’s slightly more expensive than blend (propane/butane mix). It’s thought that straight propane is better for your car (in both environmental and in performance terms) and all our branches sell straight Propane so next time you’re going past – pull in, fill up and you be the judge.

  7. What is the mix in blend?

    The mix in blend is a combination of propane and butane normally around 50/50. Blend is commonly used for forklifts and motor vehicles. The exact percentage varies all the time.

  8. How long should a forklift cylinder last?

    Approximately 6-10 hours of operational use depending on the size of the forklift motor and depending on other variables.

  9. How do I get my industrial/LP Gas forklift cylinder changed over for another full one?

    If you currently have a Supagas cylinder and account, simply call your local Supagas location and they will come and change it over for you, next day guaranteed and often on the same day.

What are some basic safety rules?

  1. Ensure that fixed LP Gas installations are carried out and serviced by a licensed or authorized gas fitter. This includes work in premises, on caravans and boats.
  2. Keep LP Gas appliances and fittings in good condition. Make sure they are checked regularly for any deterioration, including corrosion or minor leaks.
  3. Use only equipment and parts specifically manufactured and approved for LP Gas.
  4. Use the correct type of hose. Do not make up temporary connections.
  5. Keep cylinders secure during transport.
  6. Shut off cylinder valve before disconnecting cylinder from the appliance. Conversely when replacing an empty cylinder make sure the appliance isolation cocks are turned off.


  1. Is LP Gas the gas used in BBQ’s?

    Yes, it’s straight propane. It is also used in heaters, water heating systems, cookers and other applications.

  2. What can I do if my BBQ cylinder is out of date (more than 10 years old)?

    Government regulation requires BBQ cylinders to be tested every 10 years. Supagas can have your cylinder re-tested so it’s good for another 10 years. Just drop in and see us or call your local branch for pricing and other details.

  3. How can you tell how much gas is left in an LP Gas cylinder if there is no gauge?

    There is no perfect way to tell but for a general idea, just pour a cup of warm/hot water on the side of the cylinder and because LP Gas is so cold, a condensation line forms and you will be able to clearly see the level of liquid.

  4. How can I tell if my cylinder is leaking?

    You can spray the fittings on the top of a cylinder with a bottle of soapy water when the line is pressurised. If your cylinder is leaking the gas will create bubbles in the soapy water. If this is the case you must turn off the gas supply and contact your gas supplier.

  5. Do I need a regulator for my 9kg BBQ cylinder (or 45kg LP Gas cylinder)?

    Yes, every BBQ should have one as regulators control the pressure of the gas available to the BBQ and allows it to come through at a usable flow rate. The control knobs are only used to adjust the actual volume of the gas to the burners. The suitable regulator is available from our Gas Shop Locations.

  6. How do I get my BBQ gas bottle filled?

    Come into one of our six convenient Supagas locations and we can fill it for you and because we fill from high-pressure tanks it takes only a quarter of the time it does at a service station.

  7. Do we supply Natural Gas in cylinders?

    No, we don’t supply Natural Gas at all.

  8. What is the difference between LP Gas and Natural Gas?

    They are similar in terms of usage, but natural gas cannot be stored and transported as a liquid and therefore is not widely available.

  9. Can I use LP Gas in natural gas appliances or vice-versa?

    No, each type of gas requires different amounts of oxygen to burn properly, so different burners are needed in the appliances. All gas installations and conversions must be carried out by a licensed gas fitter.


  1. What type of signage should I have on the gate with different gases on site?

    It depends on exactly which gas you have on your site, for LP Gas you will require a metal 2YE sign. Phone 13 78 72 to find out more info. Supagas sells safety signs at all of our stores.

  2. What is MAPP Gas and do we have it?

    No, we don’t have MAPP Gas, which is an all-purpose industrial fuel having the high-flame temperature of acetylene but has the handling characteristics of propane.
