I only run this mower on car LPG and fill the BBQ bottle myself from discarded car LPG tanks so doesn't cost anything for fuel.
Online there are a few places that are happy for you to take away old car LPG tanks and they usually have 10 to 20 litres still in them .Scrap yards and tips also have a few bottles ,but I haven't needed to collect any bottles for years as I still have a few with gas . If I had to buy LPG I would fill a fork lift tank at the servo and fill the small bottle from that as you would still save at least 50 percent in running costs and LPG does't go off so it will keep for decades.
In summer with a petrol mower the 1/4 of a tank of petrol left after mowing usually evaporates away by the next time you use the mower but with LPG you have no loss of fuel from evaporation.
I haven't seen LPG mowers for sale in Aus but in the UK and US they are available .
Didn't think anyone else would want one but I will get to use up some old LPG and haven't noticed any difference in power with this LPG mower.
