Liquefied petroleum gas (Autogas)
In September 2019, the government published the Fuel Quality Standards (Autogas) Determination 2019, replacing the Fuel Standard (Autogas) Determination 2003 which expired in December 2019. Under the latest specifications, sulfur content (after stenching) was reduced from 100 mg/kg to 50 mg/kg, and residue on evaporation was reduced from 100 mg/kg to 60 mg/kg.
Full specifications for autogas sold in Australia are available in the SGS INSPIRE fuel specifications database.
