Australia: Fuels: Diesel and Gasoline

Overview

Diesel fuel in Australia are subject to parameters on contents that both affect the environment (such as sulfur and hydrocarbons) and that affect the operability of the engine (such as carbon residue and sediments). Gasoline is subject to similar standards with slightly different parameters. Both standard types have been in place since 2001.

Standard type
National fuel quality standards

Current Standard

Diesel: Fuel Standard (Automotive Diesel) Determination 2001 (10ppm sulfur as of 1 Jan 2009)

Petrol: Fuel Standard (Petrol) Determination 2001 (50ppm sulfur as of 1 Jan 2008)

History

Fuel quality in Australia is regulated by the Department of Sustainability, Environment, Water, Population and Communities. Key regulatory instruments are the Fuel Quality Standards Act (2000) and the Fuel Quality Standards Regulations (2001).

The Australian Department of Sustainability, Environment, Water, Population and Communities maintains all information related to fuel quality (including diesel, petrol, autogas, and biofuel quality) on their fuel quality website.

Technical Standards

 

Diesel

Two groups of standards are applicable to diesel fuels:

  • Environmental Standards regulate fuel parameters that have a direct impact on the environment.
  • Operability Standards address those parameters of diesel that do not have a direct impact on emissions but, if not controlled, can have adverse impacts on the efficient operation of the engine.

Australia’s environmental and operability standards for diesel fuels are summarized below. Complete information is available at the Australian government’s diesel fuel quality page.
