Fuel Types
All fuel sold in WA must comply with State and Commonwealth fuel quality specifications.  

The WA State Government introduced the Environmental Protection (Diesel and Petrol) Regulations 1999, ensuring WA had the cleanest fuel in Australia, with stringent restrictions on the number of carcinogens and pollutants in vehicle exhaust emissions, creating better environmental and health conditions for West Australians.  Since then, new Federal standards and specifications have been applied to make it healthier for all Australians.

Most of our fuel products sold at petrol stations come from the BP Kwinana Refinery, located just south of Perth.  

Unleaded Petrol (ULP)
ULP is the most common fuel type in Australia for passenger vehicles.  Regular unleaded petrol was introduced in 1985 in anticipation of new Australian Design Rules initiated by the Federal Government to reduce Australia's air pollution. Central to the new design rules was the requirement for all vehicles to be fitted with a catalytic converter.

ULP was produced to allow the new vehicles to operate with the catalytic converter.   Most vehicles built or imported since 1986 and a number of pre-1986 vehicles have been fitted with catalytic technology.   If your car is a pre-1986 vehicle and you are not sure if it can run on ULP, check with your manufacturer first before using ULP.

ULP has a Research Octane Number (RON) of between 91 and 93.

Premium Unleaded Petrol (PULP)
PULP is a special blend of petrol designed to bring high octane, and hence high engine power, as well as knock- free performance to unleaded cars with a high-octane requirement.   Most petrol companies have a specially named version of PULP (for example BP Ultimate and Caltex Vortex)

PULP has a Research Octane Number (RON) of 95.

Diesel
Diesel engines are usually very efficient engines, offering better fuel economy in comparison to equivalent petrol models.  Diesel engines emit very low levels of exhaust hydrocarbons and carbon monoxide when correctly tuned and maintained. The main concern diesel engines raise is the smoke they emit, which can be a health hazard.

Currently the sulphur content of diesel is 50 parts per million (ppm). Under Federal legislation this must be reduced to 10ppm by 1 January 2009.  

Liquefied Petroleum Gas (LPG)
LPG, most commonly a blend of propane and butane, is an environmentally cleaner fuel compared to petrol and diesel. It is the most widely accepted alternative fuel for the automotive sector.

Despite LPG cars having lower fuel economy compared to petrol-powered vehicles, fuel costs will usually be lower, as retail LPG prices tend to be lower than other fuel products.

LPG is the only transport fuel in WA, which currently does not have a Federal Government excise applied to it.   An LPG excise will be introduced in July 2011 in five annual increments of 2.5 cents per litre (cpl) taking it to a total of 12.5 cpl by July 2015.

98 RON
98 RON has a Research Octane Number (RON) of 98.  It is a high-octane unleaded fuel that maximizes engine power and performance, as well as producing less pollution.  It is more commonly used by imported and high performance vehicles

98 RON is promoted as providing excellent fuel economy.  It has low levels of benzene, sulphur and lower aromatics and a sulphur content which is 10 times lower than the national standard for unleaded fuels.   

Biodiesel and Biodiesel Blends (B20 diesel)
Biodiesel is 100% biodiesel fuel and is referred to as B100 or “neat biodiesel”. Biodiesel is made from natural renewable sources and can be blended in almost any ratio with petroleum based diesel. Biodiesel blends are often known by the ratio of biodiesel to regular diesel i.e. B20 means 20% biodiesel and 80% petroleum based diesel. The most common blends available internationally are B5 (a mix of 5% biodiesel and 95% petroleum based diesel) and B20 (a mix of 20% biodiesel and 80% petroleum based diesel).

Biodiesel blended fuel (made up of regular diesel mixed with biodiesel) became available at some Western Australian service stations in 2006.  This product, a 20% biodiesel blend, is labelled as B20 diesel under the price search facility on this website. For more information about biodiesel, visit the WA Department of Agriculture and Food's biofuels website.

Before using biodiesel products, motorists are advised to contact their vehicle manufacturer to determine if biodiesel is suitable for use in their vehicle. Motorists with older vehicles (models prior to 1996) should be aware that there have been reports of minor problems with rubber or synthetic parts in the fuel lines and pump seals as the result of biodiesel use. However, these parts can be replaced with more modern components. Additionally, all motorists using biodiesel should be aware that fuel filters should be regularly checked during maintenance servicing .

Ethanol
Ethanol is made from natural renewable sources and can be blended with petroleum based unleaded fuels. For more information about ethanol, visit the WA Agriculture and Food's biofuels website.

Ethanol is pure 100% ethanol, referred to as E100 or "neat ethanol". The Federal Government has established a maximum limit of 10% ethanol in petrol. Ethanol blends are often known by the ratio of ethanol to regular petrol i.e. E10 means a mix of 10% ethanol and 90% unleaded petrol.

The most common blends in Australia are E5 (5% ethanol and 95% unleaded petrol) and E10 10% ethanol and 90% unleaded petrol). No ethanol blend products are commercially available in Western Australia, however there are currently E5 and E10 products available in other states.

A large number of Australian manufacturers support the use of ethanol blend fuels under their warranties, but consumers that are interested in ethanol are advised to contact their vehicle's manufacturer prior to use. The Federal Chamber of Automotive Industries has a list on its website detailing which vehicles can operate using E5 and E10.

Lead Replacement Petrol (LRP)
Now phased out, LRP (96 RON) was introduced as an environmental alternative for cars that used leaded petrol. LRP was refined to contain no lead, along with lower concentrations of benzene and sulphur, respectively identified as health hazards and pollutants.  Lead was historically added to petrol as a cost-effective way of increasing octane and hence engine power rating and providing a measure of engine protection by way of its lubricating qualities.
