Petrol, also known as gasoline or gas, is a mixture of volatile, flammable liquid hydrocarbons derived from petroleum. It mostly used as fuel for internal-combustion engines1. It is also used as a solvent for oils and fats1. Petrol has different octane ratings, which indicate how well it resists burning too early inside the engine. The higher the octane rating, the more resistant the petrol is to knocking, which is a condition that reduces engine efficiency and can cause damage2.
The most common types of petrol in Australia are unleaded 91 (ULP 91), premium unleaded 95 (PULP 95), premium unleaded 98 (PULP 98), ethanol-blended E10, and ethanol-blended E852. ULP 91 is the standard petrol that can be used by most cars. But some imported and high-performance vehicles may require PULP 95 or PULP 98 for better fuel efficiency and smoother engine operation2. E10 and E85 are more environmentally friendly options, as they use a corn or sugarcane based ethanol blend, instead of 100% refined oil2. However, not all cars are compatible with ethanol fuels, and they may also have lower fuel economy than pure petrol2.
What type of petrol should be used?
The type of petrol that you should use depends on your car’s specifications and preferences. You can check your car’s owner’s manual or the fuel flap to see what kind of petrol is recommended or required by the manufacturer2. Generally, it is best to stick to what the manual says, as using a lower octane rating than required can cause engine knocking. While using a higher octane rating than required may not provide any noticeable benefits2. You can also compare the prices of different petrol types at your local petrol station or online, and see if you can save money by choosing a cheaper or more efficient option2.

Other uses of petrol
Petrol can be used for many other purposes apart from being used as fuel for internal-combustion engines. According to the web search results that I have access to, some of the other uses of petrol are:
- As a solvent for oils and fats1.
- As a raw material for the production of plastics, paints, synthetic fibers, rubber, and other petrochemical products123.
- As a component of detergents, dyes, cosmetics, pesticides, fertilizers, and medicines23.
- As a source of energy for heating, lighting, and electricity generation3.
Petrol is a very versatile and useful substance. But it also has some negative impacts on the environment and human health. When petrol is burned, it releases toxic gases and high amounts of carbon dioxide, a greenhouse gas. that contributes to global warming3. Petrol also poses a risk of fire, explosion, and pollution if it leaks or spills. Therefore, it is important to use petrol wisely and responsibly. What’s more? Look for alternative sources of energy that are more sustainable and eco-friendlier.
