Car Fuel Choice: What Every Car Owners In Sydney Must Know


The responsibility of a car owner starts when the vehicle is out of the shop or dealer’s warehouse. One of the most important things that you need to understand is filling in your car engine with the right fuel. In as much as Australians love to drive and go for adventures, it’s equally essential to always be careful when fuelling your car. 


At some point, you may have been wondering what the numbers 91, 95 or 98 mean when you are fueling your car. Well, you’re not alone. Some people experience this as well, especially those who are first-time car owners. To shed a light on this matter, we’ll discuss the different types of car fuel and how important it is that you choose the right one. 


Car Fuel Types

Probably, you’ve heard about petrol, diesel, and gasoline countless times. Well, these are the most common types of car fuel and we’ll discuss each one of them moving forward. 

In connection with this, it’s paramount that you are aware of your fuel’s octane level. The Research Octane Number (RON) determines how much resistance fuel has to ignite in your engine. This is what you normally see when you are filling up your car - the numbers 91, 95 or 98. Take note, the higher the octane number is, the more resistant the fuel is to pinging in your engine. So, if you own a high-performance car like a Porsche 718 Cayman/Boxster, then, you need higher octane fuels


Now, here’s a quick run-through of the major fuel types that might help you next time you’re at the pump.


Regular Unleaded Petrol (91)

Regular unleaded petrol has an octane level of 91 and it is the most readily available type of fuel in Australia. Most cars will be able to use it, however, premium fuels may be a better and more fuel-efficient choice, depending on what car you have. 


E10 is an ethanol-based fuel, in that it’s 10% ethanol and 90% unleaded petrol. It’s more powerful than standard unleaded petrol with a RON (Research Octane Number) of 94, however, it can be slightly less fuel-efficient due to the presence of Ethanol. On a positive note, choosing this fuel means that you are also helping the Australian sugarcane industry. Cheers to that!


Premium Unleaded Petrol (95 and 98)

These two are designed to be more fuel-efficient and cause a smoother engine operation that can improve performance. As you can see, the RON (Research Octane Number) is higher. Plus, providers claim that these fuels provide less pollution. Both these petrols are meant for use by imported and high-performance vehicles but can be used by the majority of cars. However, there are cars that only take 98 and not anything else.



E85 is another ethanol option which is considered a powerful fuel often used on V8 supercars. This fuel contains 85% ethanol and only 15% regular petrol which indicates that it is powerful, cheaper and has much less of an effect on the environment. Not to mention,  it has an octane rating of 107.



Needless to say, this is one of the most popular car fuels. It is commonly used in SUVs and work utes. Over the years, it has become an increasingly popular fuel for luxury European brands as well. If your car runs on diesel, you have two options - standard or one of the variously named premium diesel options. There are also biodiesel and premium diesel fuels available on the market. 


Liquefied Petroleum Gas (LPG)

LPG, also known as Autogas, usually only runs in petrol cars which are specifically modified for this fuel type. It is generally considered one of the more eco-friendly types, too. On the other hand, LPG sales have been declining over the past decade and now account for just two per cent of total automotive fuels sold in Australia.

Importance Of Using The Right Fuel Type

Choosing the right fuel for your car is important in making sure your car’s performance is achieved and keep your engine running smoothly as well as maximising its longevity. Failure to do so can have negative effects on horsepower and damage some parts in the vehicle’s fuel supply system. Surely, you don’t want to do that. 


Given this, you need to choose the fuel type indicated in the vehicle’s manual. It contains in-details information about the minimum rating of octane that is compatible with your car

engine. Now, if it tells you that you need higher octane, then choose from 89, 91 or 93 ratings. Experts strongly suggest not to choose fuels with lower octane power than what is described in the user’s manual. 



Surely, after purchasing the car of your dreams, you’d want to drive it smoothly. Thus, be sure to choose the right fuel for your car. In any event that you fueled your car with the wrong fuel accidentally, don’t start your car. Immediately inform the station attendant and call roadside assistance to ensure that this matter is taken care of.
