Premium, 95-octane unleaded petrol Premium unleaded 95 petrol (PULP 95) is a type of unleaded fuel that is designed to be more fuel efficient and cause a smoother engine operation, which in turn improves performance. It is meant for use by imported and high-performance vehicles, but can be used by the majority of cars.

This is primarily used by more high-performance cars, but it can also be used by most vehicles on the road. The main difference between unleaded 91 and 95 is that the premium unleaded fuel can resist pinging longer which is better for the engine.
Regular fuel has a lower octane number 87, while Premium generally gets a 91 octane rating or higher. “Octane number”, is a measure of the ignition quality of fuel. Higher this number, the less susceptible is the fuel to 'knocking' when burnt in a standard engine.
Petrol. The petrol fuel standard describes the parameters of 91 Research Octane Number (RON) and 95 RON petrol. 98 RON petrol must meet the 95 RON standard.
Otherwise known as Ultra-Premium by some brands, 98 is the highest-octane fuel currently available in Australia. Unleaded 98 provides higher engine power and overall performance in comparison to 91 and 95. It is also responsible for less pollution, according to providers.
There is essentially no difference between premium gasolines. It's all marketing. I can say that after 35 years working in the oil industry. Not only is there no real difference between premium gasolines, the only difference between premium and regular is octane rating.
According to NRMA motoring expert Jack Haley, on average 95 RON can give around 4 per cent lower fuel consumption than 91, assuming the engine computer adjusts to take advantage of the octane difference.
In Australia, most petrol stations offer a range of fuel types (E10, 91, 95, 98). These labels are what's called the Research Octane Number (RON). The RON is really just a fancy way of indicating how well the fuel will resist burning too early inside your engine.
If 91 is used in cars requiring higher octane fuel, you run the risk of pre-igniting or "knocking". This occurs when the petrol combusts early and pushes down against a piston while it is still moving upwards during the compression stroke.

So can you put 91 octane petrol in a 95 octane car? Yes you can - but only if absolutely necessary.
Mixing the 95 and 98 octane fuels will not cause any problems.
Mixing the grades to get 91 or so shouldn't hurt, but it probably isn't saving you much money. Using anything higher than your manual recommends probably won't help your car's performance – but using lower might save you a few bucks, Leroux says. If you notice knocking, you should switch back.
Some high octane fuels have cleaning additives or detergents that can help to keep the engine clean and run better so this may help to clean out your engine. But for prolonged use, you're unlikely to see a marked return on investment unless premium fuel is specifically advised by the manufacturer.

It's a lot about additives. I rate BP Ultimate diesel as best all-round for fuel economy as well as fuel system treatment. Shell V-Power diesel has the best lubricity for the fuel injection pump but does not achieve quite the same economy.
98 petrol can withstand this, allowing the engine to extract the maximum amount of power from the fuel and run at top power. If you used 95 petrol instead, it would explode too quickly under the pressure.
To put it into context, in Europe, Japan and the United States, the maximum level of sulfur permitted in fuel is 10 parts per million (ppm). In Australia, its 55 ppm for premium unleaded petrol and 150 ppm for regular unleaded petrol - 15 times the international standard.
Gas brands differ according to detergent additives used to prevent carbon deposits from accumulating in your engine. “Top Tier” brands are known to use more detergent and/or additives than the EPA requires. This is to support better engine performance and fuel economy by reducing carbon deposits.
In May 1995, Ampol and Caltex merged petroleum refining and marketing assets to form Australian Petroleum Pty Ltd which, in 1997, became Caltex Petroleum Australia Ltd, the largest refiner-marketer in Australia. The company now housed three iconic brands: Ampol, Caltex and Golden Fleece.
