Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
Is premium gas better?
Octane ratings are plastered all over every gas pump, and, contrary to marketing terminology, ‘premium’ does not necessarily indicate a fuel is ‘better’ for your car as much as whether it is ‘right’ for your car.

Which fuel burns faster 93 or 95?
95 PETROL DOES NOT HAVE MORE ENERGY THAN 93 PETROL We tend to think that ’95 petrol’ has more energy than ’93 petrol,’ but that is not true. The octane rating refers to the fuel’s resistance to auto-ignition, or otherwise known as ‘knocking. ‘ Thus the higher the rating, the greater the resistance.
Is 93 octane unleaded a good fuel?
Most high performance cars have turbo-chargers and require higher octane 95 unleaded fuel, while common naturally aspirated cars will run well on 93 unleaded. It’s highly unlikely that a standard car will see any performance gain by using 95 unleaded. So, unless your engine is turbo-charged or you live by the coast, 93 unleaded should be just fine.
Is 95 better than 93?
“While 95 has a higher-octane value than 93, octane is not an indication of the energy content in the fuel, and this is where the myth comes in that 95 is better than 93,” he said. Rather, the octane rating refers to the fuel’s resistance to “knocking”, which is a phenomenon of auto-ignition, where the fuel ignites in an uncontrolled manner.
Is there a difference between 93 and 95 unleaded petrol?
Many motorists wonder whether there’s a difference between 93 and 95 unleaded petrol and which is the better fuel to fill up with at the petrol station. Some argue there’s no difference, while others say that 95 is better for fuel economy and performance – and the answer is both are somewhat correct.
Does a 93 octane car need a turbo-charger?
Turbo-chargers boost the air pressure entering the combustion chamber, increasing pressure.

It’s highly unlikely that a standard car will see any performance gain by using 95 unleaded.
Is premium gas healthier?

Why do turbochargers use premium fuel?
It turns out that turbochargers respond really, really well to the use of ‘premium’ fuel because it allows them to turn up the boost without worry about detonation. The better the knock resistance, or octane rating of the gasoline that is used, the more boost can be safely run in a given engine, and the more power produced.
Do cars really need premium gas?

Do all turbocharged cars need premium gas?
Not all turbocharged cars need premium gas, but it’s a more common requirement among turbos than other kinds of engines, thanks to the way these engines work. The name turbo comes from the turbine these engines use to inject more air into the air-fuel mixture in the combustion chamber.

Does a turbocharged engine increase fuel efficiency?
However, don’t expect improved fuel efficiency if your turbocharged engine gets driven spiritedly or tows heavy loads.

Does fuel make car faster?
The higher octane of premium gas won’t make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
Does high octane fuel make a car faster?
