Do you even know what the RON number stand for? I can bet 99% dont even know what it is for. And to those idiot that say using RON95 causes your car to catch fire easier, please go shoot yourself in the head before you spread more of your stupid facts on the internet.

RON stand for Research Octane Number and it is an indication of the fuel's resistance to auto-ignition or better known as pinging. Pinging occur when the air/fuel mixture ignites prematurely in the cylinder before the piston reaches TDC. The higher the fuels RON number, the better the engine performance as the ECU does not need to retard the ignition of the fuel mixture too much to prevent premature ignition.

EFI engine have no problem as their ECU can auto-calibrate but carburettor engine might need to be retuned to take RON95.

No such thing as faster engine wear and tear if using RON95. But what I can see among all the fuel companies, BHP and Esso/mobil fuel perform best cause they add alot of friction modifier additive. Just a tip to save you money.

You can choose to continue being ignorant. No one is stopping you cause in the end, you are the one paying for the fuel. I work in the downstream Oil & Gas business so I know my facts. At least backup with facts and dont just rely on your gut feeling. I think I spoke too much, better to keep it to myself.

if you think I copy from Mr wiki, then so be it. I dont need to prove anything to people like you

its cause ur engine is sucking in warm air which is less dense with oxygen. at night when air is cooler u can feel the engine perform better cause cold air is denser

When you dont know how the oil industry work, better to just keep your 2cent to yourself. Fuel formulation is subjective and dependent on different oil companies and we dont add additive to boast RON92 fuel to RON95.

Not only it is more expensive to do so, its completely stupid to produce RON92 fuel and then later
add additive to boast the octane number. Doing so would make your fuel product inconsistent, not to mention the extra hassle. Daily production for a typical refinery runs up to millions of barrel per day and each barrel is around 42 gallon.

This thread is a waste of space. Reading some comments really give me brain damage.

RON95 is gonna stay no matter whether you change the government or not. It is not simple to change the formulation and it is not an overnight process. No doubt the technology is there and we can even refine it up to RON99 just for the lulz but why do that when fuel prices in malaysia is controlled and fixed. RON99 is not gonna give your crappy city car a 20 hp boast or what. Its a waste of money to refine it to RON99 when 90% of car cant utilise the fuel.

If you are so paranoid about RON rating in your fuel, you can go add benzene,toluene or xylene in your fuel tank yourself. Your fuel RON would be boasted up considerably.Benzene has a RON100 rating. But mono-aromatics(benzene,toluene,xylene) are toxic so you bare the responsibility yourself.
