Previously, the price of RON 95 in Malaysia is RM1.75 per litre. From today onwards, it will be RM1.80 per litre and will be introduced to nationwide. Perhaps the 'red' colour fuel(RON 95) that often people neglected in Shell(as an example) will be the main fuel while the 'green' colour fuel(RON97) that mostly people used will be the premium fuel, increased from RM1.80 to RM2.05 per litre. The previous 'green' colour fuel will no longer can be found easily nationwide, only selected locations and city. I've asked the cashier in one of the Shell petrol kiosk in Miri regarding RON97 which commonly we used, he answered me only Kuching has it, RON97 and V-Power are not available in Miri, until future, perhaps.
What do you guys think about it? 1st thing came across into my mind was that, are we downgrading our daily fuel instead of upgrading to RON99? Then, will the performance of the vehicle become worse? Next, will the engine of the vehicle gets dirtier easily? Worst of all, will it damage the vehicle engine?!
Oh well, after I've Google'd for few minutes, my above assumptions are out of the box, totally wrong! Here's a simple conclusion that I can make after reading few articles. 1st things 1st, RON signifies Research Octane Number. It is a measurement of the fuel's ability to resist engine knocking. Knocking only happens in the engine whereby the cylinder explodes when fuel and air being mixed together. The higher the Octane Number, the harder/higher resistance for the engine to knock, which it will reduces the performance of the vehicle! Thus, don't feel and think bad of using a lower Octane Number of fuel, it's just cheaper and environmental friendly, I think.
