Whenever we Malaysian drivers stand in front of a petrol pump, we see quite a few options in front of us. Regardless of which petrol brand we use, each one offers selections that are differentiated with abbreviations and numbers such as “RON 95” or “RON 97”. We may be surprised, however, when we visit other countries and see that their petrol pumps offer different options with labels like “MON” or “AKI”. But do we really know what all of these terms mean? The truth is that not all fuels are equal, and we should be using the right fuels that are rated for the engine we have in our car.
