The question today is about RON, what is it and what's the difference between 92, 95 and 97. RON is an abbreviation for Research Octane Number. The RON is determined by running the fuel in an engine with variable compression ratios and then comparing the results obtained with mixtures of iso-octane and n-heptane. In simple terms, the number after the RON denotes how well the engine copes with compression without detonating prior to ignition.
