[QUOTE="saat, post: 374287, member: 77"] Hello brother. If you follow all the discussions, the info printed in the papers and the data on the interrnet, you will find that what Bro Astroboy is saying is correct. The higher the octane rating the better is the suppression to detonation. Inversely, the lower the RON number the lower is the capability to prevent detonation. You can generally label that a lower octane rating fuel is more "unstable". When we use the term detonation in our discussions here we mean pre-ignition, "knocking" or "pinging" where the fuel mixture "explodes" earlier than desired i.e the fuel mixture releases it energy before the piston reached TDC (top dead center). This condition is very harmful to the engine. Fuel manufacturers formulate their fuel such that higher "quality" fuel has greater resistance to detonation. Please follow the discussion. [/QUOTE]
