Shell RON95 will caused the biggest fire

30 11 2010

You might have seen numbers like RON97 and RON95 at your neighborhood petrol station. Fuel with a RON97 rating is more expensive. Have you ever wondered what they mean? Why is RON97 more expensive than RON95, and can you use RON95 to save on fuel costs?

RON stands for Research Octane Number, a rating used to measure a fuels knocking resistance in spark-ignition internal combustion engines. Before we attempt to understand this mumbo-jumbo, we have to know what knocking is. Knocking is what happens when parts or all of the air-fuel mixture prematurely ignites before the flame from the spark plug can reach it. This can be caused by ignition timing that is too early or engine overheating, where the heat from the cylinder itself causes the mixture to combust before the spark plug can burn the mixture. This causes a decrease in performance and might also harm the engine.

It is a misunderstanding to think that RON97 fuels produce more power than RON95 fuels, even more so with the fact that in reality a higher RON number means the fuel burns less easily! RON refers to the ability of the fuel to resist knocking and nothing else.

By pumping the RON97 into a car which engine only requires the RON95, all you’re going to get is an emptier wallet – that hardly counts for performance gains via weight reduction!

Engines are designed to have a minimum RON rating for its fuel. Do check your service manual for the minimum RON rating that it requires.

According to time taken for the petrol to be  until no fire, the Mobil and Esso seems to have same petrol properties.

While surprisingly, petronas petrol RON95 can sustain fire in the longest period which is 35.57  followed by Shell at 31.36 sec and BHPetrol at 30.53 sec. The least time for petrol burning is caltex RON95 with 25.36 sec

So Petronas has the highest number, which means will not ignite so easily compared to Caltex for being the lowest. So what does this mean? Does it mean Caltex is the best?

Actually Petronas RON95 is much lower grade than the RON95 sold in other stations such as Caltex or Shell. Because Petronas sell the good grade to others and keep the lousy grade themselves to sell at their own Petronas stations. Lower grade means not easily caught fire. But Petronas RON95 contain more “GAS” than others…so it could be easily ignited.
