    Before this, we already brought to you some information about RON 95 Petrol.And today we want to give some more information about RON 95 by Honda Malaysia.Honda malaysia has released this list of frequently asked questions by owners of both Honda’s and other marques.Many peolpe don’t know that RON 95 is suitable for their car.So we hope that this list of question will help you to understand the new fuel better.All car models are compatible with RON 95 except for Honda Civic Type R.


    RON 95 is not suitable for Civic Type-R

    1. What exactly is RON?

    RON stands for Research Octane Number, which measures the quality of fuel. It represents the fuel’s ability to resist premature & uncontrolled combustion that occurs when fuel pre-ignites before the ignition spark plug.

    2. What is engine knocking?

    Engine knocking is caused by self-ignition of the fuel or air mixture, which is a result of using RON levels that is lower than the minimum requirement.

    3. What is the minimum RON requirement of my Honda Car?

    For all Honda cars produced in year 2001 onwards, the minimum RON requirement is 91. Honda cars are equipped with ‘Knock Sensors’ that detect the octane quality of the fuel used, enabling it to automatically adjust spark timing to prevent engine knocking.

    We advice drivers that bought their cars from non-authorised dealers to check their owner’s manual for minimum RON requirement.


    Others Honda model can use the RON 95 including Stream.

    4. Type-R RON Issue

    It is recommended to use RON97 for Civic Type R because of its high performance engine, as it was tested in Japan with RON100 for optimum engine performance. Please note that this engine version with knock control can also run on fuel with a minimum octane number of 91; but performance and fuel consumption are affected as a result.

    5. What is a Knock Sensor? Are all Honda cars equipped with Knock Sensors?

    A knock sensor is a detector, which identifies engine knocking during spark ignition. When engine knocking occurs, the knock sensor signals the engine operation to slow down the ignition timing that will eliminate the knock, which may result in some power loss.

    All Honda cars are equipped with Knock Sensor.


    RON 95 also suitable for Honda City.

    6. What fuel should I use & what RON works best for my car?

    As long as the fuel used is not below the minimum RON requirement (RON91), it will be appropriate for all Honda Cars.

    7. What is the effect to the engine if petrol of a different RON is mixed together?

    As long as the fuel meets or exceeds the minimum RON required by the engine, mixing is fine & should not damage your engine. (except Civic Type R, recommended RON97). However, do note that different fuel brands come with different levels & types of additives, so mixing different fuels may not provide the optimum performance & efficiency for your vehicle.

    8. Do I have to always pick the highest octane rating petrol for my vehicle?

    Anything above the minimum RON requirement, which is RON91 for all Honda cars will be appropriate. (except Civic Type R, recommended RON97).

    9. Will there be a reduction of fuel efficiency & performance with the use of RON95 from RON97?

    The efficiency & performance will not be affected if the car uses above its minimum requirement RON which is RON91 for all Honda Cars. (except Civic Type R, recommended RON97). Loss of power & fuel efficiency will only occur when the minimum RON requirement is not met as the knock sensor signals the engine operations to retard its spark timing to eliminate engine knock.

      ni la payahnye pkai kete high performance…pasal RON je keter da jd problem…yg kete honda biase ok la…kecuali type R mmg minimum pn nk pkai RON97…lg satu,Evo X pn kene pkai RON97 gak…bingung gak ek kalo pkai kete sport nih…tp masih ada lagi stesen minyak yang masih menjual minyak RON97…

      Let me share additional information:

      RON-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 RON92 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.

      Simply go to

      and you will understand more.

      Additional info for older cars:

      Over time thanks to normal wear and tear, especially on older cars fitted with carburettors which do not deliver the right amount of fuel as precisely as compared to fuel injection, your engine’s combustion chamber might have been “modified” by the dirty carbon deposits caused by the a less than perfect combustion process. Carbon deposits increase the compression ratio because their bulk volume reduces the volume of the combustion chamber at Top Dead Centre and in the end if your engine is tuned to have a minimum of RON95, it may end up knocking thus requiring a fuel of higher than the recommended RON.

      ron97 masih lagi dijual lepas 1sept nie… tapi harga dia jadik rm2/L

      heheh.. keta peugeot pon cam ler keta lajuuu… mike pon takleh pkai ron95
