RON95 vs RON97 different

RON 95 and RON 97 are two different grades of gasoline (petrol) fuel. RON stands for “Research Octane Number” and is a measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine.

RON 95 gasoline has an octane rating of 95 and is a lower-grade gasoline compared to RON 97. It is typically less expensive and is the most commonly used gasoline in many countries. RON 95 is suitable for use in most vehicles with a gasoline engine.

RON 97 gasoline has an octane rating of 97 and is a higher-grade gasoline compared to RON 95. It contains a higher level of octane-boosting additives, which make it more resistant to knocking and pinging during combustion. RON 97 gasoline is often used in high-performance or luxury vehicles that require a higher level of fuel quality to achieve optimal performance.

It is important to note that using a higher-grade gasoline than required by your vehicle may not necessarily result in improved performance or fuel efficiency. In some cases, it may even cause damage to the engine. It is always best to consult the owner’s manual or consult with a qualified technician to determine the appropriate grade of gasoline for your vehicle.

RON95 vs RON97: Which is more batter for you?

We as road users travel almost every day and it has become part of a common and integral daily activity of our lives. For those of us who drive a motor vehicle, it is essential that we consider the longevity of fuel range and efficiency. Choosing the right fuel has a significant impact on car performance and its useful life, as well as financial savings.

The 2 most common types of fuel are RON95 and RON97, but how do they differ? Before we get there, we should understand the fundamental concept of RON.

What is RON? And what is the difference between 95 and 97? For starters, RON stands for Research Octane Number. A what? Basically, it describes the behaviour of fuel in the engine. Particularly during lower running temperatures. Also to note, having it is an attempt to simulate acceleration behavior for both low and high speeds. As for the differences between RON95 and RON97, the results are rather interesting.

What does RON represent?

RON is an abbreviation for “Research Octane Number”, a form of fuel quality and performance rating. RON determines the fuel’s ‘anti-knock’ quality or its resistance to pre-ignition. The higher the octane number, the more compression the fuel can withstand before detonating.

A higher compression ratio gives an engine a higher horsepower per engine weight than one with a lower compression ratio — making the engine “high performance”.

RON 95

Probably the most commonly used variation of petrol, RON95 serves as the cheaper and value for money offering in the market. Known to many as the “yellow” pump, RON95 provides generally better fuel consumption for most car owners, which also means longer range for car owners. However, RON95 isn’t perfect as it does suppress the power output of the engine. Depending on some owners, if there isn’t much power, they’ll end up accelerating harder. Thus, creating a negative impact on the fuel consumption.

Ron 97

The other popular fuel choice comes the form of the “green” pump, or RON97. This particular fuel configuration is made more for the power user. When it comes to actual day to day usage, RON97 soldiers on as the fuel of choice. Why? Because it provides the best blend of performance and fuel consumption for most users. By most, I’m referring to users with cars that have an engine size larger than 2.5 liters. For those with engines smaller than that, it would be more of a waste of money. Which brings me on to the downside of using RON97, the price. Currently in Malaysia, there is no fixed pricing for the said petrol configuration as it fluctuates according to the week which means that it can be lower and higher depending on the figures added by the government. But even so, it is still significantly more expensive than RON95 which has its pricing fixed.

  • Is RON97 better for engine?
Generally, fuels with a higher octane rating (e.g. RON97) are used in high-compression engines that have higher performance. Higher octane fuels are used for motor vehicles with higher compression ratio. As a general guideline, RON97 is usually recommended for motor vehicles with an engine capacity 2,500cc and above.
  • Can you mix RON95 with RON97?
Of course you can. The resulting concoction might taste awful, but you’ll still function.

  • Does RON97 clean engine?
However, unless your car manufacturer specifically tells you to use RON97, using this premium grade fuel will not actually rev up your car’s performance or give it a cleaner engine.9 Jan 2017
  • Can I use 97 octane petrol?
However, while it’s possible to mix these fuels, experts recommend sticking to the octane recommended for your car, whether 95 or 97/98, to ensure efficient performance and avoid engine damage.
  • Does fuel expire?
Once you’ve put fuel in a container you only have a few months before the quality starts to fall away – even less if the fuel is contaminated in any way. Generally speaking, petrol has a shelf-life of six months if stored in a sealed container at 20 degrees – or just three months if kept at 30 degrees

Common misconceptions

A higher RON or grade does not necessarily equate higher quality as most of you would have thought but rather its ability to delay auto ignition.

Another common misconception is that fuel efficiency or power output can be improved by using fuel of higher octane than that recommended by the engine manufacturer. If your car is not made to consume RON97, using RON97 will not increase its performance.
