Many vehicle owners assume that using petrol with a higher octane\nrating, or Research Octane Number (RON), will make fuel consumption more\nefficient. This assumption is not entirely wrong, but it does not apply\nto all types of vehicles. In reality, the level of fuel efficiency is\nnot solely determined by a higher RON, but by the compatibility between\nthe fuel type and the vehicle\u2019s engine specifications. If the fuel used\nmatches the engine\u2019s compression ratio, the combustion process will be\nmore optimal, allowing fuel consumption to become more efficient.<\/p>\n
RON is a measure that indicates a fuel\u2019s ability to withstand high\npressure and temperature in the combustion chamber before igniting from\nthe spark plug. The higher the RON, the greater the fuel\u2019s resistance to\ncompression pressure. This results in more stable combustion and reduces\nthe risk of detonation or knocking, especially in engines with a high\ncompression ratio. In Indonesia, petrol is available in several RON\noptions, ranging from RON 89 and RON 90 such as Pertalite, to RON 92\nlike Pertamax, and up to RON 95, RON 98, and RON 100. Each is designed\nto meet the needs of engines with different characteristics.<\/p>\n
Petrol with a higher octane rating can indeed make fuel consumption\nmore economical. However, this is only true if the fuel type used\nmatches the vehicle\u2019s engine compression ratio. In engines specifically\ndesigned to use high RON, such as RON 92 or RON 95, combustion will be\nmore complete and stable. This condition produces more optimal power, so\nthe engine does not have to work as hard to deliver the same\nperformance. This combustion efficiency can ultimately help reduce fuel\nconsumption, making the vehicle feel more economical compared to using\nfuel with a lower octane rating than the manufacturer\u2019s\nrecommendation.<\/p>\n
Every vehicle engine is designed with a different compression ratio.\nThe compression ratio is the comparison of the combustion chamber volume\nbefore and after the piston completes its compression stroke. The higher\nthe engine\u2019s compression ratio, the greater the pressure the fuel\nreceives in the combustion chamber. Therefore, high-compression engines\nrequire high-octane fuel to prevent premature combustion or knocking.\nConversely, low-compression engines do not require high-octane fuel. The\nkey is not using the highest RON, but using the RON that matches the\nvehicle\u2019s specifications. Information regarding the recommended RON can\nusually be found in the vehicle\u2019s owner\u2019s manual or official\nmanufacturer guidelines.<\/p>\n
As a general guide, RON selection can be adjusted to the engine\u2019s\ncompression ratio: engines with a compression ratio of 9:1 to 10:1 are\ngenerally suitable for RON 90; a ratio of 10:1 to 11:1 typically\nrecommends RON 92; and a ratio above 11:1 is more suited to RON 95 or\nhigher. However, this guidance is general. Each vehicle manufacturer may\nhave different engine specifications, so the official manufacturer\u2019s\nrecommendation remains the primary reference for choosing fuel.<\/p>\n
Beyond the RON, fuel consumption is also influenced by various other\nfactors, including engine condition and maintenance, tyre pressure,\nvehicle load, driving style, traffic conditions, use of air\nconditioning, and fuel quality. This means that using high-octane petrol\nalone is not enough to make a vehicle more fuel-efficient if these other\nfactors are neglected.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/is-high-ron-petrol-more-fuel-efficient-an-explanation-based-on-engine-compatibility-1784775203", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
