        "summary": "Mixing Pertamax and Pertalite can lower combustion quality and reduce engine performance. Experts advise using fuel as recommended by the manufacturer (minimum RON 92) to minimise carbonation deposits and avoid knocking; mixing fuels is discouraged.",
        "content": "<p>SOLO, KOMPAS.com \u2014 Mixing two grades of petrol with different quality\nlevels, such as Pertamax and Pertalite, is commonly done by motorists in\na bid to obtain better-quality fuel at an affordable price.<\/p>\n<p>In fact, Pertamax and Pertalite are types of petrol produced by\nPertamina, with different price points, characteristics and quality.<\/p>\n<p>Pertamax has an octane rating (RON) of 92, slightly higher than\nPertalite at RON 90. This difference affects the power produced by the\nengine.<\/p>\n<p>\u201cIf mixed 50\/50, it becomes RON 91, and neither petrol would meet its\nrespective standard. As a result, combustion quality declines and engine\nperformance can be affected,\u201d Jayan told KOMPAS.com recently.<\/p>\n<p>If a driver normally uses Pertalite, their vehicle\u2019s engine\nperformance is better. Conversely, if a driver normally uses Pertamax,\nthe mixed fuel would be detrimental.<\/p>\n<p>\u201cIf mixed, the formulation will be disrupted, resulting in more\ncarbon deposits, which affects the combustion engine\u2019s performance, so\nit is not recommended,\u201d Tri told KOMPAS.com recently.<\/p>\n<p>Hardi Wibowo, owner of a Nissan-Honda specialist workshop in\nYogyakarta, said the reduced performance of the Pertamax-Pertalite mix\nis due to the residues produced.<\/p>\n<p>Hardi said the data were obtained from observations of modern cars\nundergoing routine maintenance every six months at his workshop.<\/p>\n<p>\u201cWe advise always using petrol as recommended by the manufacturer, at\nleast RON 92; when below that, including if mixed, there is potential\nfor reduced performance, such as knocking and the combustion chamber\ngetting dirty quickly,\u201d Hardi said.<\/p>\n<p>\u201cPetrol with a low RON tends to ignite on its own; this triggers\nknocking and the power produced becomes suboptimal, and it also makes\nthe car require more frequent cleaning or maintenance,\u201d Hardi added.<\/p>\n<p>Thus, consumers are not advised to mix two different petrol types, as\nPertalite\u2019s properties will influence Pertamax, which better aligns with\nmanufacturer recommendations.<\/p>",
