Burning octane in a car engine

WebJul 25, 2011 · I've heard from some people that high octane fuel will increase gas mileage. Around here, we have the basic unleaded (87), mid-grade (89), and premium (93 or 91). I've been using the basic 87 unleaded forever because it was the cheapest. Also, in my car's manual it recommend the lowest grade to use is 87 (Grand Am 2004 V6) WebNov 28, 2016 · This is important for internal combustion engines because in order to create an explosive charge in the cylinder, the engine must compress the fuel-air mixture quite a bit. While octane handles this pressure quite well, heptane tends to detonate prematurely. This phenomenon is called knock and can severely damage the engine.

WebA typical engine might have a compression ratio of 8-to-1. (See How Car Engines Work for details.) The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. WebJan 8, 2024 · Engines that run hotter due to lower-octane gasoline may burn off more residuals in some cases, whereas more residuals may build-up from an engine using higher octane fuels.

WebA high compression engine can derive more energy from the combustion process, but gasoline heats up the more it’s compressed. Since the fuel pressure is higher in forced induction and high compression engines, the gas tends to combust at the wrong time. Hence, such engines require high-octane fuel to avoid spontaneous combustion.

Web"Higher octane" only means more knock-resistant. It does not mean "harder-to-ignite" or "hotter burning." A gasoline engine will not perform worse in any way on higher-octane gasoline. The higher-octane outputs of a gasoline refinery have only been reformed to be more knock-resistant. WebNov 4, 2024 · Regular fuel is 87 octane. Premium is 91 or 93. Midgrade falls somewhere in the middle, often 89. To understand what octane means, we first have to look at the concept of preignition.
