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.

WebJul 7, 2024 · The fuel you burn in your car’s engine contains octane, C 8 H 18. When octane is burned, the products are CO 2 and H 2 O. Where is octane used? In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power. Such higher power comes from the fuel’s higher compression by … WebAnswer (1 of 3): Octane is just one of more than 100 different hydrocarbons that gasoline/petrol can contain. And octane itself -C8H18 - can have 18 different shapes (isomers) and they all react differently during combustion.

WebSep 11, 2024 · It could be one or more of the following things: too low a fuel octane, an insufficient cooling system, a poorly designed combustion chamber, too hot a spark plug, too much static compression, too ... 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. White porcelain showing no signs of carbon build-up, cracking, peppering, or oil deposits is considered an ideal spark plug after a run. ...
