Is Car Shaking Related to Gasoline?
2 Answers
Car shaking is related to gasoline. Using gasoline with a lower octane rating can cause knocking, which leads to engine shaking. It is recommended that car owners remove the fuel tank and empty the gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained through distillation, cracking, or pyrolysis of petroleum. It is primarily used as fuel for spark-ignited internal combustion engines and mainly consists of organic compounds derived from crude oil distillation and various additives. The causes of car shaking include: 1. Low cylinder pressure: If one cylinder is not functioning properly, it can result in a misfire, leading to engine shaking. 2. Carbon deposits and oil sludge blockages: Over time, carbon deposits and oil sludge can accumulate in the throttle body, idle valve, and intake ports, causing blockages and restricted airflow. This affects idle stability and results in shaking.
I previously encountered an issue where my car was shaking for no apparent reason. At first, I thought the engine was broken, but after inspection, it turned out to be the gasoline causing the trouble. Once, I tried to save money by refueling at a small gas station, and the next day, the steering wheel was shaking like a phone in vibration mode. The mechanic said that low-quality gasoline contains more impurities, leading to incomplete combustion and uneven power output, especially noticeable during cold starts. Later, I switched to regular 95-octane gasoline and added a bottle of fuel system cleaner to flush the fuel lines. After two weeks, the shaking disappeared. Of course, there could be other possible causes, such as carbon buildup or aging spark plugs, but sudden shaking is mostly due to fuel quality issues. Now, I only refuel at reputable, large gas stations and never dare to save those few bucks again.
