Is Car Shaking Related to Gasoline?
3 Answers
Engine shaking is related to gasoline. Using low-octane gasoline can cause knocking, which leads to engine shaking. The engine is the device that provides power to the car, converting the thermal energy of gasoline and diesel into mechanical energy by burning the expanding gas in a sealed cylinder to push the piston and perform work. Its components are as follows: 1. Valve train. 2. Crank linkage mechanism. 3. Ignition system. 4. Cooling system. 5. Lubrication system. 6. Starting system. 7. Supply system. The engine maintenance methods are as follows: 1. Use qualified engine oil. 2. Use qualified coolant and antifreeze. 3. Regularly clean the radiator scale. 4. Regularly clean engine carbon deposits. 5. Regularly replace the car's three filters. 6. Maintain a reasonable speed.
After driving for ten years, I've found that car shaking is indeed closely related to gasoline. It was most noticeable when I filled up at a cheap gas station—it felt like sitting on a massage chair while driving. Later, switching to a reputable gas station made a big difference. Low-quality fuel contains more impurities and burns incompletely, which naturally makes the engine act up. When the fuel pump pressure is unstable, there's also rhythmic shaking—lightly pressing the accelerator feels like going over speed bumps. The worst is when the fuel injectors get clogged; during sudden acceleration, it shakes like the car is about to fall apart. Once, there was water in the fuel, and the car shook so much during a cold start that the rearview mirror was vibrating. Now, I consistently use 95-octane fuel along with fuel additives, and idle shaking hasn't been an issue since. Everyone really should choose reputable gas stations when refueling.
From the perspective of engine principles, car shaking is absolutely related to gasoline. Low octane gasoline can cause knocking, and the shaking accompanied by that rattling sound is most harmful to the engine. When fuel line blockage leads to an overly lean air-fuel mixture, even the tachometer needle will dance. I once disassembled and cleaned the fuel pump filter screen, and the amount of gum deposits inside was shocking—no wonder the car would gasp when accelerating. If there's water in the fuel tank, the engine will jerk intermittently like an asthma patient during acceleration. It's recommended to clean the fuel system every 20,000 kilometers and choose major fuel brands. Of course, shaking could also come from worn engine mounts, but it's wiser to rule out fuel quality issues first.
