Why does the car shake after an oil change?
2 Answers
The reasons for a car shaking after an oil change are: 1. The viscosity of the new oil is unsuitable or contains excessive impurities; 2. The oil level is either too high or too low; 3. Excessive carbon buildup in the engine, throttle valve, intake tract, or valve areas. Solutions for a car shaking after an oil change include: 1. Checking oil pressure and cleaning the fuel injectors; 2. Cleaning the throttle valve, fuel filter, and oil passages; 3. Inspecting and maintaining the engine; 4. Replacing with suitable oil. The method for changing oil is: 1. Lift the vehicle with a jack, locate and loosen the drain plug to drain the oil; 2. Remove the oil filter and place a container beneath it; 3. Install a new oil filter and add new oil.
My car has been shaking since the recent oil change. This is most likely caused by using the wrong oil grade or overfilling. The engine requires oil of a specific viscosity, and using a different grade may result in poor lubrication, leading to shaking. It could also be due to insufficient or excessive oil levels, so checking the dipstick is crucial. Air entering the system during the installation process, especially if the oil filter isn't tightened properly, can cause leaks and vibrations. Sometimes, after an oil change, the engine becomes more sensitive, revealing carbon buildup or idle instability. It's recommended to first check the oil condition. If everything seems normal, take the car to a repair shop for a comprehensive inspection of the ignition system. Don't underestimate this shaking; ignoring it can accelerate wear and even affect driving safety. Always choose oil according to the manual to avoid issues from self-replacement.
