Is it normal to have slight shaking after changing the engine oil?

Reasons for slight shaking after changing the engine oil: If the car still shakes after changing the engine oil, it may be due to excessive carbon deposits in the fuel system or a change in the grade or brand of the new engine oil. Here are the specific details: 1. Excessive carbon deposits in the fuel system: The fuel system is a delicate part of car components. It is recommended to go to a 4S shop for cleaning carbon deposits. Carbon deposits in this part are mostly concentrated in the fuel injector, combustion chamber, three-way catalyst, throttle valve, intake pipe, and combustion chamber. Cleaning carbon deposits in the fuel system is necessary not only to eliminate the shaking problem but also to avoid the risk of engine knocking and to provide effective data for various electronic sensors. 2. Change in the grade or brand of the engine oil: Engine oil in China is divided into two types: 5w-30 and 5w-40. Different types of engine oil are suitable for different regions. If you change to a different engine oil during car maintenance, slight shaking and increased engine noise may occur.

I just changed the engine oil, and the car is shaking a bit, which is quite common. The new oil needs some time to lubricate all the engine components, especially if the viscosity of the oil has changed—the engine will take a short while to adjust. It's like new shoes that are a bit stiff at first; they'll feel better after some use. But you should also check the oil dipstick to ensure the oil level isn't too high or too low, as that could also cause shaking. Additionally, when starting the engine for the first time after it has cooled down, the oil pressure may not be stable yet, leading to slight vibrations. Generally, driving a few kilometers or restarting the engine once or twice should resolve the issue. If the shaking is too severe or accompanied by unusual noises, it might indicate a problem, such as incorrect filling or an oil leak, and you should take it to a shop for inspection. Overall, minor shaking isn’t something to panic about—just keep an eye on it for a few days.

Last time I changed to new engine oil, I noticed a slight vibration at low RPM when driving out, which was quite concerning at first. Actually, this phenomenon is quite common because the new oil hasn't fully circulated yet, and the residual old oil has been cleaned out, so components need some time to break in. I've tried different brands of engine oil and found that higher viscosity oils tend to cause more noticeable shaking during startup. My solution is to take the car for a short drive, accelerating and decelerating a few times to distribute the oil evenly. Usually, it smooths out within ten minutes. Also, remember to double-check if the oil grade is correct - overfilling can put extra strain on the engine and cause abnormalities. If the vibration persists, don't delay for safety reasons and have it checked by a professional as soon as possible.

The engine shakes slightly after an oil change, which is not a big deal. It's mostly due to the new oil being in the adaptation period, causing uneven power output due to incomplete lubrication. If it only happens briefly during cold starts or at low speeds, it's fine; if it lasts longer or becomes noticeable, you should suspect issues with oil quantity, oil type, or installation. Quickly check yourself: pull out the dipstick to see if the oil level is between the marks, and start the car to listen for any abnormal sounds. Normally, driving for a while to let the oil warm up should resolve it, but don't take it lightly. If other symptoms appear, such as a sudden increase in fuel consumption, get it repaired immediately to avoid engine damage.

Slight engine shaking after adding new oil is quite common, mainly due to unstable oil pressure or residual air bubbles. After the engine is emptied internally, the new oil needs several circulation cycles to balance the pressure, which is more noticeable when the engine is cold. I recommend checking the filling amount—do not exceed the upper limit; also verify if the oil used meets the manufacturer's standards. If the shaking disappears after a few minutes of driving, it's normal; if it persists, check if the oil filter is installed backward or missing. During daily driving, start the engine a few times to let it warm up, and avoid stomping on the accelerator immediately. Generally, the issue will resolve itself, but if you notice excessively high oil temperature or black smoke, stop and inspect immediately for safety.
