What to do if the car engine is knocking?

When the knocking is slight, the engine power is slightly unstable, the engine shakes severely, and it will cause the engine to overheat and emit black smoke. The solutions for car engine knocking are as follows: 1. After the engine starts, if there is a knocking sound during low-temperature operation, and the sound disappears when the temperature returns to normal, it can be left untreated temporarily and continue to run. 2. When the engine temperature is normal, if there is an obvious knocking sound, high-speed operation should be avoided as much as possible, and the engine should be disassembled and repaired as soon as possible. 3. If the cylinder is severely out-of-round, scratched, or the gap between the piston and the cylinder is too large, it should be replaced. 4. If the connecting rod is found to be deformed, it should be replaced as much as possible.

How Long Does a Subaru Boxer Engine Last?

Subaru boxer engines generally last between 200,000 to 300,000 kilometers. More information about Subaru boxer engines is as follows: 1. The Subaru boxer engine can enhance performance on paved roads and also improve driving capability in adverse road conditions. When controlling drive on stable road surfaces, the flexible utilization of the motor's powerful torque and responsive sensitivity further enhances passability in challenging road conditions. 2. In vehicle configurations equipped with this engine, the addition of a rear support auxiliary frame increases the torsional rigidity of the wheels and the rigidity of the rear suspension auxiliary frame mounting points. This achieves performance equivalent to gasoline vehicles in all aspects, including handling stability, vibration and noise performance, and ride comfort.

When Should Fuel Additives Be Added?

Fuel additives are generally added every 10,000 kilometers. Here is the relevant introduction: 1. Engine carbon deposits can gradually accumulate inside the engine unnoticed. If carbon deposits are ignored, they can slowly reduce engine power, lower fuel efficiency, worsen emissions, and lead to a series of engine malfunctions. 2. The fuel system can remove carbon deposits, enhance power, save fuel, reduce noise, and prevent engine failures caused by fuel issues. 3. Automotive maintenance chemicals clean the fuel system, stabilize fuel, reduce carbon deposits, and protect the engine. However, the current market for fuel additives is mixed with varying quality. Under normal circumstances, it is recommended to use OEM (Original Equipment Manufacturer) additives, typically adding them once every 10,000 kilometers is sufficient.
