What causes engine knocking?

Engine knocking is an undesirable sound that your engine can make when the air-fuel mixture in the cylinders is detonating in more than once place at a time. The cause of engine knocking is a lack of octane in the fuel.

Detonation is a very rapid combustion of the fuel-air mixture in the engine. When this occurs, the air-fuel mixture can "knock" against the sides of the piston, causing a knocking noise.

The higher the compression ratio of the engine, the more severe the engine knocking will be. A high compression ratio is when the piston is forced down into the cylinder more than once on the power stroke. This is what causes the air-fuel mixture to be squeezed together so tightly that it can easily detonate.

The best way to prevent engine knocking is to use a fuel with a higher octane rating than what is specified by your vehicle’s manufacturer. You can check the octane rating of your fuel by looking for the "octane rating" on the pump at your local gas station.

If you are experiencing engine knocking, you can try adding a fuel additive to your fuel tank that is designed to reduce engine knocking. You can also try slowing down your driving habits.

In some cases, adding oil can also help to improve the fuel economy of the car. This is because the oil can help to reduce friction between the moving parts of the engine.

It is important to note that not all oils are created equal. Some oils are better at reducing engine knock than others. It is important to choose an oil that is specifically designed for knocking engines.

Overall, adding oil can help to reduce engine knock in most cases. However, it is important to choose the right oil and to make sure that the engine knock is not too severe.
