The best way to describe car engine knocking is an annoying pinging sound which comes from the engine area. There are lots of reasons as to why there would be engine knocking. Perhaps there is an imbalance in the air to fuel mixture, resulting in the gas burning unevenly. Another reason for engine knocking is an inadequate amount of lubrication in the engine, particularly around the upper cylinder head. If the lifters and valves of this area are not properly lubricated with good strong oil, then it causes a pinging or ticking sound to be heard.

If you have an older engine, then the risk of engine knocking increases even more. Older engines tend to have more issues when it comes to lubrication. Even if you use synthetic oils to help expand their longevity, it still might not be good enough for an old engine which has rusted or corroded parts. To fix this problem, there are special oil additives that you can add to your engine oil to help clear away this rust and corrosion. Once you do that, you might find the oil will flow smoothly again in the engine. As a result, there won’t be so much knocking or pinging anymore.
