Engine oil is the unsung hero in the complex ballet of an internal combustion engine, ensuring the efficient and seamless operation of all its numerous parts. But occasionally, both mechanics and auto fans may come upon a perplexing phenomenon known as “grey oil.” A greyish tint might be concerning since it may indicate potential problems in the engine of our cars, unlike the clear amber color we usually associate with good engine oil. In this piece, we examine the mystery surrounding grey oil, looking at its origins, how it affects engine efficiency, and providing advice on how to avoid it and fix it.
