A spark plug is one of the most crucial components of the engine that ignites the air-fuel mixture within the engine’s cylinders, setting off the controlled explosion that drives the engine’s pistons and ultimately propels your car forward.
But when there is oil comes over the spark plugs, it becomes less efficient and disrupts your vehicle’s performance
In this blog, we’ll explore the symptoms and causes of oil on spark plugs

The presence of oil on your spark plugs is not an immediate cause for alarm, and you can still drive your car with this issue. However, it’s essential to understand that the real concern lies in how the oil ended up on the spark plugs.
If the oil is limited to the spark plug thread or tip, your car’s engine can typically burn it away without major issues. However, if oil persists in the spark plug threads or plug wells over an extended period, it becomes a significant problem.
