As shown below, a buildup of combustion deposits stems primarily from the burning of oil and/or fuel addatives during normal combustion.
These are normally nonconductive. However, when heavier deposits are allowed to accumulate over long mileage periods, they can "mask" the spark, resulting in a plug misfire condition.
