In order to avoid flying sparks and electric shorts, ONLY use the GM special grease (non electrically conducting) for the ignition coils. The usage of other grease could result in a fatal electric shock, fire and severe damage to the vehicle.
The grease tube could be used for at least 25-30 vehicle engines. This should avoid that too much grease is used for a single spark plug. Too much grease could influence the ignition behavior.
