fivepointohman Posted April 2, 2008 Report Share Posted April 2, 2008 Changed my plugs today. they had about 30K on them with hard driving on a 122K motor... Car had plenty of power, Just changed them cause the car has been sittting for 6 months and I am taking it from NY to SC next week. Changed the wires as well. The plugs were factor 41-950 AC delco Platinums. The old plugs had alot of white deposits on them, almost like a corroded or ashed up look. I know the previous owner ( my friend ) used a crap load of Fuel cleaners and additives, which I know leaves this deposit behind. I been using 89 in this car, should I go higher to keep the engine and head gaskets happy? I was concered about collant being burned and that being the deposits. But I dont think that is the case I think. Just askin everyone opinion. Link to comment Share on other sites More sharing options...
