Spark Plugs White
I changed out my spark plugs last night.....or at least started to. This will take me longer than most, but that's ok. I began with the driver's side and got them done. I noticed all the ones on that side are white, glazed white at the tip. Why? Research says that it is caused by additives. Could Ethanol be doing this? I don't use it, but maybe the last guy did? I can see why it was misfiring so. Scott
P.S. I don't think Seafoam would do that, would it?
