I took my spark plugs out to check them today and they looked good mechanically, but were covered in a fine red dusting. Iv'e never seen this before, and it's not on any spark color chart I can find. Anybody heard or seen of this?
Maybe you guys are using the same brand of gas?well i just replaced my plugs with iridiums they was only $6.35 at advanced auto. when i pulled my plugs they had the same red dust coating as well???
my tank is spotless no rust anywhere??? mabie its somthing they r putting in the fuel now? i run 87 oct and havent added anything
