thanks for the info on evans, dusterb318. i looked into it and like you said,great stuff. narrowed it down to a local distributor and found out, it should only be used on engines that are new, which never had anything in it from the start. something happens to it if there is anything inside,like water or coolant. it disturbs the properties of it i guess. thanks again and fiqured you might be interested. oiiiiiio
