Believe it or not and I may be wrong, but for the U.S market I think that "Full synthetics" only have to be %30-%40 synthetic in order to be call "full synthetic." Sythetic most definatly helps fight against coking. I have had the best luck with Amsoil. Non-synthetics most certainly break down easier than "real synthetics"
