Z-ALT Muscle Car Oil
Have any of you guys heard of this oil or used it? I first saw an ad for it in the current, Jan., 2010, issue of Hemmings Muscle Machines. It sounds great if everything it says is true. It would save having to add ZDDP additive to a current regular motor oil. I'm thinking of using it in my '69 Z when it comes time for an oil change. Any opinions much appreciated.
