I've never tried this stuff before, but my local ACO hardware had this on sale for $3.49 a qt. Says it meets the SM service code. Thought for the price what the heck. Anyone have opinions or experience with this stuff?
I do believe it was owned by Pennzoil, now SOPUS has all the QS Pennz under one tent, and they regarded Wolf's Head as "not important" to the overall product lines. Amalie wanted the name to bring it back so they happily bought it from SOPUS, who happily sold it.
That's the story I heard.
