I was surfing the castrol edge pds/msds site because I was looking up the data sheets because I'm coming up on an oil change and was contemplating try the edge. Anyway, I came across these PDS, mosly dated NOV 2015 and they actually have a few real specs just not the minimums. I wonder when they will be released. Enjoy!
