As the airhead forum moderator on the BMWMOA forum has a call out for new oil analysis info, it's obviously not easy info to come by? How/where are you guys getting the ZDDP content for the various oils mentioned here. It seems like a no brainer to use the cheapest dino oil in the correct weight & also containing adequate zinc. So, where do you go for these figures mentioned?
FWIW, in my oilhead I use Syn Rotella T-6.
