Anyone know the ZDDP content of the new GM EOS?
I found the lab results for the old stuff, impressive. Supposedly the new formula has less, just wondering how much? I changed my oil with SL oil and added this as well. Second oil change, dark and thin, was SL 5W30. I went 10W40 this time. Pulled a plug, looked good and adjusted the choke pull off, was too rich.

It seems GM's supplier wouldn't make it to their spec. The new stuff contains the same ZDDP as before, just mor Calcium, a detergent. I can get it for $8 locally. Finally found it on a Turbo Buick site. https://www.google.ca/url?sa=t&sourc...g2bAIuclr-CJLA
