Problems, problems, problems. " One bottle of ZddPlus contains more ZDDP than two bottles of GM’s EOS, which is no longer manufactured."

1) So what? You need less than 1 cup of EOS per oil change. More ZDDP is not better than enough ZDDP.

2) EOS is still being manufactured.

At $10 plus shipping and "handling" (?!) for a 4-ounce(!) bottle, this stuff seems like more hassle and expense than buying EOS.
