In the latest Action News letter, there is an article about how the industry is forcing oil companies to reduce anti-wear addivies to improve emissions, something we are all aware of. In the article, it said due to the reduced level of anti-wear additives, oils are not lasting as long. They went on to say Amsoil is testing new formulations to stay ahead of the curve. Ahead of the curve? Isn't Mobil 1 SuperSyn the answer to this along with GC and others? It's going to be interesting to see if Amsoil reduces ZDDP any lower. And if they do, what replaces it. In a few months, Redline and Synergyn might be the only two oils left with hefty amounts of ZDDP.
