Here's a question to all...
Does anyone here add ZPD to their oil if they are not running a synthenthic or diesel rated oil. I know in the last couple of years oil companys have changed the formulation of motor oil to meet the goverments new GF-4/SM requirements. Consequently many of the friction reducers have been removed like zink and phospherus, and well as a few others.

What are your thoughts?
