Thank you tango for the list. I see the info is from 1991. I'm new to this and Im not advertising for any body Cobalt327. Here is the link to Archer oil. www.archeroil.com
. If you go to their products page you will find lubricants listed by categories. Then click on the category you are checking and then click on the spec sheets for that product. I dont want any one going on a shipe hunt for the info.
