My concern is that Shell will dumb down Pennzoil and QS sites, in order to enhance their own line of oils. The Pennzoil site has never been in so much of a mess. I did find the Shell site where Penn was listed and the complete Product Data sheets info is missing or incomplete as in no ACEA data for several Penn oils. A sorry mess indeed. I think we need to keep a look at the Pennziol addivive packages to be sure they are not diluted in the future. Ed
