Been since the early 70's since I had any

of them that our dealer customers had doing their own oil changes.I never bought them due to that.Was just wondering if this is a good buy or not,looks like it is so I may bid on them as no one has yet,thanks guys.Also when I was a maintenance manager for a developer in the late 70's the former guy was using Delco for all of the units and the Fords would rattle the same.Changed to Motor Craft and problem went away.Times change a lot of things but I guess I never had a reason to look into it as a Ford guy I like O.E.M. when possible.JMO of course.
