Honda OEM requires a "detergent oil" to be used in my 2001 Accord. Want to switch to Quaker State Ultimate Durability (on sale at Wallmart). Since most oils have detergent additives, is it safe to say Quaker State Ultimate Durability has a detergent add-pack as well? I think it might be an API requirement anyway. In either case, Quaker State Ultimate Durability packaging dosen't say anything about it's cleaning ability (like PP). Thoughts?
