I wait until the Valvoline semi synthetic is on special at supercheap, and buy a big bottle at a time.
The link that you just posted makes sense.
I've read papers that indicate that friction modifiers in fuel make it to the region of the oil film around the top ring also, so may genuinely provide Upper Cylinder Lubrication.
