I'm trying Tungsten disulphide powder, currently added to commercial Purple Extreme lubricant. Friction is one thing but wear is another (though probably linked). It looks dirty but seems ok.Have you considered/tried adding boron nitride (e.g. the key ingredient in some finish line products), graphite powder (readily available) or even molybdenum disulphide
I don't know how to do an objective test to see if my chains last longer. Practically in muddy conditions my chains stay quiet longer then my fellow riders, but then Purple Extreme seems to be quite a good lube anyway.
With chains at $25 from CRC and lube at $15 it questions how much effort you should spend making your chain last.
