Find a quality oil with Moly in it and just keep it changed at a reasonable interval. Use a UOA to determine the limit and change within it. That's all that is needed.

I do a ton of miles and keep my vehicles until the wheels fall off. I have never had a lubrication related failure, including timing chains even with high miles!

Delving into this some more, how can Moly prevent chain stretching? It's a anti-friction component.

I agree with the suggestions to run a good oil.
 
If we're talking about a DI engine then soot contamination is what ruins timing chains. Therefore frequent oil changes with quality oil are the best solution. It hurts to throw away perfectly good oil at 5k miles but, if it's soot contaminated, it's not perfectly good oil anymore.

TIMING CHAINS DO NOT "STRETCH" (metallurgically)

As each link WEARS - the overall length of the chain appears to "stretch"

Thanks. I can see how the word stretch is misapplied here then.
