Anyone using Molylube additive with oil changes?

Several here do, and I have before. IMO, you cannot prove it's useless, so adding it also cannot hurt. Unless you can't afford it then do what you want.

Many types of moly, but they fall into two categories for additives, moly in suspension and oil soluble moly. I think the auto manufacturers and oil manufacturers don't believe it is snake oil because the oil soluble stuff is in almost all engine oils. With the newest engine oil specs EP additives will be even more common and likely a requirement to get an api label, coming soon with the movement down in viscosity. I'm not sure what this is, maybe post a link. Moly in suspension additives are an unnecessary risk when they have oil soluble moly as in lubegard. Which is why every single oil manufacturer uses oil soluble moly and not powdered moly, even liqui moly doesn't used powdered moly in their oils, just in their additives. It is old tech, this mousetrap was improved.

If it's already in the oil, why add more?

The same way you can't prove that it does any good. ;)

Well, one itsy bitsy tiny type reason is because the gov't through the CAFE standards have forced p!zz thin oil on engines running 400 pony's with next to no protective additives that oils had in 2002 before they forced low ep/aw additives on us, which has led to horrific engine failures and lack of cam/lifter protection, now with "resource" saving even plummeting the protective additive in engines oils that might be one little itty bitty type of reason to want just a hair of a itsy bitty more protection.

One question, was that a run on sentence?

Exactly, that's why I said "it also cannot hurt" ... anything but your pocket book.

hence some thinks it helps, other don't, no way to settle the issue across the board.

Some may be trying to up the content to match a redline oil... redline has been proven to quiet the hemi tick. Been running redline since 16k miles, engines still quiet. I change the oil every 2k...

My neighbor, same year, hemi, same mileage, has been doing oil changes every 6-8k miles, 5w20 recommended oil, whatever deal he can get at the auto parts store, and there's a clear difference between the two motors. He had his exhaust manifold replaced already, I haven't (not related, I know).

Tons of research out there to support what moly does to protect parts. Lots of real world stories on this forum too.

How did you determine the product is “Great stuff”?

Ram does not recommend an engine oil additive. Why add one?
Being a hemi tick survivor and not running redline as wasn't a lot of knowledge on what oil to use 5 years ago. I went with Castrol. I am at 140k and it started a hair harder then I wanted and was a little noisy. Since adding it no change in motor pressure oil psi or temp. It is significantly quieter. Well it was until I did my muffler delete. I am not out to push anything. I only give my opinion on things that have worked with my truck specifically. Yes dodge doesnt call for additives, but it has been a good extra line of protection. Just my .02.

I add nothing to my oils.Never had never will. I like to keep it as simple as it's to say my Hemi only gets Castrol 5w30 with Mopar oil filters every 7-9k miles. 107k miles currently. Zero issues.

I've put Molylube with break-in oil after rebuilding an engine and putting in a new cam and lifters. However I change oil after 500 miles and don't put it in again. I've read where it can damage the catalytic converters.

I mixed the Molybdenum into the Aeroshell 5 grease for the landing gear actuators for Mooney aircraft. Faa required 10% moly by volume. I don't know if it did anything.
