Never had any problems.

came across this the other day, seems relevant to this thread.
F1 lubrication - Forum - F1technical.net
lubromoly/petromoly
i've never heard of it and i've seen a LOT of oil additives before, almost all of which were based on junk "science". it appears that this may or may not have a basis of fact.

As a note, I was into mpg(a little bit) just didn't a-b-a test things back then. My " recollection" is that I got better mileage.

i guess i'll share:
i've used slick50..... once..... pretty sure it did nothing but thin out my wallet.
anyways, did more research on the lubromoly/petromoly, turns out some of the BITOG guys have also played with it, reports of 3% gains seem to be the norm, even when used in oils that already have decent amounts of moly in them.
looks to cost about $9/quart at most stores. most seem to use a "full" dose once, then half doses afterwards to keep the level of moly in the oil after a change high enough to have an effect.
at a 3% gain at 30MPG, that's 30.9MPG. assuming a 5,000 mile oil change interval, you'll burn through 161.81 gallons of gas instead of 166.67 gallons, a difference of 4.86 gallons. assuming $3.50/gallon, that's $17.01 of fuel saved by spending $9 on an oil additive. that's for the initial dose. "maintenance" doses, $17.01 by spending $4.50.
and if you run oil changes longer than that, you'll save more.
so, pretty small number, but interesting to see something having a benefit.

As the msds link I posted shows, zmax and slick50 are entirely/almost entirely mineral oil. If it does work you could save yourself some money.

Not since the 80s.
I tried it for a couple of changes in an older car and didn't note any of the so-called "improvements." Fuel mileage stayed the same, engine sounded the same, no perceptible change in power output. My assessment then was about what it is now: snake oil.
Hmm. I wonder if you could render oil from snakes. Would it do better?

I've never read any real world praise about it or the like.
I do run Lucas oil stabilizer in my high mile rig's. The motors run smoother and quieter, with quieter cold start's. As far as helping EF, I can't say other then a smoother running engine is going to be more efficient.

Moly seems to be legitimate. It's not pushed by one specific company as an additive. There are oils that use high amounts of moly for it's benefits.
