My brother just grabbed 10 quarts/liters of Liquimoly Synthoil 0W40 at NAPA, on clearance, for $30. A great price for a good oil.
It’ll go in my Mercedes next year.

I'd buy it all at that price.
I put a can in my noisy 95 Wrangler 2.5L with 249k miles on it and found, over a couple hundred miles, the clatter quieted down. My concern was the old school engine on new oil. I have Valvoline Diesel Blue in it right now. Bought Rotella for the next change. 15W-40 weight.
I have noticed that the Liqui Moly mos2 has definitely quieted down the lady's 98 2.2 L Camry.
It has quieted my car down too. Though it is much more noticeable in the Camry.

If you buy this oil bcs. FCP deals, I would trust Pentosin (Fuchs) any day, every day over Liqui Moly.
Why would you not trust Liqui Moly? Did you have a negative experience with it, or just preference?

I haven't tried an additive since the BITOG autoRX, lube control and fuel power days (remember those? Lol), but did buy a 6 pack of liquimoly mos2 #2009 for my new to me 2019 Ram 1500 with hemi. Maybe we're talking different products, but 6 bottles shipped was like $32. I added a bottle along with Supertech synthetic 5w30 with my first oil change on the truck, right after I bought it with 15k miles on it.
My plan is to alternate mos2 with Lubegaurd Biotech on oil changes to boost moly in the oil to hopefully help keep any hemi valve train issues at Bay.
We'll see. With my usual $3 filter, it's a $24 oil change every 5-6k miles.

Yep. It is understadable and legit that the high import prices makes LM second choice for customers in the US. It is legit for people to complain about the high import prices of LM in the USA.
Nevertheless, it is a good, average, decent Quality oil. To me, it is on paar with Mobil, Castrol and Shell.
My impression ist that LM sometines get undeserved negative comments here at Bitog, while other brands that clearly have played games with customers and labeld group III as group IV - at lest here in germany - are praised and favoured. See how marketing works....
And: No. At this moment i dont use LM in my cars and bike. But i have used LM for a long time (20 years..) at the past and cant complain. And i never had problems with Oil consumption when using LM, and never heard of problems with Oil consumption when using LM from other people.

It is average oil, nothing more or less. Much better choices, regardless of price.

It is not the price. It is average oil, and not on par with many oils readily available, and definitely not on par with Mobil1, Castrol or Shell. It does not have anything to do with Groups (though Liqui Moly in 1990's was selling HC oils like they reinvented the wheel, and back then they were truly mediocre oil at best).
This sounds exactly like a Valvoline thread from 20 years ago.

Isn't Liquid Moly MoS2 basically Molybdenum Disulfide? That's a solid, I would never put that in my engine. If I want to add Moly to my motor oil there is always Lubeguard Bio/Tech that contains soluble Moly that will never ever drop out of suspension and if used per recommended dosage it adds 200ppm of Moly to your motor oil.
I dont know exactly the difference between the different types of Moly, but why dont you just trust the engineers at Liqui Moly? Dont you think that the guys at LM are aware about the risk that it could drop out of suspension?
Saying this, i have a air compressor in my garage, with a oil level glass gauge. I am using the LM moly additive in this Compressor. Despite that the Compressor is sitting soemtimes for months, the oil still looks dark, opaque, silver-shiny at the gauge glass after two years.
But, of course, some people have different expirences, as allways....
BTW, LM have differnet additives, some base on Moly, other on Bor or Tungsten.

Liqui Moly doesnt even use their own MoS2 additive in their own oils anymore, there was a time when the most of their oils had it (the 10w40 may still for old timers who have to have it because they used it years ago when it may have had some benefit) so what does that tell you

It tells me that MoS2 is such a high quality product
and so expensive that they decided to sell it separately as a stand alone additive instead of mixing it into their motor oils as the bottom line is very important 
Or maybe, just maybe, they figured out what a bad idea it is, however, they just couldn't say no to money
Because it's hard for a company to say no to money when it keeps rolling in. It is for the same reason that said companies don't make a concerned effort to educate their customer base. There is also no arguing with the customers, you either tell them what they want to hear and cater to their fantasies or they will move on. Don't try to tell them that they could damage their oil pump or clog up an oil passage with MoS2, they don't want to hear that. Best case scenario that crud winds up in the oil filter.

They still offer one oil with Moly allready in it, at least in their product range here in germany.
Exactly. I've used the MoS2 as well as Ceratec in my VW...no issues and as you say, if this was known to cause drama, you'd have heard about it. I'm quite sure the R&D folks at LM have thought of all of this. Someone here posted a pic in the additive sub-forum I believe that showed that it had fallen out of suspension...ok...so when you start it up and the oil pump pumps it around it get mixed. Why not sell it for $5 a can and make that extra money? That's good business, not nefarious...I wonder if it's simply an approval thing w/r to why they don't include it in their oils (I think they still have one 10W40? that contains it?). I use the Molygen currently and that has the Tungsten in it so no need to add anything else if friction modifiers are your thing.
LM does a great job on the info front. Live tech chats on IG, easy email with immediate responses, easy to use website etc. Not sure how that is an issue with them? I guess b/c you don't like LM? A can of MoS2 is about $5 online...hardly an expensive additive if you use them. My take is they don't offer it in many of their oils b/c the approvals won't allow it - here is their only oil with MoS2...old-school 10W40:It tells me that MoS2 is such a high quality product
