I'm not one to log mpgs anymore, unless we're going on a road trip. My best experience with MoS2 is it stopped an old mower I acquired from blowing smoke [oil]. It needed a carb rebuild and a plug to get it running. MoS2 completely stopped the smoke issue for a few years now.

I have a feeling the MoS2 "plating" fills tiny imperfections in the cylinder wall similar to Restore, only not as well.

I didn't manual log the fuel mileage, the car has trip computer. I changed oil and reset it so it will start counting down from 10k miles.

I owned the car for 14 years, I read the trip computer once every few thousands miles. It is very accurate compares with manual calculation, the error is less than 2%.

I was a little surprise to see the gas mileage improvement in less than 200-300 miles of adding MoS2.

Another observation, before the oil change there was a small oil leak about 5-15 drops on a cardboard on garage floor very day. The valve cover gasket is original and looked wet. Since adding MoS2 with new oil the leak seems to stop, the cardboard is clean without any oil drop. The engine seems to run a little quieter too.

I'm going to change oil in the S2000 soon, will add 1/4 bottle MoS2 to 5.1 quart capacity.

So far there is no negative effect from the Lubro Moly MoS2 I can detect. There are some snake oils from some questionable companies, and there are some good additives from reputable companies. Lubro/Liqui Moly and Lubegard are 2 of some reputable companies I trusted.

Read a very interesting piece of info on Mos2 that is quite precise and proven. www.theparsecgroup.com/experts.htm After reading this I was sold; ten times over. This is one product in its own class.

Right, its 'own class'. As the most popular industrial lubricant in use today, it deserves its own class. As a motor oil additive that has been in public use for at least 60 years, it deserves its own class. There is no serious debate about the usefulness of MoS2. The only place where its usefulness is debated at all is... BITOG, invariably by people who have never used it. Seriously.

There are several SAE studies cited in your link, as well as university studies of MoS2 - mostly flattering. If you go the the Society of Automobile Engineers website and use their search engine, you will discover that molybdenum in various forms has been very widely studied for a very long time. Studies of other additives like PEA or ZDDP are also studied, but not necessarily in the same numbers.

Don't expect to change many BITOG minds with your posting. Independent studies and research on MoS2 usually have to do with the underlying chemical compound. Brand-name applications of MoS2 (e.g. Molykote or Liqui Moly MoS2) are not independently studied. But brand-name applications of any additive product are never independently studied, for a variety of practical and legal reasons. End products may be studied by the product manufacturer, but manufacturers don't release detailed results of their internal studies. Does anyone think Volkswagen would market or distribute MoS2 under their own name without studying the product? But don't hold you breath waiting for VW to release the results of their research.

BITOG discussion of MoS2 (maybe other additives as well) frequently devolves into two camps: respondents who have used a product, or are considering using it, and are seeking or sharing information. Then there are those who have never used a product but are able to form an opinion that they don't like the product. Take your pick.

In the information sharing department, Parsec Group seems to market several MoS2 related products (Spica Blue, Spica Gold, etc). Spica Blue, a gasoline additive, seems to be registered with the EPA. Has anyone ever seen or used any of their products?

I finally found some solid friction-reduction data!!!! http://www.infineum.com/sitecollectiondocuments/notebooks/gf5/ResearchReport.pdf
page 23, where a variety of different types of gasoline car engines were tested in quality engineering labs for friction reduction (fuel economy increases), where the only thing different was one oil had 1000 ppm moly in it. .... I have been using Mazda's 0w-20 high-moly 600 ppm latest SN oil, and I think they are on to something using that high amount. Now I also feel more confident in buying and using LiquiMoly MOS2 additive. .... Test results show a 0.5% to 3% improvement, depending on the engine you use it in. Thats big.

Thanks for posting this. Moly is good stuff, IMHO. At 600ppm, the folks at Mazda must agree. That's almost twice the moly content of Schaeffer's Supreme motor oil (and the Schaeffer folks are really into moly).

I wonder if Mazda likes it for lubricating their Wankel engines?

That paper I linked to, on page 20, also shows why Mazda (Idemitsu-sourced 0w-20 oil) claims on their oil bottles that the high-moly oil starts working to reduce friction at lower temperatures. The chart shows a couple of high moly oils beginning to work as low as 50 degC, while other oils without moly don't do much until about 90 degC or so. .... (I learned a while back that Japanese companies rarely make false marketing claims since their culture doesn't allow for losing-face much.)

The trip computer in my E430 showed 19.3-19.8 MPG with average speed of 29 MPH over more than 20-25k miles. The trip computer was reset at every 4-5k miles. For some interval when average speed was 28 MPH over 4-5k miles, the gas mileage went down to 18.2-18.5 MPG, with average speed of 27 MPH it went down further to mid 17.xx MPG.

With MoS2 the gas mileage is 20.3-20.5 MPG with the same average speed of 29 MPH. I only used 1/2 bottle in 8 quarts sump.

I think Liqui Moly MoS2 is worth $5-6 a bottle. Especially when you use 1/2 bottle for initial treatment and 1/4 bottle maintenance at every oil change. The money saved in lower gas used in an OCI is more than pay for a bottle of MoS2.

I ran 1/2 bottle of Liquimoly MOS2 additive, with Rotella T5 oil, T5 doesn't have any extra moly in its additive package, ran it 4,000 miles. The crankcase capacity is 2 gallons, I should almost be running 2x300ml bottles of mos2 additive with the crankcase capacity. Jeep Grand Cherokee EcoDiesel.

Realistically I could've ran Rotella T6 or Mobil1 TDT and it would've had nearly 100ppm MOS2 without any extra additive.

Also another company sells similar additive, Mr. Moly, or Molyslip in Canada.

Your not using enough. Use as directed for best results,or for any results at all

I'll use as much as I want, when I want, thanks!

and btw, I see many in here are speculative of MOS2/Molybdenum, its a fairly common additive in few oils, Pennzoil yellow bottle has around 200ppm, Redline packs in the MOS2, 600+ppm!

Then don't expect much, if anything.

See. There are these guys at a company called liqui-moly,and they do these things called tests with their products.
Then they take that data and devise a set of instructions when using their products so the user can get the results the company claims.
So personally I really couldn't care less if yup light money on fire,or let the stuff collect dust,that's entirely up to you,I merely pointed our that by not following the instructions you will not achieve the desired results.
Mos2 is not organic moly,nor tri-nuclear moly,so your link doesn't mean much comparing its use and how many ppm of moly contained.
The tri-nuclear type used by shell and Mobil is far more effective than the organic type and therefore needs much less.
And if you spent a bit of time reading about mos2 instead of posting with an attitude you'd be aware that organic moly and mos2 don't work in the same manner,and therefore comparing them is like apples and oranges.
But carry on. And keep posting. I find it amusing.

Hey, VW is using it so at least we know something positive is gained. Even at its worst its still better than putting something like hyperlube/lucas oil in the crankcase. I have had no issues with LM mos2 and will keep using 150ml in a 3.3 qt sump. I havent seen the gains I wanted, but when I switch from 5w30 PU to 5w20 in the winter this product does marvels to startup and mpg. I have read too many ppls feedback to doubt its use but I had to try it myself and have always had positive results. I think it can be said that products that work remain whilst others go away.
