The moly looks kind of like Grease, but, oh, what a smoooooooth engine you have, on even -half- a can!

FWIW, i ended up putting the "Whole can" in 500 miles later, after adding half the can. I ended up having Oil that looked like a blown Head Gasket. Makes me wonder if my Head Gasket IS OK, or if its a leak Stop-Leaks can take care of.

In any case, Moly WILL help, as its a "Plater" and would help plate the gasket area there.

It would depend on the particle size of the moly. If it is too large the filter will stop it from circulating in your engine.



The particles are too small for even the most efficient filter to trap.

Anyone here using this additive along with a bypass oil filter (like an Amsoil EaBP-90)? I'm wondering if the bypass will filter out a significant portion of the additive...

(edit: Spyder- just read your post after I posted. d'oh!) I'm wondering if anyone has cut up a filter to check, though...

Mine will be cut open once its run its duty cycle (should be around Spring time), meantime my previous statement was based on the particle sizes this filter can trap compared to the published particle size for the average moly particle in mos2 (the gap between the two is by a very substantial margin).

How many average sized particles would have to conglomerate before they would be caught by the filter? In other words, how many times larger is the minimum filtering size of the filter than the average size of the moly particles?

LOL, I was thinking "aggregate", but typed "conglomerate".

1. Amsoil Eabp90- 98.7% @ 2 microns
2. LM mos2-

So can we assume that clumps of LM mos2 particles > 4 particles will be caught in the Amsoil filter?

 

[Spyder7]

That's more efficient than mine. I saw the detailed specs on it once, but the only number I've been able to find since is 99.2% efficiency @ 20 microns. In a separate thread, someone e-mailed Lubro Moly and they replied that the particles were too small to be trapped by an oil filter.

I reasoned they're probably about the same size as some of the largest additive particles in OTC oil; a filter would be too efficient if it filtered the additive package, so their response made sense to me and I set it aside. If I wind up with a filter caked with moly I'll let you guys know though

My oil consumption began to drop a few hundred km after adding mos2. Its still trending downward, but I haven't had to top up enough to put an accurate number on it. 25% is a conservative estimate in reduction to date. Even though its possible the timing could have been coincidental, and another additive could have accounted for the reduction, I'm more inclined to think the mos2 is playing some role in it.

My peak consumption was over a quart in 1,200 miles. I last added 10 ounces 350 miles ago and the dipstick is still at the full mark. That last addition was well after I'd expected to add oil. I'm keeping track of mileage, dates, and amounts added to get an accurate picture of how its trending. Not enough data yet to say anything other than that its down by at least 25% percent, and only began to drop after adding LM mos2 (though I'd like to think that at least some of the other additives I've used take partial credit too).

Spyder- Here is where I found the 98.7% @ 2 micron info I posted above. Looking at the website, that number seems to refer to all EaBP filters- do you know if they are all supposed to have the same filtering ability?

 

[Spyder7]

My understanding is that the filtering efficiency will vary somewhat from one size filter to another (i.e., different vehicles calling for different shapes and sizes will have an impact on how well the same filter construction, with the same media, performs across the different car manufacturer specified sizes).

That said, I believe its common practice for each company to quote the "best case" efficiency test for the particular size that tested the best, and, for consistency in advertising, to quote that number across their entire lineup of sizes (though if you read the fine print you should see exactly which filter size was used to achieve the advertised efficiency).

As this practice appears universal, I simply extrapolate from that when comparing efficiency numbers, not to get the true efficiency rating for my particular filter size, but to gain a reasonable comparative estimate at how the different brands do, overall, against one another.

Gary can probably shed more light on this, particularly on the Amsoil filter in question, as that product line is his particular area of expertise.

I will say that, as one who is using a high efficiency filter as well, I was initially a bit hesitant to try mos2 out of the same concern: that my filter would trap it before it could achieve the desired effect. After reading more about the specific particle size of their moly, and adding to that the reasoning I mentioned in a previous post, I concluded the additive would pass right through the filter and that it would not be able to trap it.

I believe Lubro Moly also addresses that concern on their website, and according to other members, they do respond to product questions and tend to be helpful.

0.5 microns is the size of a cold germ

I bought two cans of MoS2 the other day. I put 2/3rds of a can in my Subaru and my GF's Civic (it came out of the can a lot faster than I thought it would). I am very impressed with the it already. I have a harder and harder time feeling and hearing the engines when they are idling. If could be the psychological effect but for the price I can not complain.

My MR2 got the remainder of one of the cans and that will be the real test. It sometimes has days when the engine feels peppier than others and days when it feels just sluggish. It also causes the car to vibrate a little until it has warmed up the engine bay. Only time will tell if it makes a difference but I am optimistic.

My BMW has peppy/sluggish days. Seems to love cool moist days and hates very hot days. Every car i owned had this to some degree. I would say newer cars with better/better condition computer sensors/controls would behave a bit more consistent. BTW, mos2 seems to make my car run smoother and quieter. I like it!

This is a common theme among those of us who use it. I noticed nothing for the first couple hundred km, then the car began to seem smoother and quieter. I chalked it up to the time needed for it to run at operating temp for the plating effect to occur.

Its a good additive. While we could be collectively experiencing a placebo effect, I think it more likely that the mos2 is producing the effect its designed to do, and the subjective perception is constant with the theory as to how and why it works.

I've noticed from VOAs of PYB that the older formula (like most API SM oils) contained little to no moly (it wasn't required under the spec), while the new API SN PYB has a half decent moly count than what was in the older formula. They wouldn't be adding it back in at the level used if moly (which isn't cheap) didn't play an important role in aiding proper engine lubrication and wear prevention. Other additives (like its Ca package) have been beefed up as well, but it was the moly count that I was most struck by (and why I bought a jug of it as soon as it showed up here).

Ok, I drive a one ton van and use it hours on end hauling stuff, I currently use rotella t6. What is this lubromoly gonna do for my engine. Current mileage is 270 k. 328 v8 .

 

[tj90]

Ive been using MOS2 for the last year and I will continue to use it with M1. I see the rust color too during OCs for all my vehicles. I believe its nothing more than the additive suspended in the oil. When you hit it with a trouble light, you can see a sheen at certain angles. None of my filters looked clogged either so its passing through. The internals of my engines are clean so there is no way its sludge/rust as previous posters speculated.

I run 7k intervals on all my cars and usually add a quart to top off and rejuvenate additive packs at about 4 to 5k miles. I did it this time too but I dont know where my oil level was to start with. I wish I paid more attention so I could have determined if the MOS2 lowered oil consumption. The verdict is still out on my cars. I cant say the engines run smoother either.

However I have noticed 2 improvements. I added it to my B&S 4 stroke push mower and all smoking at start-up has stopped. Also, my porsche 911 used to occasionally smoke at start-up too and come to think of it, I have not seen that this past year either.

When I first was experimenting with MOS2, I added some to M1 in a glass jar. I noticed a big difference on how well the oil clinged to the side of the glass jar. Try it out. Simple experiment. I figure its got to help the motor oil stay higher up in the engine to protect at start-up.

In the US it costs $4 and change at Napa. Half a bottle treats 4 quarts of oil, and you can then half the dosage on subsequent Ocs and also only use it every other OC (the moly tends to remain awhile).

What it'll do: its an anti-friction treatment. It binds to the metals in the engine and fills in the tiny pores with a film that aids in lubrication. Moly is also anti-wear additive.

What you may notice is smoother and quieter engine operation after its given a few hundred miles to plate. What you won't notice is the anti-wear benefit going on under the hood that should help prolong the life of your engine.

Its not a miracle in a bottle (nothing in a bottle is, despite claims to the contrary by the additive industry), but I think its well worth the $4.

The company that puts it out are also well regarded, and the consensus of those of us who've looked into them are that they are not snake oil peddlers.

Its $4 at Napa. I use the same additives as you (and like yourself I also use a good engine oil), plus LM mos2, and I paid a good bit more than $4 for it (the Canadian markup) - and consider it worth every penny spent. Give it a shot.

Put a bottle in and let us know . Your driving should be the ultimate test.

I am pleased to know it is not just me! My mechanic thought i had a blown Head Gasket, but there werent any real symptoms of that.. i explained an additive was used, and we looked at the oil, and finding no water in the oil, we concluded it was the additive.

That oil almost gave me a heart attack. i felt as though i could do the "lexus glass test" with how smooth the Engine was with Mos2. Good stuff!

Maybe ill add it to PYB SN too...........................

 

[Spyder7]

Off topic:

I have PYB SN, but with a big stash of SM oils, I'm trying to use the oldest up first. I may also buy up some more SM oils if any of my usual oil haunts reduce prices to clearance level; otherwise I'm trying to resist adding more to my stash for awhile.
