Planning to add a can to my oil on my Subaru ForesterXT. I will do a UOA
Has anyone seen an analysis of the product or a UOA or an oil with this added?
 
I bought a couple of bottles of the 16.9 ounce 'Truck Series' LM MOS2 when they were on 'Clearance' at AZ a couple of years ago for $7 IIRC. I added about 4 or 5 ounces to the oil on the first few OCs on our Mazda CX-30 to try to replicate the Mazda OE (high moly oil) and also because the 5 quart jug only brings the level half way between 'add' and 'full' even though it's supposed to be a 4.8 qt. capacity.

IDK if it did any good but I doubt it did any harm in such a small amount. I certainly wouldn't add the entire 16.9 ounces.

If you were running an old clattering diesel on obsolete engine oil 40-50+ years ago it may have helped to quieten it a little but it has no place in a modern engine, if you want your engine to live the longest possible life use a high quality engine oil and keep aftermarket additives out of it, the oil has everything it needs.

Today it falls into the snake oil category. From LM own website..
Specifically designed for older engine designs with or without a turbocharger.
 
Does OPE like mowers and generators qualify as older design to use it up in?
Probably won't hurt them. But as good as modern oils are, i don't see the benefit. In fact, most generators sit a lot! Unless its on a food truck , it sits a lot, leaving so much opportunity for the mso2 particles to drop out of suspension.
 
If you want to use a moly additive, Lubegard Biotech is a better choice.
Possibly, it's pretty thin for a 20w even though your only adding about three ounces per QT. I would look at a high moly oil on the higher hths value like maybe Redline 5w20 at three ounces per QT or a product of the like. Maybe even the @High Performance Lubricants Engine Cleaner 30 as it looks like a stout 30 though I think you can't use it over long continuous full strength applications. Search recently for voa of high moly and boron in your weight of choosing

Agree, even in ope or generator your only going to be using 30mL per qt so the can would be around for 10 years so Im sure it would degrade before it's all used up.

Yes. Many times...you can find them searching in the UOA sub with my user name. Just a big spike in moly as you would expect. Don't let the BITOG doom and gloomers talk you out of it 🤣

In before.....

I think it helps with cam and valvtrain wear in most engines. Mos2 specifically, more than other forms has been shown to reduce wear in those areas. I've run it in multiple vehicles with well over 500,000 miles (that I still own).

I've done (visual) inspections on engines / camshaft where it's been run from new or almost new and they have no discernable wear on vehicles from 300,000 to 750,000 miles. Roller and flat tappet. Good maintenance and oil helps here, but the mos2 definitely hasn't hurt.

I've opened oil pans and inspected engines (non- failure related) and have never seen evidence it has settled out - even in engines used infrequently.

If it's not an engine you plan to keep for a long time or it's lightly loaded, it's likely a waste of money.

Always figured it would be good for timing chains.
