Anyone have any experience with the Lubromoly Mos2 for Manual Trans and Gears? I was looking at it and thought it couldn't hurt. I've been using the Mos2 Engine treatment in several applications and like it. I was just wondering if there is any reason not to use the Manual trans formula in a FWD manual transaxle. I know that many manuals require a GF3 or 4 to protect "yellow metals" and just want to make sure there are no negative's to using this.

I have tried it twice....useless snake oil waste of money. Use Redline MTL or MT90 if you want a decent trans oil
You would think if that's what it's for it would be fine. But I suggest you shoot them an e-mail and ask them your specific question directly. I've found them very attentive and responsive before when I had questions about MoS2.

Ok so did you expect them to tell you their product was no good?

I could say the same thing about MTL vs other MT oils...
I cant see how MoS2 solids could be smart in a synchronized transmission that relies upon specific fricton characteristics between surfaces.

If I really thought it worked I'd be worried that it would reduce the friction of the syncros to the point you'd be grinding between every gear.
But since I think it doesn't do anything beyond what any other MTL would do I say go ahead. Your money.

I've used it for over 150,000 miles in my diesel jetta 5 speed along with pennzoil synchromesh. I tried a number of fluids before this including redline and all produced inferior results. I've been draining and refilling every 30,000 or so and this combination has performed flawlessly. I highly recommend the mos2 for gears (and the penn. synchromesh). 240,000 miles on engine/transmission with no transmission issues (before I began the synchromesh/mos2 The shifting was awful and second gear would fight me constantly - even with new shift linkage and proper alignment).

I'm not familiar with the product- is it a fully formulated gear oil along the lines of RP Sychromax, Redline MTL/MT90 and so forth? If so, it should be fine.
If its an ADDITIVE meant to be mixed with a GF-4 gear oil, then I'd be concerned that it won't allow the synchros to grab well enough and you'll get gear crash when shifting. And besides, its getting hard to find GF-4, and GF-3 is just about impossible.

Uh, no.
I actually had a detailed question about mixing it with something else. They were very good about looking into it before responding and not giving me some canned non-specific company line answer.

I've used the Lubro Moly MOS2 in engines.
Not sure if I would want any of that stuff in my Transmission.
Moly does not agree with friction plates.

If you are lucky or have aggressive synchros, you may get away with it.
But I can never recommend it.Yes, it would be good for other parts, but not worth the chance for shifting.
BTW, it is tough to remove the strongly bonded moly.

I've posted a testimonial of over 150,000 miles of its use with no ill effects. Shifting is as good or better on a trans with known synchro issues in second gear compounded by high milage. Ran the gm synchromesh for a few thousand which improved shifting significantly then added the mos2. Over the last 150,000 miles the shifting has only gotten better. I would recommend both mos2 and penn (gm) synchromesh to anyone with a normal manual trans. During previous transmission fluid changes, (including redline and other high end brands) I always had visible metal when a flashlight was shown on the drained fluid. With synchromesh and mos2 this has all but been eliminated. Speculation is one thing, but I feel strongly that this stuff will not harm, but help based on actual use (no used oil analysis though).

Absolutely, many times. And on key at around 10-15k miles, and a visit to cold weather, it would get really hard to shift.
Switching to Amsoil has given me consistency for many tens of thousands of miles.

In my experience with liqui-moly everything they produce works as advertised. I have yet to have a single issue with any of their additives and use the mos2 in every engine I own.
Every product I have used bearing their name has performed exactly as they said it would.
I have never used this product in particular however I expect it will work exactly as all the other products they make which is exactly as advertised.
Liqui-moly is the only company I will buy additives from. They answer emails intelligently and not just the proprietary info/can't really say blah blah blah.
I don't believe for a moment that they would make a product for your transmission that would hinder it in any way so I say give er a shot.

Once again, you are taking a big chance by using moly with synchros. Don't do it.
like I said, luck or aggressive synchros can't be counted on.

This is for Manual trans and differential.

Yeah. I doesn't specifically mention anything about synchronized transmissions. It says all transmissions and axles without self locking diffs. I'm not sure if I totally sold on it in a manual...
