Rotella and MoS2, a perfect combination???

Which leads to tinkering. I love to blend and a good additive to experiment with is mighty hard to resist.

My thought with the Rotella was it's ZDDP is only 25% or so above basic SN PCMO's, but it lacks any of the extra anti-wear additives PCMO's use in conjuction with ZDDP, so I was thinking maybe MoS2 might really thrive in it.

QS Defy has ZDDP levels closer to Rotella but it still uses 200 ppm Boron and 100 ppm Moly in it's add pack. Hmmm....

Well I know how this is going to go... I'm gonna have to try it! LOL.



Zddp is anti-wear. Moly is a friction modifier. They are different. Just clarifying.


ZDDP is EP ( extreme pressure) moly is AW and friction modifier.
Id you get a chance read up on some of molakules old posts in question of the day and interesting articles. I found it very interesting.


To the op.
Give it a shot! It wont hurt anything. But if it were me, I would think about T6. It has moly already.
 
It's fairly rare to see an engine oil without either an API or ACEA approval, but for oil additives there are not even any defined standards.
As far as I understand the present legal situation, you could bottle salt water and sell it as an oil additive without fear of any legal consequences, other than possible product description issues.

Only way to know is to try it!

I wonder if it will be quieter than PYB.

Would MoS2 affect this? I haven't read anything about MoS2 causing skirt damage. If there is any evidence of this, please point me to it. I'm not arguing, I'm genuinely interested to know, as MoS2 is one of those things I have not researched in depth.


Only some of the original cheap versions of Moly caused direct side effects when too much was used. If you use too much AW or EP additives they can cause deposits in the exhaust system over the long term, but won't cause any real main block damage.
 
Thanks for all of the responses, I appreciate good discussion most of you can read just fine thank you, the one of you who can't is on ignore anyway I suggest the rest of you do the same.

As was so aptly pointed out earlier, this IS the oil additive section, for discussion of oil additives.

My apologies BITOG'ers, for clarity the Rotella I favor for the Jeep is the dino T3 10w30 variety. I've run it quite a bit in the past and liked it, never UOA'd it yet though.

Didn't realize T6 had moly, interesting.

Thanks! Exactly what initially led me to start fiddling with MoS2 in the first place. I just read an old post from Molakule where he mentioned Boron as being very kind to pistons. Maybe I'm on the wrong track with moly.

No, I have not heard anything about MoS2 & piston skirt damage. Its the Jeep 4.0 engine that has a problem with piston skirts. So the most likely thing will be the piston skirt fails before the engine wears out. So the MoS2 will not help or hurt as far as when the engine fails.

Thanks! Learn something here every day, I had missed that. Now I'm wondering which would take care of those piston skirts better.

How does moly compare to boron? Also a friction modifier?

You're doing this not to "save money" or "extend the longevity of the motor", but to give yourself something to do. You already know what to expect, and hey, if you do happen to stumble across something great, all the better, right?

If I'm wrong about any of the above, then perhaps you should reconsider how you're spending your money (I say "perhaps" because far be it for me to tell one how to spend their own money, like some here would try to do). However, if I am correct and you are doing this as a form of (safe and relatively inexpensive) entertainment, ignore the naysayers, add the MoS2, and enjoy yourself.

We (well, some of us, at least) appreciate hearing about this type of experimentation just as much as we appreciate conducting our own experiments.


Scary... like looking in a mirror, you nailed it brother!

A few dollars to experiment with an oil filter or bottle of additive is peanuts for dollars as far as hobbies go IMO. High value entertainment return for very little $$$.

Hmm... I must have been lucky with my 4.0. I did so much stupid [censored] to that engine but when I tore it down it was clean inside, the cylinders still had visible hatching, and this skirts were clean and had very few scratches. This was in a 91 Comanche, torn down for the [censored] of it in 04.

I'll admit I never really researched that motor much, as I never had any issues with it. Moly (in the form of a tablespoon of black moly grease with every OCI) may have contributed, but I only owned it for 3 years before I tore it down (and another 4 after, then I sold it running better than when I bought it) and I know the previous owner abused it pretty horribly. I wasn't sure if there was something inherent in MoS2 vs other forms of moly that would alter the performance.

I'll tell ya what, man! I'm a techie, personally. My hobbies are f**king with my car and tearing into electronics to determine build quality. Since my wife likes to eat, she has a strong preference for one or both vehicles to be in a state of disrepair at any given moment. The kinds of devices I buy and tear apart aren't exactly cheap

I know it wasn't directed at me, but thank you! I don't have time to read it now, but I bookemarked it for future reference. I think I read this back when it was originally posted, but it's been over a decade, so I'm sure I'll get something out of reading it again.
 
Maybe 4.0's have piston skirt problems. If they do, they do. But I personally know a ton of these engines that have been SEVERELY abused for a long, long time, and they are still running. Some of them sound like a jar of marbles at a stop light, but they keep running. I've yet to see or hear of a 4.0 dying short of 250k miles.....unless it was run DRY of oil.

But regardless, Donald and Astro, you can say what you want, and I'm going to continue to ignore SkyHi, and I think you guys have a lot of good things to say on this forum....BUT when the OP specifically says "oil additive hater, please shut yo' mouths" and then ya'll come in here running with a 2x4 in your hands ready to bash someone.....how can you explain that.

Use some logic: this is an oil additive forum. People on this forum are going to use oil additives and report their experiences OR people are coming on here to learn about other people's experiences. That's pretty much it. Even noobs don't want to hear some of this stuff....it's so distracting.

Experienced BITOG'ers and Noobs want to hear people's oil additive experiences....whether they be good, neutral, or negative. We are big boys and we want to make up our minds.

Thank you for playing.

Kcjeep. I wasn't trying to be a (phallus?) I just wanted to clarify for any possible readers.
And I couldn't agree more with the above post. It's an oil additives sub forum,therefore the discussions will be about additives. Why do jerks jump in and chirp when obviously they add nothing to the discussion. Most of us are here to expand our knowledge so how does a dont use additives comment expand anything other than the posters obvious ego and super inflated holier than thou,I know better than you,idiocy. Like really. If you don't like,or have no experience with,then why bother even posting.
We have a guy or 2 who are on an anti additive mission. Which everyone is aware of,so why degrade a thread with the anti additive drivel. Like really.
Anyways I'm glad tree are guys like ken and phishin trying new things.
Or you can be a follower and never think outside the box,never try anything new,and have nothing better to do than copy and paste and pollute informative threads with uninformative comments.

No not at all I appreciate the input, that is discussion and learning, hopefully why we are all here.

Still wondering if moly is classed different than boron. I read the link electrolover posted and it sounded like moly was classed with ZDDP? Sorry much of it was over my head.
