Rotella and MoS2, a perfect combination???

Thats because moly is mainly an AW and boron is just an FS and boron esters are pretty good at cleaning too.
Just like read all of molakules posts.

do that and you will have a better handle on things than most people here.
 
I'd use that combo. Mos2 is a good friction modifier and Rotella a stout oil. Every vehicle that I've used Mos2 in has resulted in positive side effects. Typically, a quieter running engine and a slight increase in fuel economy.

As for insolubles, I'm not worried about it as the average particle size is only 0.3um.

Also, there's a member here; wag123, who has been using Mos2 since the early 90's. None of his engines have suffered any ill effects.
 
What 'results' are you expecting? How does one quantify the 'results' from these friction modifier adds?
The engine didn't blow = success? UOA #s?
I fail to see the usefulness of UOA in consumer applications, so if you're experiencing a significantly quieter drivetrain or *measureable* increase in MPG or power, that's what I'd consider real benefits.

I remember reading some people who touted more MPG with MoS2 - piqued my interest a bit. Also lots of nay-sayers too.

You should never judge the performance of an oil or additive just from engine sound. Engine sounds can be very deceptive and a lot of engines that go bang from lubrication problems sound just fine before the final seconds. Adding a thickner for example will reduce rattles when hot, but can then cause a failure from lack of oil flow when cold.
If you do experiment with additives, stick to those made by a real engine oil company and start doing used oil analysis to see what is happening, that way you will learn they tend to be a waste of money sooner.
 
I have to chuckle whenever someone brings up the 4.0 being "prone" to piston skirt failures.

I just don't see it, and I've been on Jeep forums for years now. I guess it is one thing that does happen to the 4.0 to finally kill it at high mileage (>200k usually) or when it's over-revved (it does NOT like high RPM, and wasn't built to make any power at high revs anyway so no one with sense should ever hold it over 4000 RPM for more than a few seconds anyway- but kids playing in mud WILL do that to 4.0s not knowing any better). So maybe since 4.0s rarely die before the vehicle they're in or before the owner gets really really tired of them, maybe it does stand out somewhat as a cause...

Piston failure is not exactly rampant, and no 4.0 owner should drive around "worrying" about it or tweaking his oil mix to try to somehow compensate. If you've got a 2000 or early 2001 (like mine) you really should think a lot more about head cracking with the early "0331" head casting, and make double-dang certain you never EVER overheat the thing. Put your maintenance dollars into over-killing COOLING system maintenance! If you have a 99 down or 01 up, there's really nothing to "worry" about with a 4.0 at all.

I've been using the MoS2 for about 10k now and I have no plans to stop. My engine is quieter, and mpg is at an all time high for this vehicle (over 19 mpg average, very good for a heavy inefficient Jeep).

I do want a used oil analysis to see exactly what moly level the MoS2 is creating at my current application rate, as well as to get an idea if anything is going on inside I need to know about as I've not had a used oil analysis done ever for this vehicle.

Besides, it's fun. Cheap hobby. MoS2 is relatively cheap as well. I can handle 6 bucks for 5k or more.

BUT... after the links were posted it looks to me that MoS2 is going to do much what ZDDP does. I was thinking they were different. With Rotella's higher ZDDP levels maybe I need to look into something boron heavy to go with it.
 
Liqui Moly Ceretec works better than simple Moly when used with an oil that has a good add pack already and I've not seen any adverse reactions in any used oil analysis. LM say it's supposed to last upto 50K km, BUT that is not true as it only seems to be effective in the first OCI. Ceretec contains Moly, Boron and Ceramic particles.
If you must spend money on additives for a good oil, Ceretec is the only one I have seen that might just work, but you should do a before and after UOA to see if it does produce a result.
 
-Exactly....I'd like to know why I have a hard time coming to the "Oil Additive" section because it's constantly being policed by the Anti-Additive Gestapo!!??!! I'm an oil additive fan, and I like to brew my own batches per OCI, yet most of the Police on this sub-forum ruin it for me.-

Seriously - I too enjoy tinkering with various combos and products.

They should change the name of this site to Bob is the opinionated oil guy.com

anyway- keep on truckin.

I use MOS2 as well, great product, use it in everything with an engine with great results.
 
Skunkships posts carry no weight. I've got him on ignore because he adds nothing to a conversation.
MOS2,the liqui-moly brand is great stuff and is high in boron too. I broke down and put a can in last night because I lost 3mpg in the last 2 oci without it. Should see results by the end of my second tank of fuel.
I've always had positive results with it,in every engine I put it in. Others may have different experiences,mine however are positive with mos2.

How many used oil analysis have you seen with Ceratec? I haven't personally seen any "bad" used oil analysis with Mos2 either.

There are some on this site, including one for an adverse insolubles reaction, but luckily I have access to the German VW TDI data files from the chaps in the ZF oil analysis lab. If you ask some chap in the TDI forum they have got copies of some of them, although they all relate to VW diesels. Luckily because I get to meet with the chaps from my local oil lab every few weeks if I have a question about additives I can ask them.
Some of the new generation of engine oils have started using Masnesium based detergents rather than Calcium and for some reason those new oils don't like extra additives, although I don't know if it is the Moly or the base stock it is in that causes the reaction.

Painful just painful to read this bloody tripe every single day.

That's why so many of us have him on ignore, he was even specifically uninvited off this thread at the outset yet he still doesn't get it. And NO I have not read any of his posts, but skipping over 2-3 posts in a row to get to intelligent posts is annoying. Stop replying to him guys and put him on ignore, life is too short to get sucked into such garbage.

I have a hunch that the majority of his posts are chock full of scathing sarcasm (of the Monty Python variety) that would be quite amusing if it were heard in the tone it would normally be spoken in. I asked him to verify this, but received no response. I almost wonder if he has me in ignore

I am something of a Monty Python and John Cleese fan!
I don't have anyone on on block apart from a few who have difficulty in using the Queens English correctly, as some of those selling Moo oil or other snake oils often do.

After I use some Pennzoil Platinum to make sure my engine is nice and clean I am thinking about trying the Liqui-Moly brand Moly oil supplement. I have not tried it yet but two other oil supplements I have had very good luck with are Schaeffer's oil supplement and Lubegard BioTech Engine Supplement. These are some of the very few oil supplements that I believe in.

One of these days I am going to order some of the Lubegard nonsolvent engine flush. I will probably use that this summer. I have had very good luck with Lubegard products. I like the idea of a nonsolvent engine cleaner.
