I got a number of emails on the issue of moly additives. Rather than resopnd individually, let me copy a typical response, since I cannot respond over and over:

Re"Lubro-Moly (A German oil with high moly content)
I cannot in good faith recommend this product. I am not saying it might not be everything it claims to be, only that who knows?

Nearly every quality oil today has some moly in it - the point is, oils are carefully crafted from a number of chemical compounds and added colloids, like moly - it is just one of many anti-wear materials. I do not recommend any additives, so let's pass on their additives, and concentrate on their engine oil products.

Now, what about their oil? Well, what about it? I searched on its name, and looked at every link, and could find no "science" about it - only ads for the company or its distributors, with all sorts of claims. There is nothing to back it up.

Personally, I doubt they have stumbled on to something that has evaded all the major companies - and the point is, an excessive amount of moly could be harmful to downstream components - who knows - do you? Neither do I! Is that a risk you are willing to take? And when engines routinely go 200k and beyond with only routine oil changes using routine mineral oils, what problem are we trying to solve here?

There have been miracle colloids before - PTFE, graphite, etc. I have seen disasters with all of them. The mfrs of moly and supporters claim that the "problem" of it either being filtered by the oil filter or becoming "glop" in the engine has been addressed - that suggests that there was a problem with glopping of earlier "miracle" products, doesn't it? Who knows if they have addressed it or not - where is the science? And why would any thinking person accept new "facts" from companies that have sold products that had "problems" before? Once burned, twice shy, remember?

Let's assume that it does everything it says - the soft "sacrificial" moly anti-wear compounds will be scrubbed into the metals peaks and valleys, which are called asperities - once filled, any more moly will not be pushed into these little divots, and is wasteful. Who knows how much is needed? Well, tribologists have a good idea - this is certainly an area where some is good, but more is not at all necessarily better.

Here is more info on moly, from a fan. But it leaves a number of questions unasnwered, many of which I have raised above.

I do not believe in miracles in a bottle - either for cars or for patent medicines. I tend not to put anything in my car or myself which has not demonstrated its scientific validity.

 

 

Hey, RoadRage.

So whats the status on the S? After the whole "test vehicle for Honda" mess, I can imagine the frustration and anticipation you have.

BTW, would you happen to know how Moly is kept in suspension? I know this was a big problem back in the day when Moly was first introduced into oils, since it would collect as a black mess at the bottom of the oil.

How did they resolve this?

At least someone is listening - mine are all flipped.

BTW, beware the small service station with a dusty 50 gal. drum of engine oil - a lot of the additives likely will have setlled - better to go to a Jiffy Lube where there is high turnover, or bring your own "flippers" to the gas station.

 

 

all my oil bottles are flipped too.

 

Interest is directly proportional to utility.
You certainly have my attention.
