You want moly?

It looks likes Schaeffer's oil has plenty of moly in it, plus an excellent additive package. Look in the passenger car motor oil section. I remember when Schaeffer's oil was discussed here a lot. And this moly comes with the oil-you don't have to add anything.

I had some good experiences with Schaeffer's oil.
 
The nice thing is you don't have to add anything and play chemist-the moly is already there. Compared to those other motor oils the Schaeffer's had a lot of moly. But you have to order Schaeffer's oil and it is expensive. Still, when you add up the cost of a motor oil plus the additive maybe the Schaeffer's is not really more expensive.

According to Molacule, antimony and soluble moly of any type clash, counteract, and compete with each other to the point where it has to be one or the other, but NOT both in an add pack.

PLEASE correct me if I have this wrong, Molacule (or any other tribologists on here)!!
 
Am I supposed to be adding something to the oil I use? When did this start?

LMAO!! I am with you. I guess I havent found a good antimony source yet so start adding it to my PYB

I am not saying that anybody has to add anything to their oil. But a lot of people do, and there has been a lot of discussion here about adding various moly supplements to motor oil. An example is the Lupro-Moly supplement. I brought this up after I checked out the comparisons of motor oils that was shown in the Passenger Car Motor Oil Section. No conspiracy here or anything like that. I just pointed out that the Schaeffer's oil already has a lot of moly. At least compared to the other oils.

I also have a limited amount of actual experience using various Schaeffer's products. Their motor oils are used in racing to some extent and at least in the past they sold an oil supplement and a product called Neutra for the gas and the oil.

So I don't think it is out of line to bring up in the Oil Additives Section that Schaeffer's oil has a lot of moly. Especially since there has been a lot of interest here in moly supplements.

It is interesting to me that a simple little discussion about moly in Schaeffer's oil brings out comments from a few people who seem to rarely comment on anything. Did these same people comment on Lupro-Moly?

I have been here over ten years and there used to be a lot of discussion about Schaeffer's products. And for the record I have used some Schaeffer's products and they seemed to work well. I suppose the chemists at Schaeffer's studied to see how their additive package worked and if the moly and other additives worked together okay.

But maybe it is not allowed in the Oil Additives Section to point out when a motor oil has more moly than other motor oils.
 
I don't know. According to some of the oil companies other additives have been developed that are cheaper and just as effective or more effective than moly. One example is Titanium. Other people say that they are just trying to reduce cost. Maybe Schaeffer's Oil is behind the times. Maybe moly needs to be removed from motor oil.

But I think it is interesting that Schaeffer's does have a considerable amount of moly. I didn't think it would be out of line to bring up a discussion about this in the Oil Additives Section.

I believe this is what I said:

Quote:
As with MoTDC’s, these organic antimony compounds also act synergistically with ZDDP compounds in motor oil. It is believed that sharing of the sulfur and phosphorus atoms contribute to the creation of surface films composed of layers of ferrous sulfate and ferrous phosphate, with the organometallic components depositing a plastic layer of antimony and zinc sulfates and phosphates.


The results were from a scientific study.

RLI uses about 375 ppm of antimony in their current formulations.

Not being a wiseguy but... If moly is so great for the engine, why is it mostly removed from many major brands?


In many street brands the moly used is the tri-nuclear moly chemistry and one doesn't need as high a level wrt to the other additives used.

RLI has a booster additve for racing applications:

The horrors!

You can have my moly when you pry it from my cold, dead crankcase.

I see this "tri-nuclear" moly bandied around a lot here, particularly every time a favorite oil is seen to be lower in moly than others.

Is the tri-nuclear moly actually cheaper than what we are used to seeing, like the type in say PYB? I assumed it was more expensive and therefore not likely to be in some of the low to mid tier oil offerings that often show low levels of moly in UOA's.
 
I liked the idea of moly in the oil. I figured it was better if the chemists who developed the motor oil included the moly in the additive package rather than somebody adding moly later as an additive.

Of course if something better is developed that is fine. But for right now if somebody wants moly in oil Schaeffer's might be a good choice. Otherwise maybe Redline.
