overbased CA sulfonate old school been around for years is used in motor oils and HDEO aswell as metal cutting oils IMHO other than a boost in TBN offers NOT much in wear reduction it works MUCH better if you have some free sulfur in the oil mix.

so, the properties that allow asperities to be filled is false?

That is what is claimed

covers it all it may work in PCMO,s but I think you need >5% or so which would hurt in the ash department that is why majors do not use a lot of it.

I have no idea what Brews just said but is sounds pretty good to me. We need more like him on BITOG.

Thanks for the link Bruce. They show their crystalline products w/ sulfurized olefin to out do CP by a factor of 3 on the 4 ball. Somehow I have a problem believing that.

The corrosion tests are also interesting in that not all of their products passed. It appears that the type of Calcium Sulfonate is important to what you are doing.

tapping stainless steel with a cutting oil with chlor Versus NO chlor BUT the CA and sulfur had problems in 1 test I did so I was NOT very high on this stuff tho I do use it but for TBN boost only.

Thanks Bruce. Crystalline anything seems like a bad idea in a lubricant. Could the precipitates become abrasive in use? Particularly in large %?

thanks Bruce,
guess there is no getting around what takes years and numerous R&D dollars to prove. side step one land mine only to find another in my path. wont be using the oil extreme.
