Old White Paper but still pertinent

Discusses the Chlorintated waxes found in Duralube and Prolong.

Also discusses the overbased Calcium Sulfonates.

The article sounds biased, noting the problems with zinc, phosphorous, and sulfur extreme pressure additives, compared to the benefits of Duralube and Prolong Oils but barely mentioning the fact that they contain chlorinated paraffins to get their good lubricity. The article completely neglects to mention that as the oil vapors are burned, which inevitably happens, the chlorine is released and forms HCl which corrodes the engine and the oxygen sensor.

I could not find anything on the overbased calcium

Is there some sort of a additive available thats along this line ? I cannot think of the name right now but it's very expensive and it's advertising contradicts it'self.

Molakule,we spoke about this product in a PM awhile back,do you remember the name ?

I remember Terry talking about oil extreme in UOA. I think he also said it is only effective for about 3K miles.

It was OilXtreme, an overbased calcium carbonate additive that had short longevity.
