OIL EXTREME™ TECHNOLOGY
JSL Technologies has developed a highly effective, non-chlorinated, non-sulfurized, non-leaded extreme pressure agent based on the calcium carbonate complex technology. Its chemistry is based on conventional, time-tested overbased calcium petroleum sulfonate.

Overbased calcium petroleum sulfonate is used traditionally by major additive manufacturers as alkaline reserves or alkaline boosters in engine oils. Its use as the alkaline reserve of choice in engine oil formulations by most oil majors is a testament of its safety as an ingredient in engine oil formulations.

JSL Technologies has re-engineered the conventional overbased calcium petroleum sulfonate such that it acquires an extreme pressure property besides maintaining its inherent alkalinity and anticorrosion properties. The re-engineering process does not in any way alter the basic configuration of the molecules such that the general formula of such molecules is still maintained. This is an important factor because the safeness of the compound as an ingredient in an engine oil formulation is derived from the expensive No-Harm Test done by the oil majors on their conventional overbased calcium petroleum sulfonate.

The extreme pressure property of calcium carbonate complexes in the OIL EXTREME™ technology is a function and balance of the following attributes.

  • Total Base Number (TBN) value
  • Molecular diameter of the carbonate in the micelles.
  • Crystalline structure of the carbonate molecules, and
  • Sulfonate to carbonate ratio
The interplay and balance of the four attributes are critical. The success of JSL Technologies is in its being able to determine the critical constants, ratios and numbers based on tribological theory of its own. It is this working theory that separates JSL Technologies from the others, making it possible to formulate an effective extreme pressure agent from overbased calcium petroleum sulfonate where others have failed.

The traditional overbased calcium petroleum sulfonate used by the oil majors in conventional engine oil formulations have TBN values of 300 or less. These compounds exhibit very little extreme pressure property. There are off-the-shelf overbased calcium petroleum sulfonates in the market today with TBN values of 400 or more, but they are either crystalline or have carbonate molecules in the micelles which do not have the critical numbers in the size distribution curve. Moreover, the sulfonate to carbonate ratio has to be just right in order to maintain stability of the micelles in the final oil formulation.

Failure to achieve any of these critical numbers above can result in the following quality concerns:

  1. Lack of extreme pressure property
  2. Precipitation of carbonates in long term storage
  3. Oil haziness, or
  4. Phase separation
