What is the relationship between quality engine oil and cavitation?
For decades, automotive engine and transmission oils have been produced using traditional blending technology. The base oil and the additive package are loaded into a special blender (a very large mixer) and mixed at a certain temperature until a homogeneous substance is obtained. Commercial oil is then poured into barrels and jerry cans. But this technology can fail. As a result, additives may not be able to dissolve evenly in the base, negatively affecting the properties of the oil and thus the effectiveness of the protection of engine components. Therefore, the technology for the production of oils using cavitation seems promising.

The art of classical mixing in the production of automotive oils lies in the strict adherence to technology, which in theory should ensure complete mixing until a homogeneous mixture is obtained, additives are evenly distributed over the volume of the base. But in practice, not everything happens like this and unfortunately not all batches of oils match the reference sample in terms of chemical composition and performance.

Hence the stories about sediment in motor oil.

Is it possible to change the technology of mixing the base oil and the additive package. Such a technical solution has been found and has already proven its feasibility in practice. The technologists of the French company SARL RIXX Corporation, which produces oils under the RIXX brand, use so-called cavitation columns instead of classic blenders. The idea is simple and ingenious – to aid the phenomenon of cavitation, which is known to car owners as a force that destroys pump impellers and cylinder liners.

Recall that cavitation manifests itself in the form of micro-explosions (collapse) of air bubbles, which thereby pull the smallest particles out of the surface. In mixing installations, under the influence of micro-explosions of bubbles, the mixing of the base and the additive package actually takes place at the molecular level. Hence the name of the new technology – molecular mixing.

According to the results of laboratory studies, the homogenization (uniformity) of commercial oil with this mixing method is 100%. The raw material of an oil made from the same base and additive package using the technology of molecular blending and classical blending may differ by 15-25%. And this is already a serious bid for a technological breakthrough.

SARL RIXX Corporation’s molecular blend oils have proven their high performance by receiving the highest approvals from the American Petroleum Institute (API). In particular, the company’s line includes products of the highest quality class to date, API SP and ILSAC GF-6, designed for the most modern engines. They are made with formulations and additive packages from Afton Chemical and Infineum, and the base is a blend of Group III and IV oils (hydrocracking + polyalpha-olefins) in a ratio of 70/30 or 60/40, depending on the formulation.

The RIXX oil line includes low ash products designed for state of the art Korean and Japanese engines, and ACEA C2/C3 medium ash products to be poured into the engines of most European cars.

A unique development is 10W−40 API SN/CF oil based on Group III, IV, V base oils, designed for heavy duty engines with high power output or for machines operating in hot areas with high temperatures. This oil is popular with rally teams, but also with owners of cars with upgraded engines.

The uniqueness of the 10W-40 API SN/CF oil formula is that, despite its quite high viscosity, it does not increase internal losses in the engine and does not reduce power, effectively protecting the engine when used in extreme temperature conditions.

RIXX oils have been present in Russia for a long time and there is an official representative. Therefore, the opportunity to try the latest technology for your car is already there.
