We develop green engine oil additive based on the ionic liquid crystals. The new technology provides less fuel consumption and longer lubricant lifetime. The product has been designed for cold climate countries. One of the main features of our product that sets it apart from any other conventional solutions to the described earlier problem and puts it into its own niche, is presence of hybrid materials in the product’s composition, such as eutectic mixture of polyols and inorganic materials. As a result of this, energy storage capacity value of our product is equal to an impressive 320 J/g. Naturally, when added to the lubricant, it significantly boosts lubricant’s thermal properties as well. Apart from energy saving abilities, polyols demonstrate excellent lubricating properties as well as strong oxidation-corrosion resistance.
