Properties, features of Synth Optimal Liqui Moly

Lubricating fluid Synth Optimal LIQUI Moli is a pure synthetic material made on the basis of special base oils using hydrocracking production technology, with the addition of a set of additives.

Due to the additives, low consumption for fumes and evaporation is provided, fuel consumption is reduced, and high-quality lubrication of rubbing parts of the ice occurs. In addition, we can note such qualities as:

    • Resistance to heat,


  • to maintain the level of viscosity at a predetermined level,
  • No foaming at temperatures up to 200 degrees,
  • Due to the use of zinc and phosphorus, as part of additives, an oil film with a high degree of strength and an increased sliding effect is created.

It has the following positive properties:

  1. Decent durability,
  2. Good stability in operation,
  3. Soft engine running,
  4. Slow aging,
  5. Providing the desired properties at low temperatures,
  6. lubrication system Pressure at the required level under all conditions,
  7. Preservation of working parts from wear,
  8. Ability to keep the motor clean,
  9. Reduction of harmful emissions into the atmosphere,
  10. fuel Economy,
  11. ice resource Increase,
  12. Can be mixed with other types of oils,

Plus, the engine oil was tested when working with turbines and catalysts.

Additional information

In 2016, the engine oil brand Synth has undergone some changes, namely modifications undergone its composition. After improvements, the lubricating fluid still retains its versatility and can be used for gasoline and diesel engines, but now these types have been added and biofuels.

You can identify the new product and slightly changed the name, which is now red and added the letters «HT» ie it is now fully called Optimal HT Synth.
