VHVI TECH is SK's proprietary oil technology that creates the benefits from SK's highest quality VHVI
base oil, YUBASE, and the additives of careful selection.※
VHVI : Very High Viscosity Index




Contains no harmful impurities in YUBASE interrupting additives performance, so provides better
engine cleasnliness and engine protection by cutting-edge additives.



VHVI TECH has much less light oil portion that vaporizes in hign temperature engine and leads to minimizing oil consumption and saving your money.


Lube Base Oil mostly has Hydrocarbon compounds of 20-45 carbon number and can be classified into 4 primary types: Paraffins, Napthenes or Cycloparaffins, Aromatics and Heteroatom compounds. Heteroatom Compounds contain in addition to compound sulfur, oxygen and nitrogen. These compounds are removed because they tend to result in base oil instability or low viscosity index.

The Vacuum Distillation Unit separates the oil into the desired viscosity grades of Hydrocarbon compounds group between 20 and 38 carbon number which we call lube distillates.

Iso-Dewaxing uses a catalyst to convert waxy materials into isoparaffins. This results in higher yield, lower pour point and higher VI.

Hydrofinishing involves treating the base oils with hydrogen which removes 1~3 ring Aromatic compounds.

The choice of oil is very important for your engine. The most obvious function of the engine oil for lubrication, but the engine oil protects against corrosion and components of the engine and cleans the deposits and contaminants which may arise as by-products of combustion. Engine oil is also responsible for cooling. Therefore, we recommend that you make your choice without compromising on quality.
