Group III 4 cSt or VHVI-4 base oil is used for producing high-quality engine oils. Base Oil VHVI-4 is produced by hydroskimming unconverted oil at high pressure and is characterized by a high viscosity index, good cold flow properties, ultra-low sulfur content, low aromatic hydrocarbon content, and low vaporability.
Range of application
VHVI-4 base oil is used as a base for producing industrial, hydraulic, and engine oils, as well as drill fluids, and other agents. It neither freezes nor clouds up at low temperatures.
To transport VHVI-4 base oil, trucks, flexi-containers, and rail tank cars are used. For Base Oils VHVI-4 specifications, feel free to contact us – our sales department will help you choose a product for your specific application.
VHVI-4 advantages
- • A low pour point ensures high oil pumpability, quick starting at subfreezing temperature, which makes them usable in a variety of climatic conditions;
- • Thermal oxidation stability reduces the oil oxidation at high engine temperatures and scale deposition;
- • Low vaporability reduces oil refilling frequency;
- • Duration running of the oil in harsh operating conditions (the service life is 1.5-2 times longer compared to mineral oils);
- • Compatible with mineral oils and ethers.
