Group I solvent-refined base oils produced at the Türkmenbašy Complex of Oil Refineries to TŠ 05766698-60-2016, in five solvent neutral grades from SN-80 to SN-1200. All grades are supplied against a certificate of quality and are available in bulk or drummed. SN-180, SN-350 and SN-600 are the grades regularly offered for export; SN-80 and SN-1200 are produced to order.

Grades
Base Oil SN-80
Kinematic viscosity at 100 °C 2.5–3.5 mm²/s, flash point (open cup) min 170 °C, pour point max −12 °C, density at 20 °C max 870 kg/m³. Group I solvent-refined base oil — the lightest grade of the range, used in spindle and light hydraulic oils, process and extender oils and as feedstock for further refining.
Base Oil SN-180
Kinematic viscosity at 100 °C 4.5–6.0 mm²/s, flash point (open cup) min 205 °C, pour point max −12 °C, density at 20 °C max 880 kg/m³. Group I solvent-refined base oil — a light neutral widely used for engine oil, hydraulic and industrial blending, and the grade most regularly shipped to India and regional blenders.
Base Oil SN-350
Kinematic viscosity at 100 °C 8.0–9.5 mm²/s, flash point (open cup) min 220 °C, pour point max −12 °C, density at 20 °C max 890 kg/m³. Group I solvent-refined base oil — the mid grade of the range and the general-purpose blending stock for engine, hydraulic and industrial oils.
Base Oil SN-600
Kinematic viscosity at 100 °C 11.5–13.5 mm²/s, flash point (open cup) min 225 °C, pour point max −9 °C, density at 20 °C max 900 kg/m³. Group I solvent-refined base oil — a heavy neutral for heavy-duty engine oils, gear oils, greases and industrial lubricants.
Base Oil SN-1200
Kinematic viscosity at 100 °C 18.0–23.0 mm²/s, flash point (open cup) min 250 °C, pour point max −9 °C, density at 20 °C max 905 kg/m³. Group I solvent-refined base oil — the heaviest grade of the range, used where a high-viscosity component is needed in gear oils, greases and industrial formulations.
