Group I

Solvent-refined

Classic solvent-refined base oils with natural solvency and excellent additive response — dependable grades for general-purpose blending.

UNIQUE drop-white SN 150 GROUP I BASE OIL
Group I

SN 150

A light-viscosity solvent-refined base oil with excellent solvency and additive compatibility. The workhorse grade for general-purpose lubricant blending.

UNIQUE drop-white SN 350 GROUP I BASE OIL
Group I

SN 350

A mid-viscosity solvent-refined grade bridging SN 150 and SN 500 — a flexible blending stock that widens viscosity coverage without reformulation.

8.2 – 9.0 cSt @100 °C ≥ 95 VI

UNIQUE drop-white SN 500 GROUP I BASE OIL
Group I

SN 500

A heavy solvent-neutral grade offering strong film strength and natural solvency, ideal where higher viscosity and additive uptake are required.

10.5 – 11.2 cSt @100 °C ≥ 95 VI

UNIQUE drop-white Bright Stock 150 GROUP I BASE OIL
Group I

Bright Stock 150

A high-viscosity residual base oil delivering exceptional film thickness, tackiness and thermal stability — the classic thickener for heavy formulations.

29.5 – 32.0 cSt @100 °C ≥ 92 VI

Group II

Hydroprocessed

Hydrotreated base oils with very low sulfur and saturates above 90% — superior oxidation stability for modern formulations.

UNIQUE drop-white N 150 GROUP II BASE OIL
Group II

N 150

A hydroprocessed light grade with very low sulfur and aromatics, high oxidation stability and consistent quality shipment after shipment.

5.0 – 5.3 cSt @100 °C ≥ 100 VI

Group III

Severely hydrocracked

Very high viscosity index base oils delivering synthetic-level performance for low-viscosity, fuel-economy formulations.

UNIQUE drop-white 4 cSt GROUP III BASE OIL
Group III

4 cSt

A very high VI, low-volatility grade produced by severe hydrocracking — the foundation for fuel-economy and low-viscosity synthetic formulations.

4.0 – 4.4 cSt @100 °C ≥ 120 VI

UNIQUE drop-white 6 cSt GROUP III BASE OIL
Group III

6 cSt

The most versatile Group III cut, balancing volatility, viscosity and VI for mainstream synthetic and semi-synthetic engine oil production.

5.8 – 6.4 cSt @100 °C ≥ 125 VI
View full specification
UNIQUE drop-white 8 cSt GROUP III BASE OIL
Group III

8 cSt

A heavier Group III grade providing high-temperature film strength with synthetic-level stability, for demanding high-viscosity synthetic blends.

7.6 – 8.2 cSt @100 °C ≥ 125 VI

Quality & sourcing

Consistency is the specification that matters most.

A base oil is only as good as its repeatability. We qualify every refinery source, test against agreed specifications, and document every batch — so the drum you receive next quarter performs exactly like the one you received today.

Qualified refinery sources

Long-term offtake relationships with established Group I, II and III producers — no spot-market surprises in your supply chain.

Certificate of analysis, every time

Each shipment travels with a COA covering viscosity, VI, flash point, pour point and appearance, tested against the agreed specification.

Pre-shipment & independent inspection

Third-party inspection (SGS or equivalent) available at loading on request — quantity and quality verified before the cargo moves.

Technical support for blenders

Our team helps you match grades to formulations, interchange between sources, and plan viscosity coverage across your product slate.

Packaging & logistics

From a single flexitank
to a full vessel.

We deliver by road, rail and sea across Türkiye, the Middle East and Central Asia — in the packaging that fits your operation.
