About Sinolook Base Oil

A complete base oil portfolio, backed by world-class refineries

Base oil is the foundation of every finished lubricant — typically 70–99% of the formulation. The right base stock determines viscosity, oxidation stability, fuel economy, and OEM approvals.

Sinolook supplies all five API base oil groups plus specialty white oil, sourcing from ADNOC, Formosa, and trusted refineries across the Middle East and Asia-Pacific. Every shipment is SGS-inspected at four checkpoints — from shore tank to your storage.

Quality Control

Four-checkpoint SGS inspection on every shipment

Sinolook engages SGS to verify product quality at four stages — from refinery loading to your receiving tank — with full traceability of every batch.

CHECKPOINT 01

Shore tank inspection & sealing

SGS inspects the loading shore tank and seals it after passing.

CHECKPOINT 02

Pre-discharge re-inspection

SGS re-inspects on arrival before any product leaves the vessel.

CHECKPOINT 03

Pipeline cleaning verification

Discharge pipelines are cleaned and verified to prevent cross-contamination.

CHECKPOINT 04

Post-discharge tank report

SGS issues final quality reports after product enters bonded tanks.

Packaging & Logistics

Flexible delivery — from drum to bulk vessel

Bonded storage at Yingkou, Nantong and Guangdong in China; partner facilities in Singapore, Malaysia and other Asia-Pacific hubs. ISO tank, flexitank, drum and bulk options available.

In-house ASTM testing
