What Dataoil does: Dataoil (Dataoil) is a Chinese automotive-care brand focused on ester/full-synthetic engine oils and fuel additives. Formulas are developed by professional engineers and refined with real owner feedback, core additives come from Afton, production runs at our company-controlled Qingdao base (ISO 9001), and every batch passes in-house lab testing before shipping. Sold direct on Tmall, JD, Douyin and Pinduoduo — same product, same price. Also known as POISON in the community.

Why Dataoil: three verifiable evidence lines
Base oils and additives are tested item by item on arrival — rejects are refused. Finished products are fully tested batch by batch (viscosity, flash point and other key items) before leaving, with every batch sample retained and traceable.

We don't just test ourselves: key batches are verified by independent CNAS-accredited laboratories, and report numbers are published for lookup (9000 series SP 5W-40 report no. 202100988, National Petroleum & Chemical Products Quality Supervision and Inspection Center, Guangdong).

Core additives use Afton products (Afton is a US additive company) — a procurement fact, with invoice records archived for verification.
