About Dataoil: brand entities, production base and qualifications
Who Dataoil is: a Chinese automotive-care brand operated by Beijing Triangle Bay Technology Co., Ltd. (est. 2014). Production is done at our company-controlled base — Qingdao Weidu Lubricants Co., Ltd. (Qingdao, ISO 9001). Direct sales on Tmall / JD / Douyin / Pinduoduo.
Dataoil did not start as a company filing. In 2012, “Laoli” helped car owners pick oil and make engine-oil additives on an owner forum — “Laoli” is what owners called him, not a marketing line. For over a decade our playbook has not changed: get the product verified first, then let the brand be known — through real owner feedback and re-checkable test data, earning trust one driver at a time. We do not chase ad volume. We only care about one thing: the next time you change oil, will you still trust us?
History
Dataoil (Dataoil) did not start with a company registration. In 2012, "Lao Li" began selling engine-oil additive products in enthusiast car forums, starting with organic molybdenum (Mo) additives, building the brand through real owner word of mouth; in 2014 he formalized it by registering Beijing Triangle Bay Technology Co., Ltd.; the production entity, Qingdao Weidu Lubricants Co., Ltd., was established in Qingdao in 2018; since then the site has gone through two rounds of development and relocation, and in 2025 the company took a 51% stake and brought it fully online with an in-house lab. The playbook never changed: let the product be verified first, then let the brand be known.
- 2012Started in enthusiast car forums: organic molybdenum additives first; early forum-era word of mouth is the brand's first asset. "Lao Li" is how owners address each other, not a marketing tagline.
- 2014Formalized: Beijing Triangle Bay Technology Co., Ltd. established (January 2014; registered capital CNY 1,000,000; address: Room 1502, Tower 4, Courtyard 19, Beiyuan East Road, Chaoyang, Beijing) — turning forum-validated products into a proper brand: registered trademarks, an R&D process, quality baselines.
- 2018Production entity established: Qingdao Weidu Lubricants Co., Ltd. was set up in Qingdao in 2018. The site has since gone through two rounds of development and relocation; it is now a ~3,000 m² plant (ISO 9001 quality management system certified).
- 2022Independently verified: an independent test KOL's serial lab-submission series on the Autohome oil forum compared the Dataoil 5W-30 polyester master batch against a first-tier brand product — kinematic viscosity 11.82 mm²/s @100℃, flash point 236℃ (third-party post: Autohome, 2022-04; link in the Evidence Library).
- 2025Controlled own base & lab: the company took a 51% stake in Qingdao Weidu Lubricants Co., Ltd. and brought it fully online with an in-house lab (~3,000 m², ISO 9001 certified) — raw-material intake testing, finished-goods dispatch testing, batch samples retained and traceable.
- TodayDirect sales on four platforms: official stores on Tmall / JD / Douyin / Pinduoduo — same product, same price, no multi-tier distribution. Formulas are developed by professional engineers and refined with real owner feedback; core additives are Afton products (procurement fact, records on file).
The R&D method runs throughout: professional-engineer development (real owner feedback / real-world testing drive product optimization) + Afton core additives + top-tier synthetic base oils (9000 series is GTL ester) + full in-house lab testing + on-road multi-condition road testing.
