Import Diesel Engine Oil — Buy in Bulk from Supplier in China

Diesel engine oil from Zhengzhou Dongshen Petro-Chemical Technology Co., Ltd. is formulated as a nano-alloy polymer-based additive blend designed to enhance lubrication and reduce friction in internal combustion engines. It is not a standalone lubricant but a performance additive to be mixed with conventional diesel engine oils. The product claims to reduce fuel consumption by 5% to 25% and engine wear by 80% to 90% through dynamic surface repair mechanisms, as described in patent ZL200810032849.1. It is supplied in boxed packaging and can be customized for bulk orders.

The formulation contains multifunctional additives and nano-particles engineered to bond with metal surfaces, repairing micro-wear and reducing friction coefficients. It is marketed as compatible with all diesel engines in passenger vehicles and light commercial fleets, and it does not alter the base oil's viscosity grade. Industry-standard SAE 15W-40 or 10W-40 base oils are typically used as carriers for such additives. The product is not certified to API CK-4 or ACEA E9 standards, and no third-party lab validation is provided in the source data.

This additive is primarily sourced by fleet operators in emerging markets seeking to extend oil drain intervals and reduce maintenance costs. Buyers typically order in bulk, with packaging options including 1L, 5L, or 20L containers. It is shipped in standard cartons and requires no special handling. The supplier does not specify minimum order quantities, lead times, or Incoterms. Buyers should confirm compatibility with their existing engine oil and request test reports for wear reduction claims before large-scale adoption.

Zhengzhou Dongshen Petro-Chemical Technology Co., Ltd. is based in Zhengzhou, Henan Province, China, with a registered address at Room No.0508, No.16 Zijingshan Road. The company is listed as an imported supplier with harbor-tier trust verification, indicating it has completed basic identity and address validation. There is no public information on years in operation, annual production volume, or client list. The supplier does not display response rate or average reply time, suggesting limited active engagement with buyers on the platform.

The company’s product focus is on proprietary chemical additives for engine performance, centered around its patented nano-alloy technology. It does not claim to manufacture base oils but instead produces additive concentrates. There is no mention of ISO certification, laboratory testing facilities, or export experience beyond this single product listing. Buyers should treat this as a niche technology supplier with limited public transparency, and verify claims independently before procurement.
