We have been sourcing CI-4 diesel engine oil and MoS2 lithium grease from Runyuan Shengchi for our mining fleet for over three years. The products perform reliably under extreme dust and heavy shock loads, and their factory-direct pricing and stable supply have significantly reduced our operating costs.

As an OEM partner, we needed a manufacturer who could develop custom hydraulic oil and gear oil formulations to our own specifications. Runyuan Shengchi delivered on time, met API and SAE standards, and supported us with full export documentation. A truly reliable one-stop lubricant supplier.

Our transport fleet runs long-haul routes in high temperatures. Since switching to their CI-4 diesel engine oil and GL-5 85W-90 gear oil, we have extended drain intervals, reduced wear on transmissions and cut maintenance downtime. Their service team is always responsive and professional.

We distribute lubricants for agricultural machinery across our region. Their CF-4 diesel engine oil, lithium grease and transmission oil have become best-sellers because farmers trust the consistent quality. The factory-direct supply and flexible MOQ make them an ideal long-term partner.

We launched our own lubricant brand with their OBM service. From formulation and packaging design to labeling and export paperwork, Runyuan Shengchi handled everything. The products meet ACEA and API standards and our customers are very satisfied with the quality.

For our construction equipment we use their L-HM46/68 anti-wear hydraulic oil and GL-5 gear oil. Even on dusty sites with continuous operation, the hydraulic systems stay clean and responsive. The quality is stable batch after batch, which is exactly what we need from a supplier.
