The Science Behind Our SP 10W/30 Gasoline Engine Oil

In the world of automotive maintenance, trust is earned, not given. When you pour a bottle of oil into your engine, you are entrusting the heart of your vehicle to a complex chemical formulation. But how can you be sure that the oil meets the high standards promised on the label? At Leanon Petroleum, we believe that transparency and scientific rigor are the foundations of quality. Our SP 10W/30 Gasoline Engine Oil is not just blended; it is engineered with precision, backed by state-of-the-art technology, and validated by some of the most stringent quality control measures in the industry.
 

The journey of our SP 10W/30 Gasoline Engine Oil begins long before it reaches a bottling line-it starts in our Research and Development Center. We have invested heavily in our technical capabilities, establishing a laboratory that operates at the highest level of scientific standards.

Our facility is proud to hold CNAS (China National Accreditation Service for Conformity Assessment) certification. This is not merely a badge; it is an international recognition of our technical competence. It signifies that our testing data is accurate, reliable, and recognized globally.

Inside this lab, our team of expert chemists and engineers conduct over 60 different types of testing. From analyzing viscosity and flash points to measuring total base number (TBN) and cold cranking simulator (CCS) performance, every batch of SP 10W/30 Gasoline Engine Oil undergoes a comprehensive health check. This ensures that the oil leaving our facility performs exactly as intended, providing consistent protection every time.

Quality lubrication is a global language. To ensure our products meet the diverse needs of international markets, we have cultivated strategic partnerships with the world's leading additive companies, including Lubrizol, Infineum, Chevron Oronite, and Afton. These "Big Four" additive manufacturers provide the cutting-edge technology that goes into our formulations.

By combining their advanced additive packages with our deep understanding of engine mechanics, we create a SP 10W/30 Gasoline Engine Oil that is optimized for modern engines. Whether it is meeting the latest API SP requirements for preventing low-speed pre-ignition (LSPI) or ensuring compatibility with emission systems, our formulation process is guided by international benchmarks. We don't just follow standards; we aim to exceed them.
 

Consistency is the hallmark of a great product. A bottle of oil bought today must perform exactly the same as a bottle bought next year. To achieve this, our manufacturing processes are certified under IATF 16949, the international standard for automotive quality management systems.

This certification dictates how we manage every aspect of production:

• Automated Blending: We utilize fully automated blending systems that ensure the precise ratio of base oil to additives, eliminating human error.
• Dedicated Lines: Our "dedicated pipe" system prevents cross-contamination between different oil grades, ensuring the purity of our SP 10W/30 Gasoline Engine Oil.
• Traceability: Every step of the process is monitored and recorded, allowing us to trace the history of every batch produced.

Leanon Petroleum is more than a factory; we are a "Specialized, Refined, Differential, and Innovative" (SRDI) enterprise. This designation recognizes our commitment to focusing on specific market niches and driving technological advancement. Our team, with an average age of just 34, brings fresh energy and a commitment to continuous improvement.

When you choose our SP 10W/30 Gasoline Engine Oil, you are benefiting from a legacy of innovation. You are choosing a product that has been scrutinized by advanced spectrometers, tested in high-performance engines, and manufactured with automotive-grade precision.
