The 4L CI-5 10W-40 Diesel Engine Oil from Chongqing Huifan Technology Co., Ltd. is a synthetic-blend lubricant engineered for modern diesel engines operating under high loads and varying temperatures. It meets the API CI-5 specification, which is designed for engines with advanced emission control systems, including those equipped with diesel particulate filters (DPFs) and exhaust gas recirculation (EGR). The 10W-40 viscosity grade ensures stable performance across a wide temperature range, from cold starts to high operating temperatures.
This oil is formulated with a balanced additive package to provide superior thermal stability, oxidation resistance, and shear stability. Typical industry benchmarks for CI-5 oils include a flash point above 200°C, a pour point below -20°C, and a TBN (Total Base Number) of 8 - 12 mg KOH/g to neutralise acidic combustion byproducts. The synthetic components reduce friction and wear, improving fuel efficiency and extending engine life in heavy-duty applications.
The product is suited for heavy-duty trucks, construction equipment, and industrial diesel generators. Buyers in logistics, mining, and agriculture rely on CI-5 oils to maintain engine performance in harsh conditions. Chongqing Huifan Technology Co., Ltd. packages the oil in 4L containers, with bulk options available for fleet operators. Confirm the supplier’s ability to provide consistent batches with verified API certification before committing to large orders.

Before ordering, verify that the oil meets the API CI-5 specification and is suitable for your engine’s make and model. Request a certificate of compliance and batch test reports from Chongqing Huifan Technology Co., Ltd. to confirm the oil’s additive package, viscosity, and TBN. For fleets, consider conducting a field trial to assess performance in your specific operating conditions.
Clarify logistics details, including packaging, shipping terms, and lead times. The 4L containers are standard for retail and small-scale buyers, but bulk buyers should confirm whether the supplier offers IBC totes or drum packaging for larger volumes. Incoterms such as FOB Chongqing or CIF to your port should be negotiated based on your import requirements and preferred payment methods.
Quality checks should include laboratory testing for viscosity, flash point, pour point, and TBN to ensure consistency with the supplier’s specifications. For critical applications, request third-party testing to validate performance in areas such as oxidation stability, shear stability, and compatibility with emission control systems. Always retain samples from each batch for future reference.
