Import 1l Cj-4 5w-30 Diesel Engine Oil — Buy in wholesale FOB from Supplier in China

This 1-litre bottle of CJ-4 5W-30 diesel engine oil from Chongqing Huifan Technology Co., Ltd. is a fully formulated lubricant designed for modern diesel powertrains. The CJ-4 API service category indicates it meets the demands of 2007 and later emission-controlled diesel engines, while the 5W-30 viscosity grade provides reliable cold-start flow and stable protection at operating temperature. The formulation incorporates high detergent properties to combat sludge and soot buildup, alongside enhanced oxidation resistance to maintain oil integrity over extended drain intervals.

The 5W-30 viscosity is common across heavy-duty and light-duty diesel applications, offering a balance between fuel economy and wear protection. Typical industry specifications for CJ-4 oils include total base number (TBN) values above 7.0 mg KOH/g for acid neutralisation, sulphated ash content below 1.0% to protect diesel particulate filters, and phosphorus levels controlled to around 0.12% to safeguard catalytic after-treatment systems. This oil's thermal stability supports consistent performance in high-temperature operating environments, a key requirement for engines under sustained load.

Primary buyers include fleet operators, agricultural machinery owners, and workshops servicing heavy-duty trucks, pickups, and construction equipment. The 1-litre packaging is suitable for top-ups, smaller engines, or retail resale.
