Diesel engine oil
Diesel engine oil CF-4 20W50 4L*6PCS
High anti-wear protection: Compliant with CF-4 specification, it can effectively reduce the wear of key engine components such as pistons and crankshafts, extend the engine's service life, and is especially suitable for diesel engines operating under high loads.

Features
Excellent high and low temperature adaptability: "20W50" is a multi-grade viscosity rating. It can start smoothly at around -15℃ (its low-temperature fluidity meets the 20W standard), and maintain a stable oil film at high temperatures (such as the normal operating temperature of the engine), avoiding insufficient lubrication due to thinning of the engine oil. Strong oxidation resistance and cleaning ability: It can inhibit the high-temperature oxidation and deterioration of engine oil, reduce the formation of sludge and carbon deposits, keep the engine interior clean, and lower the risk of oil passage blockage caused by impurities. Anti-corrosion and sealing protection: It can resist the corrosion of engine metal parts by combustion products (such as acidic substances), and enhance the sealing performance of oil seals, reducing oil leakage.
Application
Vehicles/equipment that have been operating under high loads for a long time (such as fully loaded freight trucks, frequently operating construction machinery).
Regions with high ambient temperatures (such as southern summers), or scenarios where engine temperatures are prone to rise (such as prolonged uphill driving).
Applicable engine oil grade requirements: Only suitable for engines that require engine oil of "CF-4" grade or lower. Not suitable for engines that require higher grades (such as CH-4, CI-4) and meet or exceed National IV emission standards.

Grease Usage Notice
Do not mix different grades of engine oil: It is strictly prohibited to mix with other viscosities (such as 15W40) or grades (such as CH-4) of diesel engine oil. Otherwise, it will damage the performance of the engine oil and may lead to engine lubrication failure.
Does not meet the requirements of high-emission engines: CF-4 20W50 must not be used in diesel engines with emission standards of National IV and above (which require CH-4 or higher grade engine oil). Otherwise, it will fail to meet the lubrication and emission requirements of the engine and may cause faults or accelerate wear.
