What type of oil is used in a single-cylinder diesel engine?
2 Answers
Single-cylinder diesel engines use CD or CF grade oil, with viscosity options such as 10W-30, 15W-40, or 20W-50. The oil grade should be selected based on the diesel engine's load and working environment. Relevant information about engine oil is as follows: Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a vehicle. Composition: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, while also imparting certain new characteristics, making them an essential part of lubricating oil.
I'm quite familiar with engine oil for single-cylinder diesel engines. Commonly, 20W-50 mineral oil with CF-4 or CH-4 specifications works perfectly. These machines operate at low RPM with heavy loads, requiring higher viscosity oil to form a protective film for cylinder liners and pistons. I've seen people try to save money by using gasoline engine oil, only to end up with cylinder scoring within two or three months, accompanied by black smoke and power loss. Remember, the oil change interval shouldn't exceed 200 hours or six months, and the old oil in the gearbox must be completely drained before adding new oil. For cold starts in northern winters, switching to 15W-40 winter-specific oil is advisable. During maintenance, it's best to replace the filter element as well. Every time I change the oil, I make it a habit to check the oil pan screws - any oil seepage should be addressed promptly.
