Q

A diesel engine should use which type of lubricating oil?

🔍 Key Concepts

• Differences between diesel engine lubricating oil and general-purpose oils • Purpose of detergents and additives in modern engine oils • Why some oils (like vegetable or cutting oils) are unsuitable for high‑temperature, high‑pressure engines

💭 Think About

• Think about the conditions inside a diesel engine: high temperature, soot, combustion by‑products. What properties must the oil have to keep the engine clean and protected? • Which option sounds specifically designed for internal combustion engines, rather than for machining tools or cooking? • Which oil type can suspend carbon and sludge so they can be carried to the filter rather than building up on engine parts?

✅ Before You Answer

• Eliminate any choices that are clearly not used inside engines (what are they normally used for?). • Consider which oil type is formulated to keep deposits from sticking to pistons, rings, and valves. • Ask: Which option would a manufacturer specify for modern diesel and gasoline engines in vehicles and vessels?
