Understanding Engine Lubrication Basics

What is the primary function of engine oil in a vehicle?

• To cool the engine

• To lubricate engine components

• To clean the engine

• To fuel the engine

Which of the following is a type of engine oil commonly used in modern vehicles?

• Mineral oil

• Synthetic oil

• Vegetable oil

• Olive oil

What component in the lubrication system is responsible for filtering out impurities from the engine oil?

• Oil pump

• Oil filter

• Oil pan

• Oil cooler

How does oil viscosity affect engine performance in cold weather?

• Higher viscosity oils flow better

• Lower viscosity oils flow better

• Viscosity has no effect

• Viscosity only affects fuel consumption

Which of the following is NOT a component of the engine lubrication system?

• Oil pump

• Radiator

• Oil pan

• Oil filter

What is the typical unit of measurement for oil viscosity?

• Litres

• Pounds

• Centipoise

• Degrees Celsius

What is the main advantage of using synthetic oil over mineral oil?

• Cheaper cost

• Better performance at extreme temperatures

• More environmentally friendly

• Easier to dispose of

Which component of the lubrication system helps in cooling the engine oil?

• Oil filter

• Oil cooler

• Oil pump

• Oil pan

What does the term "multi-grade oil" refer to?

• Oil that can be used in multiple types of engines

• Oil that has additives for cleaning

• Oil that has varying viscosity at different temperatures

• Oil that is environmentally friendly

What happens if the engine oil viscosity is too high for the engine?

• It improves fuel efficiency

• It can cause increased engine wear

• It reduces engine noise

• It enhances engine power
