Lubrication System Quiz

What is the primary purpose of a lubrication system?

• To increase friction

• To absorb shock

• To cool the engine

• To lubricate and reduce friction

What does the oil help to seal in the lubrication system?

• Oil galleries and oil pan

• Piston rings and cylinder walls

• Oil filter and oil pump

• Crankshaft and bearings

What happens if the oil is too thin?

• It flows too slowly

• It will be forced out from moving parts

• It cools the engine effectively

• It absorbs too many contaminants

What is viscosity a measure of?

• Oil's temperature

• Oil's resistance to flow

• Oil's ability to absorb shock

• Oil's cleaning properties

What does a high viscosity oil do?

• Cools the engine quickly

• Flows easily

• Thins out when heated

• Flows slowly

What is the purpose of the oil filter?

• To absorb shock

• To cool the oil

• To filter out contaminants

• To increase oil pressure

What is the recommended oil change interval?

• Every 2000Km

• Every 10000Km

• Every 5000Km

• Every 1000Km

What does the oil pressure indicator do?

• Cools the oil

• Filters the oil

• Measures oil temperature

• Indicates low oil pressure

What is the function of the pressure relief valve?

• To filter contaminants

• To prevent high pressure buildup

• To cool the oil

• To increase oil pressure

What is a common cause of low oil pressure?

• Worn out pump

• Cold engine

• New oil filter

• High oil level
