100

This is the main purpose of engine oil in reducing wear between moving parts.

What is lubrication (reduces friction)?

100

This type of oil has a consistent molecular structure and high durability.

What is synthetic oil?

100

0W-20 is an example of this type of oil rating system.

What is SAE rating?

100

EVs have this compared to ICE vehicles in terms of moving parts.

What is fewer moving parts?

100

This system tells drivers when it’s time to change oil.

What is an oil life monitoring system?

200

This term describes gas leaking past piston rings into the crankcase.

What is blow-by?

200

This oil type is a blend of synthetic and conventional oils.

What is semi-synthetic or synthetic-blend oil?

200

SP is an example of this oil classification system.

What is API rating?

200

EV fluids are typically made with this type of base oil.

What is synthetic base?

200

Normal oil change intervals typically fall within this mileage range.

What is 7,500–10,000 miles (normal service)?

300

This is one major function of oil besides lubrication (hint: temperature control).

What is cooling (heat dissipation)?

300

These additives keep contaminants suspended to prevent sludge.

What are dispersants?

300

The “W” in 0W-20 stands for this condition.

What is winter (cold temperature rating)?

300

This property prevents electrical current leakage in e-fluids.

What are dielectric properties?

300

After the oil filter gasket contacts the engine, it should be tightened this much.

What is 3/4 to 1 full turn?

400

This happens when oil helps remove contaminants from engine components.

What is cleaning?

400

These additives prevent oil from thinning at high temperatures.

What are viscosity modifiers?

400

dexos1 is an example of this type of specification.

What is manufacturer specification?

400

This type of lubricant is used for EV wheel bearings under extreme conditions.

What is e-grease?

400

Oil labeled “Resource Conserving” is designed to improve this.

What is improved fuel economy?

500

This engine condition occurs when oil pressure is low and requires immediate shutdown.

What is low/no oil pressure condition (engine damage risk)?

500

This type of oil is refined directly from crude oil.

What is conventional (mineral) oil?

500

These organizations develop and identify standards for engine oils (two answers).

What are ILSAC and API?

500

These specialized EV fluids are used for managing temperature instead of traditional coolant.

What are e-thermal fluids?

500

This is the first action you should take if the oil warning light indicates no pressure.

What is shut off the engine immediately?
