• Viscosity

• Cooling

• Ability to pick up metal in the system

Which of the following is an advantage to using thinner engine oil?

• Lubricates the engine better

• Doesn't slip past oil rings as much as a heavy oil

• improved protection at higher temperatures

• Improved fuel economy

Which of the following is an advantage to using thicker oil?

• Improved starting in cold weather

• Improved fuel economy

• Improved protection at higher temperatures

• Less frequent oil changes needed

The viscosity rating is sometimes printed on the __________________________ under the hood.

• Oil Cap

• Emission Sticker

• Valve Cover

• Dip Stick

The major advantage to using synthetic oil is:

• Synthetic oil is cheaper

• None of the above

What is the advantage of using an oil filter with an anti-drain back valve?

• It allows the engine to receive immediate lubrication as soon as the engine starts
