What's it all mean???

With all the numbers and letters and codes and grades in this business, it's a wonder anyone can keep anything straight. Here's a little quiz to double-check your knowledge of all this classification alphabet soup. Give it a shot just for fun.

1. Many oils are identified by two numbers (i.e., 10W-30). Such oils are referred to as:
a. bi-numeral oils
b. two-number oils
c. multigrade oils
d. confused oils

2. Oils identified by two numbers tell us:
a. the oil has two viscosities, performing well in both high and low temperatures
b. a car using that oil should be driven only in temperatures ranging from the lowest to the highest number (10W-30 between 10 F and 30 F).
c. absolutely nothing. Years ago, some engineers started referring to oils this way to see if anyone noticed.

3. For most passenger cars and light trucks driven under typical driving conditions, the motor oil should be changed:
a. every 1500 miles
b. every 3000 miles
c. every 5000 miles
d. never

b. The Donut
c. The Merit Badge
d. The Red Badge of Courage

5. ILSAC GF-2 is the most technically advanced motor oil standard in the world for most U.S. and Japanese cars.
a. True
b. False

6. ILSAC stands for:
a. The Institute of Lubricant Standards Advisory Council
b. Installation and Lubrication Society of American Carmakers
c. International Lubricants Standardization and Approval Committee

7. SAE stands for:
a. Society of Automotive Engineers
b. Standard Association of Engineers
c. Sigma Alpha Epsilon

8. API stands for:
a. American Petroleum Institute
b. Association of Petroleum Installers
c. Another Petty Identification

9. Are you tired of all these acronyms?
a. Yes
b. No
c. Don't care
d. What's an acronym?

10. The leader in lubrication technology and the first motor oil to meet new, tougher GF-2 standards for protection is:
a. Pennzoil
b. Pennzoil
c. Pennzoil
d. If you thought it was somebody else, you automatically fail this test.
