Which supply class includes Petroleum, oils, and lubricants?

• A. Class II
• B. Class III
• C. Class IV
• D. Class V

Answer: (B)

In this system, items are grouped into supply classes to organize procurement and management. Petroleum, oils, and lubricants belong in Class III, which is the category that covers fuels and lubricants used to power and maintain equipment. That’s why POL items like gasoline, diesel, lubricants, and hydraulic fluids are placed together in Class III.

Other classes map to different types of items: Class II covers clothing and individual equipment, Class IV is construction materials, and Class V is ammunition. So Class III is the best fit for petroleum, oils, and lubricants, distinguishing them from subsistence (Class I), clothing (Class II), construction materials (Class IV), or ammunition (Class V).
