What does the oil filter do?

• A. Removes solid contaminants from fuel
• B. Removes solid contaminants from engine oil
• C. Provides connection between engine and retract system
• D. 24 volt, used to start diesel engine

Answer: (B)

The main idea is that engine oil must stay clean to lubricate moving parts effectively. An oil filter removes solid contaminants from engine oil as it circulates. By trapping particles like metal shavings and dirt, the filter prevents wear and damage, helping the engine run smoothly and last longer. The other options describe parts of different systems: removing solids from fuel would be the job of a fuel filter; connecting the engine to a retract/ hydraulic system is unrelated to filtration; and a 24-volt starter relates to the electrical starting system, not oil filtration.
