Which system reduces engine-part wear from friction using oil?

Correct answer

Lubrication system

The lubrication system supplies oil to parts that need it to reduce friction and wear. The exhaust carries away gases and the silencer reduces noise; neither replaces that function. Maintain oil and changes according to the manufacturer. Proper lubrication helps prevent seizure but does not eliminate all wear or guarantee freedom from faults.
