Reduces friction means increased efficiency

Explanation:

Friction is known to decrease efficiency in machines. In redesigning the engine if the antique car, and the inclusion of oil to reduce friction in the engine, she aims to improve the efficiency of the engine.

Friction leads to lost work in mechanical systems. Friction accounts for the fact that the efficiency of an engine is never 100% since some of the input work is lost as friction.

Hence decreasing the friction improves the efficiency of the machine.
