Final answer:

Understanding the importance of choosing the right viscosity oil or additive like ZDDP for engine lubrication in older engines is key to engine maintenance and performance.


Explanation:

Viscosity is a crucial property of motor oils, described by SAE ratings that range from low to high viscosity. In the context of an older engine with flat-bottom lifters, the correct choice to ensure proper lubrication would be an oil or oil-additive containing ZDDP (zinc), as ZDDP helps protect the engine's metal components by forming a protective layer. Using the wrong viscosity oil or additives can have detrimental effects on engine performance and longevity.
