Q:

How many quarts of oil are used in engines for NASCAR racing?

A:

According to Race Line Central, a NASCAR engine holds 16 quarts of oil. Unlike regular cars, race cars have a dry pump lubrication system, according to Popular Mechanics.

In a race car, oil is immediately pumped to an external tank, as this keeps the oil cool and free of air bubbles. Racing oil has a thin, water-like consistency, and it does not have the same additives found in regular motor oil. For example, oil for passenger cars has anti-corrosion additives to protect the engine parts between oil changes. Race cars get new oil prior to each race, so these additives are not necessary, states Popular Mechanics. Motor oil companies keep the specific formulas for racing oil highly guarded to prevent other companies from reverse engineering and stealing the formulas, according to the Wall Street Journal.
