For a dual-purpose vehicle, the engine oil must be heated to at least 220 degrees Fahrenheit in order to burn off all of the deposits and water vapor that has accumulated. When you burn a pound of fuel in an engine, the combustion process also generates one pound of water! As long as temperature in the engine sump does not rise above 212 degrees Fahrenheit (water’s boiling point), the water will combine with Sulphur (another combustion by-product) to form acids that can eventually damage bearings.

In terms of ultimate power potential, the general consensus among racers is that hot oil and cool water produce more power in the vast majority of engine configurations. Extreme frictional drag on the bearings and cylinder walls occurs when the engine oil is too cold. When exposed to oil sump temperatures of up to 250 degrees, a quality conventional motor oil will not break down, but it will begin to break down at temperatures above 275 degrees. According to tradition, oil temperatures should be maintained between 230 and 260 degrees Fahrenheit. The oil temperature should not be below 200 degrees Fahrenheit on a short-duration drag-only combination where the oil is changed on a regular basis.

There are some oval track race teams testing ultra-thin, specially formulated synthetic oils that can withstand temperatures as high as 350 degrees or even higher than typical full synthetic oils that can tolerate sump temperatures above 300 degrees.

Also keep in mind that a high-end engine is constructed as a complete system combination. Dimensions such as piston to wall clearances, piston ring end gaps, and bearing clearances are all tailored to the characteristics of the engine oil as well as its intended operating temperature to ensure proper performance.

Thermal breakdown is one of the most harmful effects, and it occurs when the internal heat of a car causes a chemical reaction in the motor oil, causing the viscosity of the oil to change. Simply put, if precisely, when the engine temperature rises above a certain point, the motor oil begins to degrade.
