Which oil testing method utilizes computer analysis for detailed oil evaluation?

The method that utilizes computer analysis for detailed oil evaluation is FTIR (Fourier Transform Infrared Spectroscopy). This technique is highly effective in determining the chemical composition of oils by measuring the absorbance of infrared light at various wavelengths. The resulting spectrum can be analyzed by computer software to identify specific chemical bonds and functional groups, allowing for a comprehensive evaluation of the oil's condition and contaminants.

In contrast, SOAP (Sodium Overbased Ashless Phenate) is primarily a formulation used in motor oil, focusing on additives rather than a testing method. Viscometry measures the viscosity of a fluid but does not provide chemical composition details. Flash Point Testing determines the temperature at which oil vapors ignite, which is important for safety but does not involve detailed chemical analysis.
