Engine oil
Engine oil consists of a base oil mixed with different additive components and its main function is to prevent wear and tear to the engine by greasing, cooling, cleaning and protection against corrosion.
Motor oils are generally added 20-25% of volume with additives. these substances are typically anti foam, antioxidants, antiwear, cleansers, solubilizers and viscosity enhancers.
Analysis:
An analysis of engine oil should reveal wear metals, contamination or additive elements plus chemical and physical properties of sample.
By comparing the these values with new oil and/or previous samples from the same systems we are able to form a opinion of the current state.
