Re: sythetic oil OK, what does the result of the test tell us?STANDARD ANALYSIS Blackstone's standard analysis will tell you what you need to know about the condition of your engine and how it's wearing. The standard analysis costs $22.50 and includes the following: Spectral Exam: Establishes the levels of wear metals, silicon, and additives present in the oil. Also checks for coolant. Viscosity: Determines the grade of oil. Insolubles: Quantifies the percentage of solids present in the oil. Flash Point: Determines the flash point of the oil. We use the flash point to determine whether any contamination is present in the oil (determined when the flash is lower than the "should be" range). Inquiring minds want to know!
