Why Oil Analysis for "Sealed" Spec Engines
Just like an engine dyno measures horsepower, used oil analysis measures engine wear without having to disassemble the engine. The use of “sealed” engines makes inspecting an engine anywhere from an inconvenience to illegal depending on series rules. Utilizing atomic emission spectroscopy, used oil analysis reveals the amount of wear occurring within an engine and reports it in parts per million of each element. As such, a “sealed” engine can be inspected without even needing to pull the engine out of the vehicle, and each SPEEDiagnostix report provides these details in plain English – no chemistry degree required!
Fortunately, used oil analysis does not stop at indicating wear metals. Used oil analysis also reveals contaminants such as water, coolant, fuel dilution and airborne dirt/sand. Contamination levels provide insight into the effectiveness of both oil and air filters as well as the tune up of the engine. High levels of fuel dilution indicate possible injector or carburetor problems, which are common with Ethanol blended fuels. Again, the SPEEDiagnostix reports highlight and provide guidance related to contamination in plain English.
Finally, used oil analysis provides trend analysis which reveals the “health trend” of the engine. When should the engine be rebuilt? Can the engine run another race? Trend analysis answers these questions and more. Once a normal level of wear and contamination for certain engines has been established, it becomes easy to spot potential problems early on before they become much bigger problems. Catching problems early saves time and money.
