Why Oil Analysis for Classic Car Owner

 

Just like a yardstick measures length, used oil analysis measures wear. Similar to a doctor taking a blood sample, used oil analysis provides a “health report” on the equipment the sample was taken from without having to open up the equipment. For classic cars, used oil analysis documents the health of the engine, transmission and rear gear. 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, increasing levels of tin and lead indicate bearing wear. High levels of aluminum indicate piston scuffing, 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, anti-freeze, fuel dilution and airborne dirt/sand. Contamination levels provide insight into the tune up of the engine. High levels of fuel dilution indicate possible 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? Trend analysis answers this questions and others. 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.
