Why Oil Analysis for Engine Builders

Just like a dial caliper measures allows you to measure parts, used oil analysis allows you to measure engine wear without having to disassemble the engine. 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.

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.

Accordingly, used oil analysis provides engine builders with the ability to document the health of an engine before delivering the engine to the customer. By taking a used oil sample following break-in on the dyno or run-in stand, the health of the engine and contamination level can be documented. This documentation also provides a reference point for future samples – from either the same engine or from similar engine builds. 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 everyone time and money.
