Oil and fluid testing answers both short- and long-term questions about the internal condition of engines, transmissions and hydraulic systems.

A one-time sample of engine or transmission oil gives a “snapshot” look at what’s going on inside. The presence of water or high levels of silica, bronze or other metals suggests there might be problems with a leaky head gasket, a damaged engine air filter or problems with internal bushings. Identifying potential problems allows preventative repairs rather than waiting for actual breakdowns.

Ongoing oil sampling allows predictive maintenance and repairs. Most companies that analyze oil samples can create a database for customers that tracks the levels of various contaminants and worn particles over time. If a semi-annual or annual oil test indicates rising levels of silicates, then dust might be getting into the intake air system. Increasing levels of bronze suggest bushing problems somewhere inside the machine. Rising levels of chromium might indicate excessive ring or cylinder wear. Monitoring oil condition over time allows predictive repairs rather than repairs as a result of a breakdown.

Another benefit of regular oil sampling comes when it’s time to trade or sell the machine. Showing prospective buyers a long-term report indicating no unusual changes in engine oil samples builds confidence that can lead to higher sale prices.
