Proper fluid maintenance is imperative to keep equipment operating at peak performance. Yancey’s Scheduled Oil Sampling Fluid Analysis is the only lab in Georgia that compares wear elements in your oil to hundreds of other machines. We analyze your used fluids and identify problems before they grow into major repairs. Combined with our knowledge of Caterpillar products, we provide you concise interpretive reports. Our technicians are available to answer any questions on fluid analyses and will discuss report-specific recommendations and readings. Our fluid readings will help you plan for downtime to fit your workload and maintain your bottom line.

The ability of a fluid to maintain appropriate film thickness at high temperatures.
A test for the presence of contaminants that may increase wear. Usually expressed in an ISO code.
A normal process that occurs in oil as it ages and combines with oxygen molecules. Oxidation causes increased viscosity, acid formation, and deposits.
As sulfur from fuel combines with water during the combustion process, sulfuric acid forms. Engine oil neutralizes this acid and is measured as sulfation. Lubricant degrades, and internal parts can corrode if sulfation reaches an unacceptable level.
Soot is the insoluble residue of partially burned fuel and causes wear. Its adverse effects are minimized if it’s held in suspension by addition in engine oil. However, excessive levels will eventually overpower the additives. When this occurs, the soot will drop out of suspension, and wear will accelerate.
Low viscosity can occur if fuel dilution is left unchecked. If the oil film does not have adequate thickness, moving parts may experience direct contact that results in scuffing or seizure.
Water can be the result of condensation, leaks, pressure washing, or other means. When water is present, it causes corrosive wear and rusting.
Engine oil can become contaminated with coolant due to leaks from oil cooler cores, internal coolant passages, and cylinder head gaskets. Other compartments using coolant to oil coolers become contaminated when the coolers leak, creating contamination and sludge.
