Which information do you get by an ANAC diagnosis ?
Every engine part will wear under operation, even when correctly lubricated. This wear generates very small metallic particles ( a few microns in size) which are captured by the lubricant and kept in suspension.
Every engine part has its own metallurgical concept and therefore the kind of metal(s) identifie(s) the wearing engine part, and the concentration of the metal in the oil ( measured in ppm = mg metal per kg oil ) indicates the wear rate.
The ANAC database, established on a history of over 3 million previously performed oil analyses, contains references of the typical wear metal values for all engine types.
ANAC compares the wear values measured in your sample with the database references of your engine type and assesses if the wear rate is normal or indicates a problem which needs to be solved in order to prevent damage. An increase of the engine wear very often finds its cause in the presence of contamination elements : water, cooling liquid, fuel, dust, soot,…
These contaminants are also measured in the ANAC lab, as well as the viscosity of the oil, which can be influenced by these elements. Finally, a clear comment by an ANAC Expert on engine and lubrification summarizes the diagnosis and gives you advice on interventions if needed. |
