Be sure to follow the directions thoroughly in filling out the request form and obtaining the oil samples. Analysis for wear metal concentration can be evaluated and wear rates determined only if all pertinent information necessary for analysis is available. To help us better evaluate your vehicles’ used oil, the request sheet must be accurately completed. Only with all of this information can precise determinations of wear rates be made. Since concentrations of suspended materials are not necessarily the same throughout the lubricating system, proper sampling techniques must be employed (sampling instructions are provided on the back of the request form). In fact, improper sampling procedures can lead to misleading results. For more information please visit our web site at www.napafilters.com. 1065
