These values are typical for the engines described above. These are only guidelines and the wear rates for a particular engine should be determined by a trend established by a number of samples on that engine. Engine wear rates on your engines may differ from the rates listed above due to application, or model of engine. Based on a 12,000 to 15,000 mile drain interval.
