I couldn't find a thread for this in the HDEO section so I wanted to start one. I suppose it would be good for anything using HDEO including gasoline engines where it is being used. I'll start with my most recent:
2000 Mack DM690S Dump truck, unknown interval
Out: Unknown oil, Mack filters
In: 8 gallons Schaeffer 15w40, 1 gallon Schaeffer 132 oil treatment, 2x Mack 21939298 full flow filters, 1x Mack 85136709 centrifugal filter
Next interval will be 250 hours. I will pull a sample at that OCI and see what it shows. Hoping for 500 hours on this combination.
