This filter came off of a ThermoKing APU with a Yanmar 2 cylinder diesel engine. It was on there since September 20, 2020, so about 3.5 years. The filter accumulated exactly 300 hours of run time. The engine has 15,651 hours.
This APU was underneath my truck all over the US from Miami FL over 100 degrees in the summer to Michigan winters way below 0, and snow and salt all over the place. No wonder the outside is a little rusty. Filter was made on March 1, 2017.
Out: this filter and Rotella T6 5W-40.
In: Fram HM3593A and Mobil Delvac 15W-40.
Remember those brown high mileage fram filters? Got it for $1 years ago when Walmart discontinued them.
