Metal in oil

I would call my driving spirited
Once in a while I get on it hard but mostly baby it
I use an oil pan heater when below 60 degrees to warm oil
Mostly trips under 10 miles with a good 2-3 minutes warm up in drive way at idle
I’m 67 and pretty conservative driver
Never heavy throttle over 3500 RPMs
Occasional highway use ( has nice 3:21 rear )
I mean I don’t abuse this thing at all
Best if you don’t let it idle, as soon as you get oil pressure it’s best to keep it in the 2000 rpm range as that is where you get the best lubrication to your bearings. It’s also best to avoid short drives as you need to heat the oil to rid it of moisture and water. Moisture kills oil and wrecks engines. Heat cycling kills oil. I have had my oil tested to tell when to change it acouple of times to give me the longevity of it’s life. This was in my daily driver, 40 minutes to work each way. Testing lab results indicated oil change intervals with Amsoil was 15-18k the way I was driving.
