Oil Analysis Thread - 3.0 EcoDiesel

[Motoristx]

You’re right, it just shows low mileage, not dashes. One of my other cars did dashes. Mine was at low mileage this morning and I fit 15 gallons in it…

I’m sure it’s not good for it, but oh well. I run till low mileage, and I run 10k miles per oil change.

Your fueling behavior displeases the internet. There may be consequences…

I didn't see an oil analysis thread for the 3.0 Diesel. I recently had a oil change and had them pull a sample (about 9000 miles). I thought if there wasn't a thread already up, I'd start one. Here's what I have so far but needing to get additional information for filter brands and oil brands etc.

Looks like they "flagged" copper and potassium.

9K miles is way too many. The potassium is really odd.

Thanks for sharing your data.

How many miles on the Jeep, and how many miles between oil changes?

Around 83,000 and change it around 7k. It's on the sheet.

I do run fuel treatment in since my first HP fuel pump went out. Still run till the light comes on. 135k miles.
