Just giving a view of my oil analysis would love some input also potassium is high because I used archoil prior to this oil change

1) welcome to the site
2) wear data looks very good
3) do you have any degas bottle spillage? Curious if this could be an onset of cooler concerns
4) has the vehicle received any updates to address oil cooler issues?



PS - please follow our convention of thread titles; helps with searches in the future. I've updated it for you.
 
No only thing that’s been done is head studs, it’s not loosing coolant I think it’s just left over from when I used archoil in the previous oil change, I’m waiting on oil to come in so I can change it again and see if the potassium goes down. I’ve made it to 12k miles on this oci and with it being my first use of amsoil I think my next run I can get an easy 15k. Also thanks for fixing it lol

And lube time on report says 10k (conflicting with the title)??

Wear numbers and fuel dilution look good.

This was the max duty 5w40, I switched over to the diesel and marine 15w40 since it's more for trucks pre dpf
