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.


The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money

No only thing thatís been done is head studs, itís not loosing coolant I think itís just left over from when I used archoil in the previous oil change, Iím waiting on oil to come in so I can change it again and see if the potassium goes down. Iíve 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

Why does the oil report state Amsoil 5W30 was the viscosity?


Just say NO to thin oils and M1!

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
