Oil sample take a look and comment please

Looks ok. Sodium is up a little. Watch for coolant loss.
I guess you're doing extended changes.
Personally, I don't have much faith in Speedco oil analysis. I'd rather send it to a lab.
The highlighted viscosity number is only one point above spec, and two points higher than two samples ago. Doesn't seem like much.
I went the extended drain route with my last truck with a Cat, with a big bypass filter.
Now I have the Amsoil bypass filter but I'm still going to change at 15,000.
The rebuild only has 45,000 on it. The samples are coming back excellent. The lab is recommending extending drains. I might go 20 but that's about it.
