2007 Ram 1500
3.7l V6 (iron block, aluminum heads)
135,000 miles at time of sample, 5000mi interval

Did the analysis to see if I can extend the interval. Going to send a sample off at 7k to see where I am and if all is good try and get to 10k.

I did see that my silicon and sodium are higher than average. Wondering if it is time for a new air filter?
Blackstone said no sign of anti-freeze or water so could the sodium be from the additive package?

A second good looking UOA today on Valvoline synthetic. I see no reason to be concerned with going to a 7-7.5k OCI and perhaps beyond. Additional analysis will show of 10k is possible. I suspect it will be.

The sodium is part of the add pack so, nothing to worry about. Silicon is a little high so, you probably should replace the air filter. Nice report!!

5000 miles and TBN = 2.9 with 15 ppm Iron and still in grade with KV100 = 8.57 cSt

Good report and still lots of life left in the oil.

*update*
So in general I think the higher copper, and higher metals all around, is from how I drew the sample I sent off (did not drain and replace). I used some small diameter air hose to siphon out of the dipstick tube to get the sample. Since it was a cold sample and the tube was probably hitting the bottom of the pan...I think I got all the dregs at the bottom that they tell you not to send in (supposed to pull the sample from the middle of the oil drain is the way I understand it). Won't know for sure until the 10k sample though.

Silicon is still high despite the new air filter. I inspected all of the tubing and such and there are no leaks. I think it is just that I really am driving through a lot of fine dirt dust everyday. Gravel roads near my house, and never ending road construction on the highway. I'm not super worried at this point.

Thanks for the update....2500 miles longer and the TBN barely budged - very nice. If gravel roads are involved, you're silicon looks fine - 18ppm in 7.5k is acceptable IMO. Valvoline delivers again.

So last time I thought the high copper was just me drawing from the bottom of the pan for the sample...now I am very confused confused

Oil is the same fill as the 7.5k sample

They way I understand it copper is only an issue if there is other wear metals in unusually high amounts. Other wear metals are at normal ranges for the mileage on the oil. I also read that if the oil gets acidic then it can pull copper from the oil cooler, but wouldn't the TBN have to be low for that to happen?
Actually what is up with the TBN not changing? Is that normal?

To be honest I'm not sure what to make of the results. I'm going to do another sample at 7-7.5k and see what that turns up but would like to hear any thoughts.

Your iron wear is fine, your TBN is steady - it depletes slower as it gets lower (so I've heard). But what catches my eye is that the KV100 viscosity is increasing and the flash point is decreasing.

It started off as a 20 grade oil, but with KV100 = 9.9 cSt it's now a 30 grade oil. Is this oxidative thickening ?

What is oxidative thickening? Well really what does that mean in application (I gather that it is the hydrocarbons oxidizing or somesuch)?

If I remember the owners manual correctly 5w30 and 5w20 are both recommended for the engine. I go 0w20 due to availability (it wasn't commonly available when this engine was produced but others have had good results using it in the 3.7l).
