How many miles do you have on your 6.7? This sample looks excellent either way. pretty sure that Fram, Oreilly's, kirkland, there is a few more cheap oils that are formulated the same it seems. I've heard they are blended by the same manufacturer.Lot's of towing this round. Changed a little earlier than I wanted but I was doing some other maint and decided to do it

That's great! Your avg miles are 12,622 with an avg wear rate on iron of 28 over these 5 sample's.Little over 151,000 right now.
Not familiar with the oil? It's Costco house brand, rumored to be the same or similar as supertech. I think the last 5 uoa from this truck are with it.5 samples averaging a tad above 2ppm/1k miles of Fe is very good for a towing application. Very good indeed.
The other metals are low enough to just be ignored.
All contaminnants are low.
Soldier on!
I'm not familar with this product, but it seems to be doing just fine.
Assuming same regimen, what is the farthest you would take this oil?Lot's of towing this round. Changed a little earlier than I wanted but I was doing some other maint and decided to do it
I've been wanting to go 15k for awhile but the timing of when I do my oil changes has not worked out.Assuming same regimen, what is the farthest you would take this oil?
I recognize the brand name, certainly.Not familiar with the oil? It's Costco house brand, rumored to be the same or similar as supertech. I think the last 5 uoa from this truck are with it.
Currently blended by Warren. It's a regular dino I am pretty sure. I would be surprised if it's much different than supertech.I recognize the brand name, certainly.
I was perhaps less than descriptive in my question ...
I'm not familiar with the composition and make up. Is this a conventional, semi or full syn? Do you have a VOA for the oil?
The results are admirable. Just was curious about the lube itself.
No mention of being synthetic or synthetic blend as far as I can tell from Costco website and product images Dave.I recognize the brand name, certainly.

No I can't. It's always been like that, sometimes it comes back high, sometimes zero. Could be related to how close to a regen it was sampled but I don't track that.Can you explain the change in fuel dilution from sample 12 to 13 to 14? Any reason you would know of?
