That might explain the higher number for iron in that amount of miles. Short trips and such are harder on engine and oil. I wouldn't worry but send in another sample after another 5000 or so miles.

 

Yeah, I rarely go more than 15-20 miles in one day... It's only 3 miles to work, but I usually get it to operating temp by that time. (in the summer at least)

It's an 04.5 that I bought in Aug of 04, and it is just about to roll over 70k, if that tells you anything. I do change the oil about every 3k, though. Overkill, I know, but...

That, and I drive around at 575-600 hp on any given day... that can't be good for it...

 

I know the need for speed. Or at least power. I haven't driven around at those power levels in awhile. Usually I'm around 400 or so daily driving. Higher HP levels are going to put a little more wear on the engine obviously but I don't think you've hurt anything.
Quick story about Blackstone and my truck. I received a report where my copper skyrocketed to 60ppm. So they were talking about turbo problems or maybe oil cooler issues. My iron was also elevated at 45. Next report after 4000 miles on new oil and copper dropped to 37 and iron to 27. Next 6000 miles and copper was 24 and iron also 24. Not happy but getting better.
So I did research. And guess what. Prior to the first bad report I did my ARP headstuds. And I bought a pint of ARP lube because I was told the amount given with the studs wasn't enough. So I slathered that stuff on. And guess what is an ingredient in the lube??? COPPER... and other metals which thru my samples off.
Lesson learned. And it made total sense to me after that. I think I posted a thread on it here and on BITOG.
Anyhow my averages are near the universals now and aluminum and chromium are actually less. My Cummins is doing fine... (knocking on wood)

 

My iron was high on my '07 with the same short trip scenerio as you. I changed it and went on a 1600 mile trip and lo and behold the next analysis came back perfect. These truck deserve to be driven hard.

 

Have y'all tried Oil Analyzers? I just got my first report from them. They seem a little slow on the email reports IMO.

Sorry, didn't mean to Hijack.

 

No, it's about information here... do you have a copy of the report?

 

Yeah, it's for my wife's Expedition though. I installed a dual bypass filtration system on it. Trying to figure out how to download it from my new email system.

 

Here's the analysis. Dual filtration system installed at 3K and sampled at 26K. Added 2 qts during the 23K. Sump is 9 qts with duals on it.

Here's the article I wrote for the installation.

Linkys no worky. My sump held 12 quarts - stock.

 

I'm glad someone esle has noticed this.
I have seen several of their reports that make little sense. very pleasant and detailed...but wrong and overly expensive!
They still claim any TBN above 0 is OK?? Nobody does that. TBN should be flagged at half life!
Your TBN of 5.8, on "so few miles" would bother me.
And as stated above, Iron level is normal for about 10,000 miles, based on other CTD reports I've seen.

That's weird, they work for me. I'll reboot to clear memory and try again.

 

Madhat said it had spent some time sitting unused during that period, which could explain the TBN drop.

Blackstone is a company made up of people, not unlike any other. Their analysis is not "in-depth." They (as a group) have a grab bag of commonly used terms and references to describe typical results they see. It would not be unreasonable to assume one of the lazy or incompetent ones grabs the wrong thing out of the bag from time to time. I would not base any UOA conclusions on any single report. I rely soley on the numbers and trending over time for my own analysis.

 

What makes you say that?
I know of no chemical or physical reason why TBN additives would deplete sitting on a shelf or in an unused engine.

How do you get to operating temp in 3 miles? Even in the summer it takes me 6-9 miles.


The TBN is quite low for 2400 miles. (After 20K miles I was still at 6.7) Is the Rotella the syn or dino? (Even the dino starts at 11.5).

 

Short trips are VERY hard on TBN in gassers, and I would assume diesels as well. When the engine is cold you get more combustion blow-by, thus eating the TBN faster.
