not true, I change my oil every 5000 miles and send a sample into Blackstone each time and they all come back fine. My last oil change I did at 229,000 and added Archoil to it and within a couple of weeks my truck was running extremely rough and then wouldn't start. When filter was removed the same exact thing was found. Also when oil was drained it looked like a a light brown clumps of thick soup. Those saying it's a poorly maintained truck don't have a clue

sample was sent into Blackstone and waiting on call back from Archoil. The more the subject is researched the more, the more people are having issues

20-25 miles each day to work and also used for traveling. I have owned /used the truck the same way since 2008 and never had any issues. As I said I have all the oil samples from Blackstone ( most recent was mid December with 229,500 on truck and 4700 on oil truck now has 230,300) the only thing done differently was the Archoil 9100 added approximately a week of so later

Did you perhaps forget to shake the archoil before filling it into the engine?
Perhaps additives had settled in the Archoil can?

it would appear that alot of people have used Archoil 9100 with no issues and love it. But there are those who have used it and had no results or catastrophic problems with it. But the ones on here making blanket statements about poor maintenance, lack of maintenance and/or using a oil stop leak in their oil are uneducated on how some of us maintain our trucks. I'll wait to hear back from Blackstone and another independent oil analyst to see their findings.

Archoil AR9100 contains the following ingredients:
Playing devils advocate here perhaps Archoil, like every other company now a days has quality control issues and some batches are way off from other batches and the bad batches are causing this clumping of oil somehow? Now I doubt this is the case, but MAYBE an excess of the nanoborate causes all the baked on micro soot inside the engine to be stripped off and then the excess soot particles combine with the paraffin oil and chemicals in the engine oil and get "baked" together from the intense heat causing all that goop/sludge?
Again, I doubt that's what's happening here, but then again I never imagined the whole of North America would be run by clowns and at the same time so I guess anything is possible lol
- Potassium tetraborate: A nanoborate friction modifier that reduces friction between surfaces
- Fatty acid ester: A chemical component of AR9100
- Methyl oleate: A chemical component of AR9100
- Tetra ester: A chemical component of AR9100
- Paraffin: A chemical component of AR910

I have a bottle of 9100 on the shelf that I have had for a long time, quit using it long ago, I'll look and see if it has separated.
Do the clumps dissolve in anything, lacquer thinner, diesel, etc?

Again I doubt the ar9100 is the cause of the clumping as I've ran double doses for 8000km intervals with 0w40 T6 and the oil has come out as thin as water and filter always looked new and clean, but anything is possible and I like to keep an open mind in most cases except for people who see ghosts or think the world is flat lol
