Apparently my motor doesn't like Amsoil run this long according to Blackstone. This was a 10 month run of this oil and I did not put as many miles on it this year as I did in the past. Total makeup oil was 8 quarts. I change the frantz every 2k and add a quart. A donaldson fitler was used during the whole oci and a eao air filter. First column is current oci, second is the same oil at 9972 miles, and the third column is rotella dino at 10,179 miles. Truck has 61509 on it at the time of this current sample. Let me know what you guys think, I like the AME and would like to keep running it up to a one year oci up to 25k. Also three qts of makeup oil was ACD 10w30.

Don't flame me for not getting a TBN done. I just figured with as much makeup oil as I had, there should be no reason for a low tbn.
Blackstone said, you are into the bearings with this 16233 mile oil run. Note the 10-fold increase in copper. We found no harmful contamination in the oil which would cause this poor wearing bottom end, so the conclusion is, the oil was run too long. They continue to say that I should try a dino oil like rotella or delo because they hold up under long use and have a high TBN. Also I have been towing a lot more, nothing extreme though.
