Hit 1,000 hours on my oil sample log and the one flagged engine still bugs me
I keep a little notebook in the truck for every oil sample I pull, and it hit 1,000 entries back in March. The one that stuck with me was number 847, a 2016 Freightliner out of Amarillo showing iron at 140 ppm, so I flagged it and told the driver we should drop the pan. He traded it in two weeks later without letting me look, and I still wonder if that motor let go on the next owner. For those of you pulling samples regular, what iron number makes you stop everything and crawl under the truck?
