This is from my 2011 Taurus' fantastic 3.5L V6 (naturally aspirated). This sample was taken last october (2014) after a 51 week run. The miles accumulated were mostly rural back roads (many of them dirt) with some state roads mixed in. While we do climb a lot of 12-15% grades, that's more of a transmission concern, the engine rarely goes over 2250 rpm. Mostly runs 1,000 to 1,500 rpm. More than anything it's driven 6-7 miles at a time, some very short trips and once per week it gets out for a 44 mile round trip. Odometer at sample was 39,464.
You will see that insolubles were way high.
I have not taken the time to dissect the filter yet. The truth is that I just recently sent the sample in after five months sitting (ok, actually buried) in my garage. I shook it up several times over a couple days before mailing it. I don't know if sitting so long caused an issue with the insols or not. Filter was Fram XG10575.
Blackstone notes: Dusty: Wear metals look great again, staying low and steady compared to previous samples. The only mark was for insolubles, showing that your oil filter was used up. For that reason, we would not go not go much more than 6,000 or 7,000 miles on next oil. TBN was 3.0 and TAN read at 4.1. Other than the insolubles things look great.
