Previous oil changes were:
Castrol GTX 5W-20 and Mobil-1 oil filter every 3,000 miles.
26290 Mobil-1 0W-20 SS changed out with Mobil-1 0W-20 SS and Mobil-1 oil filter. Winter short trips and improperly seated air filter.
29350 Mobil-1 0W-20 SS changed out with Mobil-1 0W-20 SS and Wil oil filter. Air filter changed during this run; Napa Gold.
32456 Mobil-1 5W-30 SS changed out with Mobil-1 5W-30 SS and Motorcraft FL-820S oil filter. NOTE: Do to an error in the manual, on every past oil change 5 quarts of oil had been added...it turns out that the 1st printing of the manual is wrong, and that the new priting details 6 quarts of oil to be used. Therefore, these first 3 analysis' reflect 5 quarts of oil being used, and subsequent analsis' will reflect 6 quarts of oil being used. I'll do 2 more Mobil-1 0W-20 analsis to get a baseline going with 6 quarts vs. 5 quarts, and then I'm going to start switching up the oil.

Blackstone Comments: Nice improvement in iron. It and all the wear metals are now reading at or below average for this type of engine and this is a very good indication of normal wearing parts. The oil was normal in viscosity for a 0W/20 and we found no fuel dilution or anti-freeze. The TBN was okay at 4.5. This is a little lower than the 4.9 we found last time, but still well above our problem level of 1.0. Insolubles were low at 0.4% showing good oil filtration. At 32,456 total miles, we think this engine is doing well. Suggest going to 5,000 miles on the next oil.
