Blackstone Comments: You have been keeping your oil use intervals steady around 5,000 miles and your engine is rewarding you with steady wear trends. All wear continues to read well within the average range for this type of engine after a little longer than average oil run, so we don't think any problems are developing. The oil was normal in viscosity and free of any harmful contaminants. The TBN was still strong at 3.5, so the oil has plenty of active additive left. You were at 5.8 last time. Feel free to run the next oil longer. 7,000 miles should be not be a problem.
My comments: This was the first run of my truck doing very short trips twice a day, like 2 miles. Also, been in a careless mood lately, so there were many many days I drove it fairly hard to get to the train station on time, so, truck wasn't even warmed up and I was beating on it. Still did a fair amount of highway, however, at least half of this mileage was very short trip driving around town. Take this into account when comparing this UOA with my past ones which say mostly highway driving. Another thing to note is that while the 5 qt. jug I used for this UOA said ILSAC GF-3 and API SL, you can see by the additive levels when comparing to the below VOA I did on the Mobil-1 5W-30 ILSAC GF-4 API SM I put in to replace this UOA, that this UOA is most probably also the ILSAC GF-4 API SM Mobil-1 EP.
Very interesting how short trip driving, driving the truck hard while not warmed up (granted, the temperatures were still warm/mild), and the decreased additive levels all combined to produce a UOA that really isn't all that different than the past UOA's I had which were mostly all highway and had higher additive levels.

P.S. I know I can go longer than 5,000 miles on Mobil-1, however I cannot do so and remain under warranty. In less than 20,000 miles, we'll start seeing how Mobil-1 and other synthetics can handle longer intervals in this engine.
