I switched over to Mobil 1 around 60K, now I have almost 120K on her and she is just broken in.

I use NAPA Gold filters (oil and air), do not use a drop of oil for the 10K change intervals. Around 80K I sent the oil in for analysis to Blackstone and it came back saying the oil is still good for another 3K and it showed wear like an engine with half the miles I have.
I purchased the truck in 2004 with 7K miles on it, it was a great find at $22K.
