50/50 city highway. Truck is a work truck and gets a good workout around Houston.
I have no idea about the silicon, but we had a really dusty Spring and I have a CAI. Lead is not high, so I'm not worried at all.
I used a Mobil 1 filter. Refilled with the same oil. Truck runs like a top, never had to add any make up oil.
Prior runs were Mobil 1 5w30 EP and TSUV.
