I'm not worried about the silicone but the flagging of titanium seems a bit odd. Isn't that an oil additive? I think I'll stay with 3000mi OCIs vs the factory recommended 6000. I would hate to see the fuel dilution at 6000mi. Oil is cheap in the grand scheme of things. Once my case of Schaeffer 0W-20 is exhausted, I'll be switching to Pennzoil Ultra Platinum 0W-20.
