Top tier gas has nothing to do with fuel solution nor will it prevent IVD. Choice of oil and the PCV have an impact.

I'm not sure I buy that. You can if you want. That's up to you.
Your proposal that choice of oil is relevant while ignoring that significant gasoline contamination occurs frequently but top tier gas has "nothing to do with fuel solution" seems nonsensical to me. And NOTHING can prevent intake valve deposits. They can be minimized, but not prevented.
