Warranty says you have to show evidence of using an API certified 0w-20. Using the Schaeffer oil thickener of about a cup would mean you could not tell Honda about that, and Honda wouldn't know. Using an Xw-X0 of anything other than 0w-20 means they won't honor the engine warranty if they suspect you used the non-recommended oil. You could just take the chance there would never be an engine warranty claim over the next 6 years. Amsoil SS and Redline are not API, so they are out.
I appreciate the suggestion. If it was mine, or, if I even lived near her, it might be an option. But, as it is, with her living 7 hrs away, I'm not in a position to take responsibility for maintenance. The best I can do here is to suggest a good oil and suggest that she not go over 5K on OCI. And it's my opinion that a 30W oil will serve this engine well in consideration of the known fuel contamination problem with these engines.
I'll also suggest that she get a UOA - not on the FF, but on the next oil change.
