ok...after doing a bunch of reading....I've settled
on my plan of attack....

I'm gonna go ahead and use the Amsoil 5w30 that
I just bought, run it for the 7500 miles, then I will
change it out and start using Royal Purple 5w30.

Mobil1 being a Group III synthetic, Amsoil being a
Group IV synthetic, and Royal Purple being a
Group V synthetic. Royal Purple is touted as
performing "..very well.." as long as its changed at
the recommended 7500 mile interval, and, its
cheaper per quart than the Amsoil.

So rather than pay the higher price and run the
extended service Amsoil, that I would be changing
at the 7500 mile limit anyway to maintain the
warranty, and, also maybe running a risk of
shortening my converter life(?), I will use the Royal
Purple instead....give me the best of both worlds.

And keep in mind, this is IMHO.....this is NOT a
recommendation, it's simply what I have chosen to
do...(not wanting to start a conflict here...)
