It is used every morning. Do I have a valid concern? It's under the StarMark warranty and as long as that remains in effect I will have my indy or the dealer do the change. What do you guys think?

D, I'll play devil's advocate since the car is still covered by warranty. They may attempt to deny a warranty claim since the oil you mention does NOT meet the mfr's spec for lube oil.
