Stop in for a cup of coffee

So how concerned should I be?

Dealer screwed up the oil change on the Hemi today. Ever since I’ve had it, I’ve paid them to do full synthetic oil. Well they put a synthetic blend in today :BangHead: :BangHead:

Now they’ve credited me my money back and giving me my next oil change free(they’re 3 hours round trip from home or I’d take it back already). Their service manager has been really helpful correcting it. But he says nothing to worry about. It was the correct grade, just not full synthetic. To ease my mind, he notated the account and will be sending my oil off for an analysis after the next change, on their dime.

Just strikes me odd and I’m afraid he’s over compensating for some reason.

Is there any concerns with going from full synthetic to a blend in a modern engine designed for either or?
