My car arrived on Sat. and it had between 1/2 and 3/4 tank of gas already in it (I was surprised it was that full). It had 5 miles on it then. My salesman and I both went to fill it up together and he put in 93 octane gas, so I am good there. My question is did GM put 93 octane gas from the factory or do they put in the cheap 87 octane there?

I will do the fuse pull later on (225 miles on it now) just to be sure but I wonder what grade of gas the GM factory folks put in it there?
