Maybe, but I think it could've been the gas.

Agree. I asked my sales rep what kind of gas he put in the tank (I got Free full tank) and he assured me it was premium. I told him I have a device that I can use to check if it's premium or not (I was just bs'ing around) and if it's not premium, I'm bringing the Z back! His reply, " I swear, I put 93 premium!"... I was just joking anyway...
To the OP, you'll be fine. Just wait till the tank is half or 1/4, then fill it up with 93.
