Geez Patrick, I thought your flavor was Chalupa!
Seriously though, what Patrick said is true with fuel and
oil. Just keep an eye on it and check the pipes now and again. I have run a tank of 110 octane in my car before (actually even higher) and the smell is like night/day.
Also, you say "your first
oil change". I am assuming that someone else did it in the past few thousand miles?
What did your
oil look like when you drained it?
