So how worried should I be by these fumes.

I just bought a 2007 Hyundai Elantra. I'm having some issues with fumes.
I bought this car in August. It has an issue where during start and sometimes during usage it will have engine fumes come out of the air conditing unit during startup and occasionally during use. I did have a check engine light after I accidentally put Supreme in. I resolved that used fuel system cleaner in the oil fill section and an oil change . I checked yesterday to see if there were any leaks by running it for 5 minutes on top of my concrete drive way. I did get some water leakage but no fuel leakage and it didn't appear to be coolant either. It does have 112,000 miles so I think it might be blowby but I'm not sure . Whats the worst case and the best case scenario. I really don't know all that much about cars but I'm troubleshooting the same way I do for everything.
