Smell of gasoline

[Francis]

When I start the car in my garage with the garage door open, I always smell of strong gasoline when I am outside the car. I have done the 30k, 60k and 90k maintenance at the dealer. The car is 115k miles now. My mpg is about the same 21. I don’t see any smoke from the exhaust pipe. It happens since half year ago. What do you think the problem is? I need smoke check pretty soon. Do you think I will pass?
