Wanna Be-
Have you considered one of those HIGH TEC evergreen trees hanging from the rear view mirror?!!?
Seriously, what you're smelling are some of the organic components of fuel that are chemically sticky. Once airborne, they latch onto many components or your interior. They will "fall off" over time, so rather than competing them off with a different smelly compound, consider parking with the windows down for a while. As the weather in your area is still wet, you might use your garage space to house the car, windows open for a while. This will help "air out" the interior and drop the gas smell.
Interestingly, our noses are really sensistive to certain compounds and we smell them at very low levels, even below their toxicity. For example, the "smell" of natural gas is added so we can detect a leak, but the smelly componet is a sulfur-compound at exceedingly low levels. The smell of fuel in your car is annoying, but not likely to be toxic.
Good luck!
