only 2 reasons if here was no smell before changing filter. did you spill gasoline? the smell will go away. is the filter leaking?
Even when your vents are closed, air still is being pulled into the car. The musty smell means you inside cabin air filter needs to be changed. You can gain access to the filter through your glove box.
Smell may be (heated) mouse dropping and urine. We found a mouse nest in the (and partially made from the) air filter. Open the air filter and check, mouse was still hiding down the air hose. This search was done in an attempt to find that sour smell.

Remove the old filter. Replace it with a new filter. Before installing the new filter wipe the mounting surface clean and apply a coat of oil to the new oil filter's gasket. Spin on the filter and tighten it 3/4 turn after it makes contact with the mounting surface. No, more and no less. If you still see oil leaking from the filter then look above the filter for the leak. Possibly valve cover is leaking.
no it will not smell bad it will smell good, but you will still be sweaty deoderant just covers the smell anti-perspirant stops you from sweating
There are several reasons your filter may leak. It might be the wrong filter. Did you oil the gasket before installing it. Did you over torque it (more than 1 turn after contact). Did you make sure the old oil gasket wasn't still on the engine block before installing the new filter. Could be a defective filter(bad gasket). In any case, better replace it to be safe, filters aren't supposed to leak. Better spend 3 to 4 bucks now than 3000 bucks later on a rebuilt engine.
This is the normal gasoline used for modern cars, only some older ones still need leaded gasoline.
no
yes
The smell is not dangerous - however, if there is still a smell, there could still be urine, which could cause diseases and infections if you come in contact with it.
You can still do everything you normally would. You just wouldn't be able to smell.
Physical change, because no matter what the colour is, its still gasoline.
