Because there is gas in it.
If you have a motor other than the car such as a lawn mower in the trunk it smells. Also if you just got gas it smells.
More than likely because its leaking. If the gas smell is stronger in the trunk then that normally indicates that there is a leak in a fuel line around or on top of the tank...usually it is on top of the tank because dirt/salt ect can build up on the tank and the lines corrode... If the smell is stronger inside the car then it could indicate a leak in the fuel line from the engine compartment to the center point of the car... None the less if you are smelling gas then there is a leak somewhere in the system and you should have it checked before it catches fire and burns up...
You have a gas leak.
because your engine is going to break down or when you start the car if the whether is cold, it makes it smell like gas
Varnish, or in other words it does not smell like gas, it smells almost burnt
probably not you have a gas line leak
because oil is refined into gas
It is possible that a car can smell like gas when the heater is turned on for a few reasons. One possible reason that this happens could be a leak in the line.
it should NOT.......you have a GAS leak fix it ...unless you overfill gas tank then maybe that's smell temp.
If a car begins to smell like rotten eggs and then starts acting like it has bad gas, it may have been filled with the wrong type of fuel. This smell is common when diesel fuel is burned.
my car smells like i have a petrol leak when i turn it on but have no leak underneath the car
Check your fuel cap or gas tank for leaks, or maybe the gas lines.
