Every time I started the engine, the exhaust pipe smell of gasoline...

[grape]

it's a brand new car... I wonder if it's normal. and a lot steams coming out
of the pipe.

Since it's brand new, why not ask the dealer? If your dealer doesn't
give you a good answer, you could take it to either another dealer or
an independant shop that specialized in Suburu and ask their opinion.

You didn't mention your gas milage. If you're leaking raw gas out the
tail pipe (not likely, if the catalytic converter is working at all),
I suspect your MPG will be suffering.

Normal.
ECU richens mixture for cold starting so
you will smell unburnt gas immediately on start-up...
a little goes a long way.......................
and the 'steam' is water vapour, a product
of combustion always there but more noticeable
in cold weather and will go when the engine/
exhaust reaches operating temperature.
Mine does it...don't lose sleep.

Normal...if starting from cold and I've never owned a car
that didn't do the same.
ECU richens mixture for cold starting so you get a little
unburnt fuel at first blown out the exhaust...and the 'steam'
is water vapour, a combustion product...again normal and always
there but noticeable in cold weather. It disappears when
correct operating temperature is reached.
If in doubt consult dealer.

Weird...first post fell off my screen
and not in sent items.
Please pardon duplication.

are u sure?

yes, it goes away after 45 secs, and then fainted... the steam also reduced,
and after driving a bit, I smell the exhaust pipe, and nothing can be
smelled.

so u sure it's normal? I just don't want to be look dork/stupid if I give it
back to dealer.

The car has 1500km on it so far. and the L/100km is around 9.2(combined
highway and local, measured between two gas tank fillup)

I sure willing to give back to the dealer, but first I have to be sure about
things

 

[grape]

btw, it's very rich smell, you can smell it if you stand at the end of your
car.

I agree - cold engines do what they have to in order to start and warm up,
and that involves richness. As long as it's okay after warmup you are good
to go.

I ran through the chemistry of burning gasoline once and it's true: burning
a gallon of gasoline produces almost exactly a gallon of water as steam! It
seems wrong because a gallon of gasoline only weighs about 6 lbs while a
gallon of water weighs a smidge over 8 lbs, but that's what adding oxygen
does to it.

He shouldn't _ever_ be able to smell raw
<unburned> fuel, if the cats are present
and working.

Hi,

Don't know how sensitive his nose is, but cats DO take a minute or so to
heat up, and I've smelled "very rich" exhaust from several of my cars at
startup when they're "cold" (I'm thinking below 40 deg F which is barely
"cool" to some of the folks here--don't recall if the OP said how cold
it is where he's located.) Considering I can't smell for beans, it's
likely they could have smelled like raw fuel to someone with a good
nose.
