First I gotta say, I doubt it was fuel that spit out. If you're referring to a fluid comming out of the exhuast, it should be water. That is the byproduct of the catalyst. This is normal, I believe the cat convertor, converts carbon dioxide into water
It is normal don't worry about that. The black smoke on the other hand... Check your oil level. Is it low? Maybe you're burning oil? Which could mean bad rings, worn out valves, or a couple of other things. Watch your oil for a few days. Does your car still smoke or did it eventually go away? How many miles, etc. on the car?? Did you maybe have a batch of bad gas? If the car idles rough you might want to check your ignition coils. Good luck.

Maybe I'm wrong. Maybe it's just water that's white.

Yeah, I'm not really certain either IanS. I think you are right though. I don't see any symptoms listed in my Haynes manual so I can't help you out any more other than saying that there should be no smoke comming out of your exhuast. I would guess you're either burning oil or not burning all of the gas. Hope something in here helps.

First thing. Check the oil. Is there anything abnormal on the oil on the dipstick? Milky? Frothy? Too much oil?
Now pull your spark plugs one at a time and check their condition. See if any are excessively black with soft carbon or ... gulp... covered in oil/goop.
Was is running roughly? What have you done recently? Oil changes, tuneups, etc????

black smoke is rick mixture, blue smoke is burning oil and white smoke is burning coolant. make sure its black smoke and not blue. sometimes people can confuse the 2.

Spend the extra cash on some Texaco or Chevron or Exxon 92, or even 93 if you have it in your area.

So you filled it up with another brand and the smoke went away?
