no idea. I've never needed one. >..>;; NY is insulated by the atlantic ocean, so it doesn't get *that* cold here.

yeah youre lucky, I wish I was in Newark, f### these mountains

um, anti-freeze ?

Only works to a specific temperature. And there's other issues besides just engine coolant, like fuel and lubricants being too cold to function

yeah at this temperature Oil becomes like mollasses, cant get everywhere it needs to be in the engine. Is there a like winterized oil, like 10W-30 is for one temperature range right? isnt there one for lower temps?

I only use 10w-30 in the summer. It's not rated for cold... really. in the winter, I want my car to have 5w-30. REally, i try to get 5w-30 in it all th etime, but some times it's out of my control (like when the asshats at walmart do it for me)

yeah but its cheap, my dealer is giving me a free change with the car, so ill see if theyll put in 5w-30

5w-30 is designed for use in sub-zero and all temperatures that are cold. I've seen trasnmission fluid physically freeze before. (well, not seen, but seen the effects of)... Antifreeze in your radiator is a must, and make sure your carborateur hasnt collected any ice or anything from condensation...

Assuming you're still using carburated car... I'm fairly certain that every new car is Fuel injected in some way.

My Seat Cordoba had a carb and a (single) fuel injector. But that wasn't a new car. On a similar note, probably worth checking the air box & inlet tract.

Yes, but then you can check to see if the fuel lines are frozen.
