I know a block heater, or oil pan heater, is nice to have, but don't get one thinking it's needed.
The JK will start just fine at -30°F.
Cold starts, while not ideal, don't seem to be a problem with today's engines and oils.
In fact, some people who have them on their JKs have posted about check engine lights coming on because the computer thinks the water temp sensor is reading incorrectly. (It compares water temp, ambient are temp, time since shutdown, etc.)

ok i understand that it is not required. i have had my jeep for about four years in NY and it does get cold and wintery there. but recently going to Maine its going to be a little worse i think and i know the jeep did great in NY with the temps and elements but it did take a while for it to get up and warm running. i feel that having these things warm close to operating parameters the easier the jeep has to work to maintain itself. and for some reason my jeep appears to be starting rougher now then in NY and I am always on top of my maintenance and the plugs and wires and battery are all new and working properly its just definitely colder out side and my vehicle does sit for a few days every couple of days due to my work rotation being in the Coast Guard. well i greatly appreciate everyone's input with this it has been a great help locating my non existent block heater and how great they work in the harsh elements.

Glad I noticed this thread. Went out and checked my 10 JKUS. Found the cord for the heater wrapped up by the battery. Going to run the wire tomorrow and zip tie it down.

If my JK stopped starting well at -15°F, I'd be looking into why. Even my VW TDI diesel starts well at those low temperatures.

just because it starts does not mean it would be easier on the engine and starter if a block heater was used. We have gone over 30 days straight without being above 0F and people who parked inside or had block heaters probably were thankful. I know I was. minus 7 here this morning and glad I am plugged in. Necessary nope but it makes me feel better and I can tell my rigs turn over easier.
