Only MOPAR brand or Zerex G-05 coolant for a Jeep, built after about 2000 or 2001.

Maybe it is now time to drain and flush your system, since you added Prestone. If you only added a little, it probably won't matter.
Flush procedures for a TJ here. JK will be similar.

I hope there is water in yours! Proper antifreeze/water mix is important, and is usually a 50/50 mix of antifreeze and distilled water = approximately 34 degrees below zero protection, plus summer boil-over protection.
You can actually go up to 70% antifreeze & 30% water, for maximum freeze protection, but not more.
If you go over 70% antifreeze, your freeze protection actually gets worse! 100% antifreeze has poor freeze protection.
The proper antifreeze for your Jeep is ONLY Mopar brand, or Zerex G-05 antifreeze, which is a HOAT type coolant.

Proper coolant/water ratios are on the back of the jug. DO NOT use any "universal type" antifreeze.
Use caution when purchasing antifreeze. Some jugs are pre-mixed with 50/50 antifreeze and water. DO NOT add water to those. Other jugs are 100% antifreeze - then mix accordingly.

looks like i'm going to flush and replace with mopar...
seems odd that they would tell me to use straight fluid...
maybe it is pre-mixed...i'll have to check it out...
many thanks for the info...

if you added a quart (liter) or less you have no worries.

checked my GM product...yep...needs to be diluted half and half...
also checked my motorcycle coolant...i have a v-max...
it's already diluted...so you just add it and no water...
that's how i got confused i reckon...
