I am looking to make a day of changing all the fluids in the jeep (coolant, front and rear diff oil, Engine oil, trans Fluid, etc.) What are you all using? I am not sure when or if any of the front or rear diff or trans fluid and coolant have ever been changed in my jeep, it has low miles at 40k and rarely gets driven but I just wanted a good weekend day project.

I am currently using the Mobil 1 for oil changes, this is what I have been running since I owned the jeep at 36K or for about a year.

I am interested to know what is being used and what effects have been noticed since the switch.

Thanks,
Kevin

I listed ALL the fluids like you asked for, no one else did. If you wanted a fluid BRAND debate that is really worthless as it'll go on forever.........

I must apologize, I did list one fake fluid just for a little fun.... hope you didn't get upset.

you just seemed to give a mocking answer i was just looking for ideas on what to use, opinions on fluids are like that of everything, they are opinions and no one will ever completly agree. I wasnt looking start an argument, just more for guidence on what is good to use, i heard as far as replacing trans and transfercase fluids as well as diff fluids to use the factory suggested stuff...who knows ill just go with my original plan, royal purple in the diffs and mobil in the engine factory spec for trans and transfer case...etc.

BTW Changed my blinker fluid. Now they work like a champ,but my muffler bearing is squeaking.
