so what is everyone using? I just read the wow changed my df for the first time post and am now curious. I have 45 k on on 08 unlimited rubicon not sure if it has ever been changed So thinking I should what should I use I off road some times some times more than others and I have the factory lockers. What ever I do I want it to be an upgrade> I don't tow. but sometimes the jeep is really heavily loaded. so what do you guys suggest?

 

Mobil 1

 

oreilly syh 9 dollars a quart

 

Mobil 1 75W-90 in both if you don't tow. Use Mobil 1 75W-140 instead in the rear if you do tow.

 

Royal Purple 75W90 for me. The best in my opinion. Definitely take a look at your diff fluid, I did mine at about 20k miles. Really easy fluid to change and you will notice a difference in driving.

 

Royal Purple 75w90 for me as well. It is insane how easy it is to do the change yourself, especially with the JK having drain plugs so you don't even need to crack the seal on your diff.

 

X3 on this. RP is the best. I use all their products in my jeep. Coolant, oil, power steering, transfer case, diffs. Jeep runs smooth... Really a noticeable difference.

 

Used Valvoline 80-90, dealership said they come with and add a non-synthetic oil

 

 

YES! Another oil thread!

Amsoil if it is easily available in your area, if not Mobil-1.
