What type of fluids are you running?

[Rockinwrangler]

I thought it would be interesting to see what type of fluids you old timers recommend.

I am running:

10W-30  Castrol  GTX in the motor

I am running:

Mobile 1 Synthetic 90W in front and rear diffs.


I also would appreciate some options on the best grease to use in the ole zirks....

Quaker state 10w-30 in the engine

Royal purple in the trans and transfercase

90W in front and rear diffs

As far as lube for joints etc. I am not sure what was used on mine. I took it to a buddy and need to get a grease gun so I can do it myself.

Advance auto parts oil 10-40 thru 20-50 depending on the weather. I've owned and sold about 1000 cars and never had an engine oil related problem that I'm aware of. I'll be using it forever I think.

All synthetic in the YJ (red line) products.

All Dino in the XJ for now. Havoline

Usually Bud Light, sometimes Early Times. Just depends on the day

I just run Castrol dinosaur brand.

Didn't think about the other fluids but that would be Cruzan and Diet and a few Coors lights or Corona's thrown in for good measure.

whatever 10/30 in the engine. Usually castrol.

Castrol in the t-case.

Valvoline Synthetic in the diffs. $5 a quart!!!  I go through way too much of that crap to buy anything else.

Agreed.

It has been long enough from my last oil change that I cant remember what I use.... I know its a Black bottle and its synthetic blend and I believe 5w20 per the manual for both the Liberty and Wrangler. Last time I did diffs on the old JK i used Royal Purple but I will probably use a little cheaper brand this time. I got about 5k miles before the recommended diff fluid change. I hope to get new covers by then

[rockcrusher]
