Changing my diff fluids , Is there any real advantage to running synthetic gear lube? other than the price? I have an aussie up front, I hear a lot of guys swiitching to synthetic when they install autolockers

If its a new rig you should be ok or new seals. Synthetic likes to go past older seals.

Synthetic is the only way to go. If you don't use synthetic your jeep will not run ever again. You must buy synthetic from me and me only. I sell it for a low low low cost of only $99/litre. Remember if you don't use synthetic, your heep, umm I mean jeep will never run right again.

Synthetic fluids are fine and dandy if you like replacing seals and have lots of money to waste on oil.

I have ran almost every kind of syn/semi syn fluids and to be honest, the only thing I have to show for it is less money.

The other reason I don't run them anymore is because when you are out in the woods, how often to you come across someone with syn oil ?

just my 2c.

You shouldn't have to change the seals...that's a wives tale. Syn oils are no more likely to leak than a conventional one. And they are compatible with ALL and ANY other oil

synthetic oils are all I sell and I've never seen synthetic kill a seal but in my own truck I still use regular oil its lasted over 30 years with petrolium in the crankcase and gears so why change it up

Swiched to synthetic noticed the tranny seemed better but both my diff seals leaked but I have no knowledge of if they where ever changed so could just be that they been working for almost 25 years. Watched dyno tests of trucks that have been switched and they say it adds horsepower but unless u do it urself u really won't know

I switched to synthetic couple of months ago and noticed a couple days later that my rear diff which had never leaked before,started leaking out of the pinion seal,coinsedance or smaller molecules??? :confused: if your rig is new go for it,if not get ready to change some seals.

screw it, Lordco wants 15 bucks a liter for castrol gear lube, I choose free from the bulk pump! I'll change it more often
