Hey guys, I have searched around to see if I could find any info but can't seem to dig any up. Do any of you use Royal Purple or AMSoil in the transfer case, transmission, motor etc? I would think it would be a great idea but I want to know your takes on it.

 

I use Amsoil in the differentials and the transfer case because I know its a good tested product. I probably will switch out my transmission from synchro shift to amsoil later this year.

 

Torque converter? Anyways... AMSoil would be fine in the trans, but stick to Diaqueen for trans. case and rear diff.

 

I ran royal purple in my tranny and within 6 months 2nd gear synchro went out again.

I will only use the OEM fuilds from now on.

 

sorry, that's still from being a forum for trucks....lol, no torque converters for you. I fixed it, I meant transfer case.....lol.

 

Both companies make good fluids. Only time everyone recommends to stick to the OEM Diaqueen fluid is if you have an MR. Nothing else but Diaqueen seems to work well in the MR. If you don't have an MR, you'll be fine with using OEM, Royal Purple, AMSoil, Redline, etc.
