has anyone ever ran Royal Purple fluids in transmission, t-case, differentials? any good results?

 

anyone?

 

I run their diff oil, I haven't had any problems with running it. So it seems to be working fine.

Can't comment directly on their other oils, but I have a buddy who won't run anything else in his Wrangler. He loves the stuff, not really sure why though.

 

i probably wouldn't run it in the motor, because 4.0 HO runs dirty period and i change my oil in my XJ every 2500 miles, but tr. case and transmission, and differentials could benefit from it. the tv show TRUCKS! said to gain 20 hp on 5.9 Dodge Ram

 

I used Lucas in my other cars

 

WEll synthetic lube is better. I run amsoil in my engine, trans, t-case, diffs etc. I even use their grease for my joints and such.

 

I run it in my transmission and have had no issues to date. I have used it in many other cars as well.

 

Once you go Syn you don't go back to reg. oil. if you do engine deterioration will result.
