Hey guys, I'm going on a 4 hour drive pretty soon and I wanted to change out the oils in my diff, t-case, and transmission. I've done some research and read some forums about other evo owners using other brands either than Mitsubishi OEM fluids. I went out and bought some Amsoil 75w90. Can I use it all for my t-case, diff, and transmission?? Thanks in advance!

Tcase and rear differential use the same oil - transmission different.

You need a GL5 synthetic 90wt (so 75w90 or 80w90 will work) for the tcase and rear diff. The trans requires a GL4 synthetic. Amsoil makes a 75w90 GL4 that works awesome.


For amsoil you should be using:


This in the tcase and rear diff. You could also run the 75w110, or 75w140 version of this: http://www.amsoil.com/shop/by-produc...?code=SVGQT-EA


And this in the trans: http://www.amsoil.com/shop/by-produc...?code=MTGQT-EA
