OK gang it's time for my first oil/diff change after break in. I've read the posts and looks like Shell Rotella 15w/40 would be a good fit for my area and machine. Question is can I use that in the diffs as well or do I need to run something heavier? Service manual says 15w/40 SG or 80w/90 GL.
Let me hear your opinions.
BTW I ordered a UNI air filter as well and will get that installed next week once it gets here.
Thanks
I run 80w90 in mine during the winter with no issue.
I HIGHLY recommend using a hypoid gear lube.
the 15w40 is a great choice. It offers the best protection for these motors, especially since the internal bearings used arent the best.
If you can, go with the TwinAir + The Prefilter vs the Uni. I have had much better luck in my personal one. The uni seem to get dirtier quick and requires more frequent services & cleanings.
