Have you tried the *search* feature? You can find out a lot of info there.

You can find stuff like this; https://forum.ih8mud.com/showthread.php?t=18528&highlight=synthetic

The factory reccomended wieghts are also listed in your owner's manual in the back. The center has a different weight that the front and rear.

Eric-

I think previous discussion here have indicated it is okay, and many guys do, run 75w-90 in all three. IIRC the manual suggest SAE 90 or 80w-90 for the center. Guess I was just thinking "by the book".
