I use the Mobil 1 in your first link for both front and rear.

You could probably get away with the Valvoline on front and rear as well.

I was going by the owners manual.It says rear diff use 75w90 synthetic and front 80w90 but doesnt say to use synthetic for the front.Advance auto didnt have 80w90 in mobil 1 or sythetic!!Thats why im using valvoline in front and mobile 1 on rear!Is it ok to use?

When i read in my manual that the rear diff uses 75-90 and the front 80-90 i contacted royal purple to ask their opinion.

They told me it`s perfectly ok to run 75-90 front and back so i did. It has been 15k since i changed to the 75-90 with no problems at all.
