I have an 02 Explorer sport with the 4.0 v-6 automatic and I am getting ready to change the fluid in the differential. The owners manual calls for 80W90. I am considering M1 75W90 and Amsoil 80W90. Which would be best for my application, or any other fluids? Thanks
Which fluid in differential?

Soonerfan, are you sure of the diff oil specs? My 2000 Explorer Sport uses synthetic 75W140.
The diff is a Ford 8.8", which is the same as yours.

My daughter's Explorer came with 75W140 factory fill in synthetic.
I use HDS-5 in 75W140 as a refill.

I'm not sure which diff I have, but I checked my owners manual and it specifies 80W90 for non LS diff. It also has a 2.9 quart capacity which seems higher than average. This diff has only one add plug and no drain. It must be pumped out. This is very different than my 4 door explorer which has a drain plug and specifies 75W140. Would using the 75W140 where 80W90 is specified have a noticable effect on MPG? Thanks
