I would like to change the diffs, t-case and manual transmision fluids. Amsoil seems to be the fluid of choice but which one should I use AGL, FGR or SVG...? I assume I can put 75W-90 in all 4 places..?

My runner is 9 years old with only 37,000 miles. I am the second owner, first had it for 3 years and 11,000 miles. As far as I know the fluids have never been changed...

What is everyone using, how much of the stuff do I need and who's got the best price...?

Thanx,
nj

 

I use SVG in mine, 75w-90 will work in all places.
