Sorry guys if this has been covered....

Planning on changing front diff. oil. Mobil 1 75w90 synthetic $6/qt. at autozone.
About 5k miles, 200 in 4x4.
Wondering from your experience if I should change out with dino for a thousand mi. or so to rinse out the "mustard". Guess cost isn't an issue since it really ain't much oil. Anybody past the second change notice oil looking a little cleaner?
Should I just put synthetic in now?

Anyone with ZF6 changing gearbox oil this early?
