I guess I have been out of the scene to long, because last night I went to order some 607 and it appears it's no longer on the market.

Anyway, what diff fluid is everyone using these days?

I think I'm just going to bite the bullet and go with the Amsoil Severe Gear. I also need some Synchromesh Friction Modified transmission fluid, so I much rather place an order with HTG and get everything from the same vendor.

 

Mobil 1 75W-90 in the diff and Honda MTF in the tranny.

 

Try the le1605 basically the same as the 607. You can get it from ricks.

 

I'm starting to lean towards this option.

 

Available everywhere. Well at least the Mobil 1 is and I'm sure you have a local Honda dealer.

 

im using mobil 1 for the diff!

 

A car that sits on jackstands doesn't need diff fluid.

Oh I thought this was a riddle. This is a serious question.

Redline 75-90W.

 

i run honda MTF in the tranny, i was running pennzoil in the diff but i will order the amsoil now since im trying to diagnose my diff noise.

 

I think I am running redline now with no issues. Gm synchromesh in the trans. Just dont use royal purple id rather use recycled oil in my car.

 

I used Royal Purple once and I wasn't impressed with it
