I'm just curious ......................... If you've waited this long for a tranny fluid change, how's the diff fluid? It should get way more attention than the tranny fluid.

 

Amen.

My dif fluid was trashed at 4k miles.

 

If his diff fluid has 88K miles on it, I suspect it's gonna come out of there looking like mud.

 

no i change my diff and tranny fluid about every 3-4 oil changes..so its good..its just about that time again....i've been using red line fluids from my tranny and diff..instead of the honda...isn't it better than the honda fluid?

 

First, I don't recommend Redline Shockproof in the diff. I experimented with it and the oil analysis indicated this was NOT a good fluid to use in our diff. Other Redline products may be fine.
2nd, Honda car division has NO diff fluid for the S2000. They must get it either from Honda motorcycle division or get it from outside.
3rd, Honda MTF is being used in the vast majority of S2000 since the day the car came out without any problems whatsoever.

 

The stock fluid looks like mud after a few thouand miles, let alone 88,000. Ever pop a large cyst and see the fluid come out? That's what OEM fluid looked like when I "popped" the diff.
