Differential Fluid - Dealer Recommended thoughts?
My honest opinion is that fluid will be on the thin side of the original SAE90 spec. Everything I've seen indicates that our diffs wear less with thicker viscosity fluids, 75w90 is as low as you should go, and this fluid is even thinner. I'd go with an aftermarket fluid approaching 110 viscosity, the high cost of the oem fluid makes the decision even easier. If you want to stick with Honda fluids you can get their 80w90 at a much lower cost.
At least the dealer did not recommend the VTM-4. That is for the MDX/PILOT differential which has almost nothing in common with the S or standard diff. The MDX type diffs have 2 electronic clutches and built in oil pump for limited slip and fixed gear motoring. Do not put it into the S.
