Power Steering Fluid
Honda PSF only. The 2010 Odyssey is hydraulic-assist — the wrong fluid makes the pump whine.

Why it matters
Honda PSF has a unique friction modifier. ATF or generic PSF can glaze the pump and rack.
Shop notes
Check with the engine off and the fluid cold.
A groaning pump on lock-to-lock is often low or oxidized fluid — service it before the pump fails.
This is a top-off / exchange item, not a rack replacement.
