Q: Ok to mix Dextron II & Dextron III ATF's(?)

This is for the power-steering reservoir - NOT for an automatic tranny.

My PS reservoir's a little low (right @ the MIN lines) - thinking about topping it off, but I think the old standard (Dex II) ATF is in there.

Is there any problem mixing in the new Dextron III type, or should I drain off the old fluid first?

TIA.

Should be no problem. Most newer fluids are completely compatible with older fluids.

Thanks Eric - that's kinda what I thought. -Anyone else know absolutely, positively, for sure?

Dexron III is a quality grade one level further than the Dexron II standard...III meets or exceeds all manufacturers recommendations for II lubricant.

Ok, didn't answer my question directly, but maybe indirectly.

As I understand so far, type II & III are fundamentally the same except maybe for a modified additive package in (III), ergo, it should be no problem to mix them.

Thanks, all.
