02 jeep Wrangler PS fluid.

I need to add some. The cap says to use approved fluid and I can't find the owners manual.

Any ideas what to put in it?

Valvoline Synpower, RoyalPurple MaxEz, and Redline are PSF's to try.
2002 uses MS5931 generic power steering fluid and not ATF.

Thx. I installed an inline auto trans filter on the return side today and needed to top it up.

The newer Chrysler, Dodge, and Jeep vehicles use ATF+4 in their power steering units. If it's red, then it's ATF+4. If it's gold, then any old power steering fluid will top it off.

If you do decide to change out all the fluid, I'd probably recommend ATF+4 to refill it.

I just use the Napa power steering fluid

It's not red. Was clear/gold when it was new.

If you want, you can completely drain the unit and refill it with ATF+4. It's supposed to give better cold weather performance (like that's an issue for you!), and it doesn't get as aerated and foamy as regular P/S fluid.
When I converted my dad's Dakota, the steering did feel noticeably smoother.
