Try the Honda PSF.
it didn't show up as compatible on the lookup guide for those models

I wouldn't use it. I once had a VW that used that fluid, and when I first bought the car, I went about topping up all the fluids. Not knowing any better, I used universal power steering fluid (that had a GM rating among others) to bring the PS reservoir up to max.
Within a few miles the PS pump was making a ton of noise, fluid turned into brown/greyish milkshake color mess and caused some major power steering issues; effectively ruined the rack. Even after a flush with the proper CHS11S fluid, I still had random stiffness/locking that would occur when steering at slow speeds.
I learned the hard way that these fluids do not play well together. YMMV.

Gm has a TSB for using Pentosin CHF202 in cold weather. I think the tsb was for 08 and up. Does yours have rack and pinion?
Might check rock auto and compare AC Delvo P/N's for the pump and rack. If they are the same, I would think you would be OK. CHF is Central Hydraulic Fluid (I believe). The ones rated for power steering commonly Pentosin. I think LiquiMoly has a CHF line of P/S fluid as well as others.
Pretty sure they connot be mixed with other P/S fluids or ATF. (See 92saturnsl2's post above)
Really good Viscosity Index.
Not sure the difference between. CHF11S and the CHF202, but I think the 202 is becoming more commonplace.
