Land rover recomends Texaco Cold Climate PSF 14315 but... You might know that Cheveron bought Texoco and Havoline, I picked up some Havoline PS fluid (Amber in color) the other day, it also had the Texoco symbol on the label. I've had a heck of a time with a moaning noise ONLY when I turn my DIsco to the right when she's warmed up. I also have a slight viberation in the steering wheel around 35 mph then goes away. 3 power steering flushes, 3 quarts of Vavoline Syn, and 2 bottles of lucas later I'm right back where I started. The Val Syn is not amber in color, if memory serves me it's clear yellow. I can say this. I put the Havoline PS fluid in (LR Recommended) and I've not heard the sound in 24 hours, keep your fingers crossed!
