Getting ready to replace my power steering fluid (02 Disco) and research on this forum gives conflicting advice. Some insist that ATF should or could be used and some say power steering fluid.

I've even been told in passing by a mechanic whom I trust to use ATF because "regular power steering fluid will rot out the seals." Never had a chance to ask him about that statement and as far as I know PS fluid is what's been in there for 146k.

I think I have to go with PS fluid (Lucas) since that's what Rave tells me to do. Am I missing anything obvious?

 

I use regular lucas ps fluid with no issue. I use it in ace system too

 

Just checked with my local O'Reillys and the're selling quarts of Lucas PS fluid for $23 each. Ouch.

According the high mileage sticky here, I'll need four quarts. Oh the pain.

 

I used good ole Prestone power steering fluid at 24 canadian dollars a gallon. No issues after three years.

 

I used Valvoline with lucas additive.

 

I went with the Prestone power steering fluid also. No issues.

 

ATF, same stuff 'cos they'll charge you more for PAS oil and it's the same. Ripoff oil companies like additives companies.

 

My catalog is calling for this: PENTOSIN Hydraulic System Fluid 975 54001 348 | OEM Part Haus

Or this: FEBI Hydraulic System Fluid 975 54001 280 | OEM Part Haus

 

I've been using Pentosin fluid, it seems to work really well. Pump runs a little quieter with it.

 

I use Royal Purple full synthetic Max Ez for the last 6 years and a half bottle of Lucas power steering stop leak. Its been great and does not wear out seals and hoses. You can find it locally @ O'Reilly Auto parts or Pepboys only.

I'm about to exchange the fluid and rebuild the power steering pump this weekend.
