Power Steering Fluid

[candaceph]

My 2003 Boxster S calls for Pentosin CHF11S hydraulic power steering fluid. Are there any other types of fluids that can be used as well?

Thanks!

Where do you go to buy these fluids? p.s. I live in the boonies but do have access to the more common auto parts stores.

U might be able to find it at a local import store if not online!

Sort of; Swepco 715.

Someone will shoot me down and that’s great. I have a quart and have yet to put it in. Love to here why I shouldn’t. I believe the main deals with fluids in these cars is compatibility with rubbers (seals & hose) in the system, boiling and foaming. Boiling and foaming proof isn’t really an issue any more.

So it kinda boils down to the rubber. It shouldn’t surprise anybody that Porsche (like everybody else) sources much of their componentry. Indeed in Germany, it’s from a relatively small number of suppliers. I would be really surprised if Porsche doesn’t source rubber from the same place as Merc. and BMW. Can’t see any demands put on a Porsche that BMW doesn’t want or require.

Further, there are a very limited number of types of rubber used in all hydraulic systems (Viton, Butyl, to name a few)

My fave little German parts store of 20 yrs didn’t hesitate to recommend Swepco & has presumably sold it for Zillions of Mercedes, Audis, VW’s and BMW’s etc. and some Porsches with no complaints. Further , Google “Swepco Porsche” and you’ll of find zillions of apps for Swepco products for Porsches.

Now, if that doesn’t nail it, I just called a familiar builder/tunner of Porsche race cars and the like (turbo’s, SC’s, etc) and they use it for power steering…and other Swepco lubes for everything else…as do many. So if someone doesn’t shut me down with a good reason (someone who doesn’t use Porsche air in their tires), I’m putting it in.

You decide.

You bugger, I was writing a tome about Swepco, while you were posting. Thought I was alone. See above.
