Leading evidence: 'Use pentosin chf 11s' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check boots' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
If you are having to top up the fluid you probably want to check for a leak and give the rack dust boots a grope.

LN say Redline is acceptable - check their website.Much easier to find & cheaper.

Suggestion
Use a flash light and an inspection mirror to look very closely at the top of the engine right below the a/c compressor, fluid could form a puddle there.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I need to top off the power steering fluid.
What's the consensus here, Porsche brand or anything from the local auto parts store?
If Porsche, do I have to get it from a dealer or is available from any other source?
Thanks.
Where is the fluid going? You need to check for a leak.
There is a failure mode that has a high pressure relief valve in a line fail and as a result the power steering system is over pressurized. This can force fluid past the rack seals. Early on there will likely will be no leak sign as the rack seal dust boots catch this fluid.
(I was at the dealer when a tech was working on a Boxster with this problem. He had the steering rack out of the car and on his bench and covered a boot with a shop rag and removed it. It came off with a "pop" and the rag caught the fluid.)
What usually happens is the power steering fluid level gets low to the point the pump gets noisy.
Usually by this time the damage is done and the pump, lines, and rack have to be replaced.
If you are having to top up the fluid you probably want to check for a leak and give the rack dust boots a grope. If they feel like cheap breast implants well, there you go.
I was wondering that myself. Kind of unusual for the fluid to be that low without a leak but I didn't see any signs of a leak. I'll check the boots.
Thanks.
Macster, I'm not the OP but I groped anyway. Then I realized I did not know the difference between cheap breast implants and expensive ones. Can you help?
