Hydraulic oil in Boxster 2000

[oracle10g]

<_< What is this Hydraulic oil in the engine area (not in the trunk), next to the firewall and right behind the driver side? It has a plastic cap with a measuring stick about one inch long. Mine, in cold engine, does not show any oil on the measuring stick at all!! I'm trying to find out what it is so that I can buy the correct oil/fluid to fill it in.

I called the dealer and the one who works for the parts dept seems unsure and told me that it may be power steering fluid and it would cost $25 for a bottle.

My questions to you are:

1. Is this really the power steering fluid reservoir that I must fill it.

2. Can I use some other fluid (what type and brand) from regular car part stores such as Pepboys, etc... instead of paying $25 for the dealer and is it safe to use others than Porsche's fluid?

Thanks very much for your help.

1. Yes.

2. No. It is Pentosin CHF 11S, in the green can. It is synthetic and I do not know of a substitute.

It is about $25 or so dollars a liter. Unless you have a leak you just need 1 or 2 oz, but you have to buy the liter can which will last the life of your car. You can find it for less on the internet but then you have to pay for shipping.

At our local work on cars days someone usually brings their used can for the cars that need a sip. I buy it from a local import parts place that sells BMW stuff since it is also used by BMW.

ToolPants,

Thanks, you're the best. I wish I lived near where you are.

I'll probably get it from my Porsche dealer then.
