A&G's Re: [Chrysler300] Convertible top oil

We've heard this before about brake fluid.

Anybody know why brake fluid would be manufacturer used over hydraulic oil. Brake fluid seems just plain dumb for all kinds of reasons, not the least of which is that it is hygroscopic for heaven's sake - duh... But we are not engineers. What do you engineers say?

Since it is available, today we guess that one should use top of the line true synthetic hydraulic oil but which brand and exactly which Spec.? On expensive to fix cars, people today are using more and more Red Line, Royal Purple, Amsoil and the like.

We are interested in reading what knowledgeable others have to say.

Sooo what should we do and why?

Well Dan, I recently had to replace the convertible top pump and motor assembly in my 300H covertible from Hydro Electric in Florida. The original had packed it in last summer while attending a car show where it couldn’t move the top up or down properly unless we gave it some manual assistance. I was expecting to get some kind of warranty from them but they said that it was too old and wouldn’t cover it! I told them that I had purchased the assembly years before restoring the car but they didn’t buy that.

Now getting to what oil to use, I prefer using power steering fluid as it is colorless and less likely to stain anything if you should develop a leak in the system. The replacement pump and motor received from them was already filed with automatic tranny fluid (the red stuff). Some of the early cars used power brake fluid which would be a disaster if a leak should occur.

Why would you want to replace the oil in the system in your 66 300? I could see doing so if it looks like it’s dirty or?

Cheers from Fern with silver/lilac 300H convertible located in SE BC

Hi all:

Can anyone apprise me of the best oil to use in the hydraulic lift of the convertible top of my 1966 300? Should I purge the old oil? If so, what liquid should I use for purging?

Thanks.
