I have noted on a few replies to members, the reference >It
is Citroen LHM fluid< <

Liquide- Hydo-Mecanique. Green stuff that goes ito Citroen suspension
spheres.
I think it’s the same stuff as the castrol. It mixes with it, as I used it
for four years.
Cheers, Peter

Thanks Pete
I talked to Castrol about a month ago about 5966 hydro-oil…
They guard the technical data on this product like military
secrets. Castrol finally said that Castrol makes the product
primarily for Jag use and to go to Jag and get the info. I am
looking for a common ordinary “technical data sheet”. Since I am
unfortunately familiar with this type of information run
around–problem, I now have asked for a MSDS (Material safety
data sheet). I am not interrested in the propriatary make-up of
the product. I am just curious what it is that makes this stuff
so “special” from a performance standpoint.

Hi Dave and HSMO Enquiring Minds,

My Educated Guess and Professional Opinion (=$.02 cash value)

Mineral oil is a mixture of liquid hydrocarbons from petroleum. There are
light mineral oils, heavy mineral oils, and everything in between. The
composition any given mixture will determine its physical properties. The
compositions are, of course, proprietary.

All the manuals make a big point of using only the Castrol Jaguar stuff in
the car. This could be a specially formulated blend, or it could be Nujol
with green food color. It could be the same stuff they use in Citroens (vide
testimonia). To know for sure, you would have to do some chemical analysis,
have some inside information, or be willing to use your car as a substrate
for equivalency testing.

The hydraulic system on our cars is pretty complicated. Maybe the only thing
special about the Castrol Jaguar stuff is that it has been filtered so that
there are no particulates to gum up the works. Or it could be something else.
Even if I found out that the physical properties listed on the MSDS were
identical to those of Nujol (or any other mineral oil), I wouldn’t risk using
it.

I know it is a pain in the neck to track this stuff down when you need a
bunch of it in a hurry, and it’s not particularly cheap, but I’m not willing
to use anything that doesn’t come in a bottle with a little paper sleeve
around the neck that says its for Jaguar hydraulic systems in seven different
languages.

I assume this is just idle curiosity. The stuff from Castrol is
available from sources other than the dealer and is not that
expensive. After all, you don’t have to change it every 5,000 miles.
Doing a flush and fill every 2 years is probably fine.–
