Ok, so this bloody thing's drinking 30 quid of LHM a week :evil:

Surely I can use oil (which is a damn sight cheaper) while i'm waiting for an octopus fix???

Thoughts?

vegetable oil will bugger things up big time, but i would have thought a straight mineral oil would work on a temporary basis. Though you still might bugger up your break seals.

If it were mine i would try custard mixed with barrs leak fix, proper Birds custard mind, none of thet cheap stuff.

Hydraflush is cheaper!

I resorted to alternating between LHM and cheap 20W 50 oil in my GSA when a rear susp cylinder went. It eventually became completely incontinent though. If only I'd realised earlier that it would hold if the car was in intermediate height, it would have saved me a trip on a low loader and a slick of fresh LHM all over a motor factor's carpark :oops: . I was later able to drive all the way from Woking to Chevronics in Bedfordshire and it didn't spill a drop!

But yeah... ^^ Hydraflush would be cheeps, but if it's really pissing out.... what Bandit said!

Mark.

Hydraflush is £20 for 5 litres, ish. Hydraflush is simply aviation hydraulic flushing fluid, so it stands to reason if you bomb off to an airport and ask nicely then they should be able to get you something alternative.

Oh, 25litre drums of LHM are only £40, which is pretty cheap imho.

I'm pretty sure that as both MI5 & the FBI are watching every word we type these days you can expect a knock on the door very soon for mentioning BOMB and AIRPORT in the same sentence... [coat]

Where you getting your Hydraflush from at that price? And your 5gal LHM for 40 notes?

Hydraflush I last bought from Pleiades. LHM comes from GSF, its special order and usually the store will deny its existence, a quick call to head office usually changes there tune. I don't have the GSF stock number any more either.

Failing that, call Total, they've ship a 200 unit pallete of 1.5 litre bottles for about £3 a bottle.

Morris oils do 5ltrs for 'quite cheap' if you can find a local but decent factors. In fact, I think it works out cheaper than hydraflush from GSF which is £20 + VAT for 5 ltrs.

20 ltrs LHM+from GSF is £69.33 + VAT sir! = £3.47/ltr
5ltrs Hydraflush from GSF £23.15 inc VAT = £4.63/ltr
1ltr Morris LHM from GSF is £4.64 inc VAT/ltr
1ltr LHM+ from GSF is £5.29 inc VAT/ltr

I rekon if you find the 5ltrs of Morris LHM it'll be cheaper than Hydrflush

Many years ago in the dim and distant mists of time...............

Citroen in the manuals for hydraulic cits (CX's G's, probably LHM D's etc etc) used to say in an emergency you could use straight 30W oil as a substitute.

But that it was to be flushed and refilled with LHM at the earliest opportunity.

Well, i've now stuck a couple of litres of 10w40 full Mineral oil in it and (most likely due to the viscosity) the leak has all but stopped. There's also been no abnormal operation all day.

I know there was some particular concern about the brake seals, but after some research earlier it appears that, though not desirable, pure mineral oil IS compatible with the seals.

Besides, I figure that as the brake lines are dead ends in the system it's not likely it'll actually reach the calipers unless they're bled through.

So, unless it starts doing anything weird it'll last a few hundred miles i'm sure! (Failing that, there's always Dexron).

LHM is mineral anyway so I cant see a problem.. Buttercup Bob's been running his D on fucking sunflower oil or some shit for years...

Whereabouts is this leak J, O/S from the front subframe?
If it's arsing out that much I'd say it's got to be an operational return from either the rear or front HC..
Most likely the short cunt of a pipe off the front HC..?

WARNING!!!!!

We must make it clear at this point, that very early DS and ID cars, use LHS, similar to BRAKE FLUID, and NOT LHM.

Buttercup bob, who has a 1955 slough DS19, uses a mixture of canola oil, and brake fluid.
I can't stress strongly enough that people with LHM cars like ours, should NOT use this stuff!!!

I'd advice against ATF; it contains 'friction enhancers' which won't do the fine tolerances of the hydraulic components much good...

D3 would probably be ok, there's fuck all good in it for autoboxes!
