Hi, I've been having difficulty sourcing appropriate Castrol LHM following a leak developing on 14762 between the filter block and pressure switch to the rear of the vehicle resulting in substantial fluid loss. Is the Penrite LHM Plus product a suitable substitute, or should anything other than Castrol be avoided? It lists on the bottle as being suitable for Rolls Royce cars with plastic fluid reservoirs, Jaguar XJ40, etc so going by this at least sounds to be compatible. However, I am obviously concerned about using anything other than the recommended for risk of damage. Thanks, Al | ||

Alistair, Assuming you are in Oz, given Penrite in an Australian company I've always got mine from http://www.derek.com.au/castrol.html Normally has LMH it sitting on the shelf. Don't know if he ships. Stefan | ||

I use Total LHM Plus in my Bentleys and my Citroen. I have used LHM Plus from both Castrol and Total and have mixed the oils over the last 4 years with no ill effects. I have no experience of using Penrite. | ||

The datasheet for the Penrite product is here: http://www.penriteoil.com.au/pis_pdfs/4LHM%20PLUS%20JULY%202013.pdf It lists as being made to exactly the same PSA specification as the Total product you mention Omar. It does also specifically list compatibility with post 1980 Rolls Royce and Bentley. It's readily available locally and priced rather better than the Castrol so if others have deviated with no ill results over long durations I'd be tempted to give it a shot, at least in 14762 if not 25955. Thanks, Al | ||

There are only two manufacturers of LHM (now LHM Plus) and only two sites that produce it: Total owns one (the original) and BP-Castrol the other. They even sell to eachother from time to time in true Anglo-French co-operation. The products are identical. The other companies simply buy it in bulk and rebrand it. So, if it is LHM Plus the brand on the package does not matter. RT. | ||

By the way, this stuff is used in Jaguars, BMWs and several other vehicles with hydraulic levelling, as well as R-R/B and Citroens. Citis are moving back toward glycol brake fluids on more recent models incidentally. All Citi C5 braking systems use conventional brake fluid in the braking circuits for example. | ||

Beware of yet another hydraulic fluid LDS [synthetic based colour orange] this is in my C6 and other later citroens with hydractive 3 and 3+ suspension,supposed to last longer and requires less frequent attention. This may well be used in the RR Ghost etc. Tests on-going if it will mix with LHM or can be upgraded! | ||

Would I be correct in thinking that the new(?) LDS synthetic fluid is compatible with both LHM and RR363 systems? - subject to a complete flush and refill of course! Oh, and is it non water miscible meaning that any moisture can find its own 'level' in the pipework and just hang around there until/unless flushed out? | ||

"Would I be correct in thinking that the new(?) LDS synthetic fluid is compatible with both LHM and RR363 systems? - subject to a complete flush and refill of course!" Maybe with the LHM systems, not with the RR363 even though the LDS is hygroscopic. | ||

For UK owners, I've been using Halfords own brand LHM Plus since I got my Bentley Turbo R 1987 last year, can't remember how much I paid last time but with my trade card it was about half the shelf price. The system is probably more or less all Halfords now following pipe replacement, both pump overhauls and a complete bleed afterwards. Graham | ||

Diverging from original question a touch but my reason for fluid requirement was the installation of an impromptu green fountain under 14762 from a small section of pipe that passes through the bulkhead between the filter block and pressure switch towards the rear of the car on the left hand side. I've replaced the offending section of pipe and bled the braking side of equation at the top bleed point on the rear calipers for the effected no1 system. Is there anywhere else I should bleed as well given the location of this leak? From the workshop manual I gather no1 circuit is also feeding the suspension, but 14762 being a UK market early Turbo R seems to differ from the diagrams in terms of location of bleed points. Thanks, Al |
