Uses for waste LHM

Post by CitroJim »

On Saturday, after bleeding my Activa Brakes, I was left with a rather a lot of very clean waste LHM. It seemd a shame to just throw it in the waste oil container I keep in a corner of the garage so I kept it in a jar.

I did wonder about filtering it and reusing it as it is very clean, only having been changed recently after a Hydraflush. Is this a good idea?

Last evening, a couple of new uses presented themselves. I needed to make up a replacement part for one of our grandfather clocks on the lathe and found LHM is a good cutting lubricant when turning and drilling :D On the clock, one of its weights was about to make a bid for freedom due to a collapsed pulley and spares are not available after being out of production for about 200 years :lol:

It also looks like it'll be an excellent lubricant for clocks as well!

Does anyone have any other uses for used LHM?

Old Fordson diesel tractors run quite well on LHM as fuel :)

My Dad uses it as chainsaw oil. Must remember to bottle up mine when I change it and pass it on to him, as he no longer has an LHM car :cry:

Chainsaws need REALLY sticky (Chainsaw?) oil to do the job properly, as do Mbike rear chains.

Better use it to run the car on (diluted with DERV of course).

LHM is a waste product from the oil cracking process - being a skinny thin oil not really suitable for anything else - but hydraulic fluid.
Lubrication properties are bad, unless the lubed part is constantly immersed by the fluid.

Use it only for its purpose - or burn it in your diesel :wink:

If your jack uses a mineral oil, I would say yes.

I've heard that some people would pour LHM into a tank (of diesel Xantia)...
With no troubles. Just like SVO/WVO.

I once dismantled the sealed epicyclic gearbox from a pressure washer, and it was filled with what was without any doubt - LHM!
Why the manufacturers chose it, I don't know, but lubricity must be sufficient for the job.

LHM is fine as a lubricant is a sealed system - like Citroen hydraulics (internally) but it is virtually useless for anything else as it doesn't hang around - ie it runs away and seems to evaporate rather readily (which is handy when it is spilt)

If you're intending to use the stuff as fuel I'd suggest that it is filtered carefully - and that it is not used if you think it has absorbed a substantial quantity of water. If the fuel system is contaminated or damaged - . . . .

Jim - why don't you filter the LHM (through paper towel - or even a disposable face mask) and re-use it. Good idea to keep it in a sealed container to keep the moisture out.

LHM Water?

Post by paulbx »

I thought an advanatge of LHM over brake fluid was its non hydroscopic - does not absorb water?

LHM seems to be doing a reasonable job in one of our grandfather clocks :)

I've found some brands of LHM to be very good at dissolving concrete.
Not sure how thats useful though.
