Hydraulic jack oil

[Migmac]

My trolley jack needs topping up with oil, first time in two decades. Is hydraulic oil the same as hydraulic jack oil? I can get the hydraulic oil free, being a Scot a fiver in my pocket is better than it being in some one else's

Yes it's fine to use the hydraulic oil.

Jack oil is just machine mart's way to commit robbery, it a hydraulic jack, hydraulic oil is what you need.

Not just machine mart, Halfords as well.
One of my old trolley jacks we took to Iceland was topped up with brake fluid, still going strong.
use hydraulic oil it will be fine.

If you were closer you could have a 20 litre drum of the stuff for nothing , its been sitting here forever and a day , filled the pipe bender with it , egg cup full !

The question is, after 20 yrs, where's it gone? Might need a seal kit too.

Is it not achieving full height or has it stopped working?

If it's just not achieving full height it's more than likely just vapours that have been lost out the breather over the years.

It's not getting full height, took the fill screw out and the oil level is down a bit. No dampness anywhere so I'm presuming it's just a simple top up

Brake fluid works but needs changing regularly because it's hygroscopic. Things can go rusty otherwise.

Brake fluid will eat the jack seals. Avoid!!!

Dont copy (disclaimer lol) as ime just letting you know what i use with no issues..ATF

atf and power steering fluid is seal friendly

You might be interested to know then, that the brakes on a lot of tractors use ATF instead of brake fluid, however modern tractors with power assisted brakes use the back end oil (UTTO), but always check before hand as some use brake fluid, some ATF and some UTTO.

I've seen a few tractor brake seals that have swollen up and wreaked because someone used the wrong fluid, usually using brake instead of ATF.

 

[Bill Edwards]

Or the wrong kind of brake fluid - DOT in place of LHM for example.

LHM, CHF, ATF, super farm 10/30w , 32 hydralic, 46 hydralic, engine oil, they all work. ATF is a good mix between the jack not omeng crshing down when you release it under load but still been abel to push it down by hand when there is no weight on it ( with bottel jacks anyway )
