What clutch fluid?

[2blackhats]

I gather its supposed to be Dot 4. Is there anything else I should know? Like engine oil is there mineral or synthetic, if so which should I use? Recommendations etc.
Thanks oh knowledgable ones!

use the best quality brake fluid you can find,it should have a boiling temp on it ,brummie on here does carbone lorraine stuff that is very good ,

You could stick 5.1 in it, I was told by the Fishmongers to avoid the silicone stuff though.

Also fully synthetic oil. I was going to be a cheap skate and put semi in it as I have a couple of tubs in the garage.

halfords own brand dot4 is cheap and has a good bp

Ok thanks chaps. Halfrauds it is then.

Halfords do a 5.1 that can mix with other makes and types, I have changed mine 5 times now in last 8 weeks (just reservoir) what colour is the old fuid? probably very black, takes quite a lot of changes to get it clear again, dont forget to buy a syringe to suck it out, makes life easier

One bleed of the clutch will refresh with new fluid.

There is no way to use a Syringe on the standard setup, for bleeding.

Simply replacing the fluid ion the reservoir with a syringe is not bleeding.

I just use Castrol Response, its a Dot 4 or something. Never have any clutch problems.

DOT rating means nothing, some junk yank rating. Go for boiling point, anything above 300C is where the good stuff is!

I wasnt suggesting it was bleeding the system, to bleed it it a nightmare if you have not got a car lift and still a nightmare if you have

It does remove all the stty black oil from the reservoir, then fill with new, then drive it for a month and take a look at the oil again, it will be black, I don't know how but all the crap that is in the system gradually makes its way back up into the reservior, changing the oil can only do good, after doing mine a few times after about 800 miles of driving between each change, its finally staying quite clean now.

hmmmm, I might try DOT5 then DOT rating means quite a bit, try sticking DOT5 in your brake system if you would like to find out more

OP do pay attention, 4 or 5.1. There is more to it than just BP there is the absorbtion factor, a whole host of things you can start comparing but when all is said and done they are all meeting the DOT standard. You can spend all day looking for the minute difference. Not saying the Halfords stuff is the best but its certainly the cheapest and if you look at things like BP and moisture rate guess what....
