RBF600 £10/litre? BUY IT! Think you mean £10/500ml or £20/litre? I got my last lot from Opie Oils, think it was around £13/500ml.
ATE comes in a 1 litre tin unless they have changed it, £16.50/litre sounds about right.
Ah yes, you are right, it was for 500ml. But it would be interesting to see how much it is in the trade - I'll ask the purchasing guys at my old work. If they can get it for a good price, I could buy a box of fluild if anyone else is interested? ATE comes in a 1 litre tin unless they have changed it, £16.50/litre sounds about right.

I don't know what colour tin ATE Super Blue is now, when I was buying it about 7 or 8 years ago it was in a blue tin. ATE TYP200 comes in silver tin I think, exactly the same stuff as Super Blue except it's amber in colour.
I remember trying to get some Super Blue from a BMW dealership just up the road when I was desperate for some (track day next day, bleeding the brakes and ran out) and they got totally confused when I asked for it until they found it listed as ATE "RACING" Super Blue
I have no idea if it's still the BMW OEM fluid though, probably not.
That'll be some serious braking to warrant using SRF on your mountain bike!
We take our bikes to the Alps, so they do get a little hot I remember trying to get some Super Blue from a BMW dealership just up the road when I was desperate for some (track day next day, bleeding the brakes and ran out) and they got totally confused when I asked for it until they found it listed as ATE "RACING" Super Blue

But they main reason was "Because we can"!

Does anyone have any experience of how often Dot 4 brake fluid will need to be changed given its water absorbtion qualities? I was thinking of the Motul RBF 600 for an E39 M5. One supplier suggested it would need changing every 6 months....does that sound right?
I was thinking of changing it every year....at worst, would every two years be unrecommended?
Thanks.
It all depends on what you use your car for.I was thinking of changing it every year....at worst, would every two years be unrecommended?
Thanks.
If you are only using your car on the road then the brake fluid temperatures are unlikely to get near to their boiling points within a couple of years. For peace of mind with a performance car and normal road use I recommend changing any brake fluid annually as do most people. BMW recommend every 2 years (like most manufacturers) and you could do that if you wanted and I have done in the past on an everyday commuting Golf using ATE Super Blue with no problems what so ever.
If you are using it on the track then you need to change it more often and is probably where your supplier was coming from with the 6 months change. Obviously 6 months is subjective, it depends on how often you are on the track as brake fluid also breaks down with heat.
If you are unsure when to change it or want to prolong the changing you could always get someone to test the brake fluid for it's boiling point, most garages should be able to do this easily or you can buy devices to test it yourself.

I do mine once a year as i mentioned, i think every six months is a bit much, a supplier would say that he want you to buy it from him, also would depend on how much milage you do aswell i suppose if your up and down the motorway everyday then maybe more often if you do 5k a year then just change it as recommended every two years or whatever it is!
Unless you live in wales then once a month lol.

Thanks guys.
The supplier was mentioning 6 months more as a way of talking me out of it (prob because he did not supply it) than trying to sell me more .
The comments about type of driving make perfect sense. Generally it is for fast road use with perhaps one annual trip to a track such a the ring which, in my view, is not that brake heavy unlike bedford.
My current fluid prob gave up the ghost on after 1 lap at bedford on a recent trip!
