I used to use Motul, very good stuff, but when the ATE fluid is near half price I've been using that in most of my cars recently and haven't cooked it yet.

Does clearly say not for road use on the tin though, could that be an MOT fail?

My Datsun had the blue stuff in it, was okay 'til you really hammered the brakes. From memory according to the spec sheet it had slightly improved thermal stability over boggo DOT4, but not as good as the Motul stuff.

At near double the price, you'd hope the Motul is better. I've never had any issues driving hard on the various car's I've put it in. Whilst I'm sure the Motul is the one of the best, the ATE isn't far behind.

Stumbled across this whilst looking for other things, page 9 has a brake fluid roundup.
