I am one of those people who advocate only Honda brake fluid in the Euro, because of the seals. It's good enough for street too. I bleed a little bit of fluid out of the calipers every year just to get any overheated stuff out. Maybe it's just my paranoia and using any other brand of equivalent DOT3 or 4 fluid is fine. Although, I have read somewhere that high performance brake fluids like Motul RBF600 can swell the seals if used for long durations (years) and that is a DOT4.
I'm sure there are many others who will flame me for trying to let Honda profit from us, but there are only 2 things that I will stick to Honda OEM for, which are the coolant and brake/clutch fluid.
