I found this some time ago, Ialso prefer Honda brake fluid:
Why must I use Genuine Honda DOT 3 brake fluid?
Genuine Honda DOT 3 brake fluid is formulated to minimize water absorption under all conditions.
It has one of the highest boiling points in the industry. That's important in sustained use such as driving on hilly terrain that can heat up brake rotors and calipers.
When tested in a mass spectrometer, Honda Brake Fluid had dramatically less dissolved copper material than the leading competitors, clear proof of superior corrosion protection.
Always use Genuine Honda DOT 3 brake fluid. If it is not available, you should use only DOT 3 fluid from a sealed container as a temporary replacement. However, the use of any non-Honda brake fluid can cause corrosion and decrease the life of the system. Have the brake system flushed and refilled with Honda DOT 3 brake fluid as soon as possible.
Brake fluid marked DOT 5 is not compatible with your car's braking system and can cause extensive damage.
