Valvoline Synthetic is a good fluid and available at most parts stores and Walmart.
You might find that that Ford DOT3 brake fluid has a very high dry boiling point but does not qualify as DOT4 due to a low wet boiling point. It would be good for competition where the system is flushed often but not so good for a car where the brake fluid is never changed.quote:

BTW Heavy-Duty DOT 3 Ford Brake Fluid is supposed to be just as good or better than most DOT 4 brake fluids on the shelf. "Good stuff" is what most Mustang owners refer to it as.
It's one of the most hygroscropic of the bunch. I do an annual flush using Valvoline or ATE, I'd do a twice a year flush with Ford fluid.quote:

Here's more info about the Honda fluid, if you care.
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.
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.
Copper?Does Honda use copper or brass brake components? I have seen old master cylinders that were sleeved in brass, but I assumed they were retrofits. Sure a big surprise when you run a hone through them.
It looks like DOT 5.1 is the winner.code:
Dry Boiling Point Wet Boiling Point
DOT 3 401ºF 284º F
DOT 4 446º F 311º F
DOT 5 500º F 356º F
DOT 5.1 518º F 375º F
