I run $6 quarts of parts store DOT3 myself. I can afford to bleed it yearly, but even so, DOT3 can absorb a lot more moisture than DOT4 so it is better suited to longer change intervals. DOT4 would be superior for track days I suppose, but would need to be flushed more often. The Ford Motorcraft brake fluid (the regular dot3) used to be rated at a very high boiling point for cheap fluid and was a favorite among road racers of street cars for a long time because they could afford to flush the fluid every weekend.
