dot 5

I used the purple military surplus dot 5 in my m37 for a few years, had to bleed the brakes at least 4 times to get all the air out. When I switched over to a Chevy master cylinder and disc brakes the lid on the mc. said use only dot 3,so I flushed the lines and switched to 3. Motorcycle mechanic friend of mine says Harleys use dot 5, he claims it has a much higher boiling point.
