Most all DOT 4 fluids are compatible with DOT 3, DOT 4 Plus (also called Super DOT 4), and DOT 5.1. They are pretty much all glycol ester compounds.
Take a look at this website and you'll see there is only about one of the listed fluids that isn't compatible with DOT 3:

In the info on that site a couple of the fluids have an *, indicating they shouldn't be used in brake/clutch systems with magnesium, but our Vette system doesn't have any magnesium lines or caliper parts in contact with the fluid.
Don't ever use DOT 5!!!
DOT 5 is silicone based, not compatible with the other glycol ester fluids, and is not good in modern ABS brake systems.
