Can I use DOT 3 instead of DOT 4?

You can absolutely use DOT4 in place of DOT3 brake fluid.

Can I mix DOT 3 and DOT 4?

What is this? As both DOT 3 and DOT 4 brake fluids are glycol-based, they can be mixed without a problem but keep in mind that the boiling points will change. Make sure to not mix DOT 3 and/or DOT 4 with DOT 5 brake fluid as the latter is silicone-based.
