Interesting. Mixing Dot 3 and Dot 4 is actually not a good idea according to AI.

Quote:
Yes, DOT 3 and DOT 4 brake fluids can be mixed because they are both glycol-based and compatible. However, mixing them will slightly lower the overall boiling point of the fluid compared to using pure DOT 4. While DOT 4 has a higher boiling point than DOT 3, mixing them doesn't cause any chemical reactions or gelling issues
