Yes, the confusion comes about because of people confusing silicone (DOT 5) brake fluid with synthetic brake fluid. Basically all DOT 3, 4, and 5.1 brake fluids are synthetic and are glycol-ether based, whether they are labeled synthetic or not, and can be mixed. DOT 5 is silicone based and cannot be mixed with DOT 3, 4, or 5.1 glycol-ether based brake fluids.
