I recently got a used car, and I noticed this past week that clutch fluid is low. I don’t know what kind of clutch fluid is in there, only that it is most likely DOT-3 fluid, per the manual recommendation. I bought some synthetic DOT-3 - can I add it worry-free without knowing exactly what’s alrea…

OK to Mix Synthetic and Conventional Brake Fluid?

All brake fluid is synthetic. As long as your can of brake fluid does not say silicone-based, it is likely the only change made to new “synthetic” brake fluid is the label.
