Idk whether or not to put dot 3 or dot 4 in my 2012 3.7 v6. The brake/clutch fluid is low and my clutch seems like it won't disengage so my car won't go anywhere... any suggestions or diagnoses??
I'm guessing that it's just DOT 4. Since DOT 4 can be mixed with DOT 3, it is legal to state that the DOT 4 fluid is compatible with braking systems requiring DOT 3 or DOT 4. It's sort of like the way that ALL squares are rectangles but not all rectangles are squares. You can use DOT 4 fluid in all brake systems requiring DOT 3 or DOT 4 fluid, but you can't use DOT 3 fluid in a DOT 4 required system. The newer Mustangs require DOT 4 because of the more robust brake systems used on them which requires a higher temperature fluid. My car has the typical 4 piston front calipers but the Shelbys and some PP packages have the 6 piston calipers. That's some massive stopping power up front!That sounds like it's a blend to me. I like the idea of it. It's like a DOT 3.5 basically.
