Brake fluid ok to talk in here?

So I noticed my 5th gen cap says only use dot 3
From my understanding dot 4 is backwards compatible with dot 3
the only difference being it has better stuff in to last longer and not overheat ect.

My question is why did Nissan say dot 3 ONLY.
The fluid is freaking black btw so I want to change it. I don't think it's ever been flushed.

Dot 4 actually doesn't last as long as dot 3 from what I've read.
It does perform better though.
You can use either, but if I remember correctly you need to flush out absolutely all the dot 3 first.

Unless you track the car, use dot 3 IMO.

Just stick with the dot 3. You can get synthetic too if your picky but if its just a dd dot 3 is fine.

Like others said, stick with DOT 3. That's what I used when I did a flush.

DOT3 and 4 are 100% compatible, and DOT4 has a much higher boiling point wet and dry. ALL DOT3 fluid is synthetic BTW. DOT3 cars can use DOT4, but DOT4 should not use DOT3, just as a car should not have lower speed rated tires installed. Performance will suffer.
