: ATE DOT 4 Super Blue - is it okay for an 06 STS with JE5 ?

01-11-13, 05:04 PM
I am in the process of replacing the front rotors and pads on my 2006 STS with the JE5 package.

I wanted to take this opportunity to replace the old brake fluid - which hasnt been flushed/replaced in a few years. I have some ATE Super Blue DOT 4 brake fluid and was wondering if it is okay to use in the STS. Seems like the manual calls for DOT 3 brake fluid and from what I understand DOT 4 exceeds DOT 3 specifications.

Wanted to get opinions from folks that have experience with the ATE fluid (or recommendations on any other brand of fluid). I am a rather vanilla city/highway driver and live in moderate climes (32F to 90F) and lots of rain :)

Thanks in advance for any advice.

Happy New Year 2013 !

yeah should be fine you can up to dot 4 in a dot 3 system wont hurt anything. dot3-4 is just there boil point.
