Anyone used DOT 4 LV brake fluid in their Infiniti ? I know it calls for DOT 3 but DOT 4 is backwards-compatible and LV fluid claims to work better with ABS as well as provide a better "feel". My wife's car requires DOT 4 LV so I'll be buying some and wouldn't mind using the same stuff in my G35.

I've no interest in DOT 4 because of "higher boiling points", etc, etc 'cause I don't drive in any manner that I'd even exceed DOT 3 capabilities.
