    Does your car spec it? Mine definitely doesnt, but I used it anyway to avail of the higher boiling points. Seems fine, though Ive heard of others reporting problems with 5.1.

    Not progressive. Seems to fade fast.

    Same in a gsxr6. A hyundai coupe. Renault trafic. Nissan navara.

    And its not a bleeding issue

    Is DOT 5.1 not designed for race/ high performance cars. 1 race only?

    Are you thinking of DOT 5? DOT 5.1 is the glycol fluid standard with the highest wet and dry boiling points.

    I was under the impression that DOT5 is not compatible with ABS equipped cars?

    That's right, it's too thick. But we're talking about DOT 5.1.

    :o Just re-read it now!

    Surely there is not need to go above DOT 4 on a road car though?

    Hmm. DOT 5.1 does absorb moisture good-oh and is quite thin. Maybe it just doesn't suit your yokes in this climate?

    There isn't. But "need" has nothing to do with it. Aside from the Need For Speed. :cool:
