    I'm with Way on the Motul. Everybody seemed kinda gaga (technical word) when ATE blue came out. I tried it, and after the first time on the track, I dumped it and went back to Motul. Never been back, but have converted a LOT of folk out here in the NW.

    A big caution on high temp racing fluids - they are more hygroscopic than standard DOT 4 fluid, so change it at LEAST every year.

    Motul is great for the track, but i say overkill and too hygroscopic for the street. ATE blue is nice for street and maybe "light" track. I enjoyed it on my last car and it lasts. The valvoline synpower stuff is good cheap street fluid.

    If you use Motul and are actually using your car for track duty, then you should also already be bleeding your brakes regularly, as such you will effectively be changing your fluid as you go through the year.

    I never change all of my Motul RBF600, at least not all at once.

    Same here; usually try and bleed enough fluid to clear out the calipers and SS brake lines.

    Motul for the win!

    Bleeding is not the same as flushing, moisture transfers throughout the fluid degrading its boiling points dramatically. A once a year fluid change is a must when the car is subjected to high performance demands. Motul RBF 600 does indeed have higher boiling points than Ate Super Blue and Type 200, about 10% higher, but its hygroscopic properties are similar. All DOT 4 fluids have the same base, although some vary the amount of constituents to improve their boiling points. Spending twice the price for a 10% improvement in boiling points while reducing effectiveness by mixing with moisture laden residual fluid is wasteful on at least two levels.

    There is nothing damaging or evil about Ate Super Blue, it is exactly the same as Type 200 with the addition of a dye. Those that can use the 10% rise in boiling points will be better off with RBF 600, but given a complete flush with lower costing Ate might provide improved performance over tired 600.

    I used to alternate between Motul, SuperBlue and the Valvoline. Makes it easy to tell when you're getting fresh fluid b/c of the color differences.

    I just spent the weekend romping on the MINI on VIR's Full Course. No fade, no issues, first time on track sans Super Blue. If the common ones just aren't getting it done, check this stuff out.
