ANyone have anything bad to say about Valvoline Synpower brake fluid?
<center><img src="http://www.valvoline.com/images/products/bottom_057.jpg"></center><p>Synthetic formula brake fluid in a 98.5 audi a4? I searched but no one really replies to this kind of post with real info. just saying they have it or they have never heard of it or that it is 4.99 a big bottle. I want to know if I should or shouldn't use it. Online reviews say it is one of the better off the shelf fluids to use for ABS systems.
Please help

In my car now... works quite well, and can't beat the price. I would recomend it...
I need to bleed mine, but I have 3 track events on mine, a total of about 300 track miles, plus regular driving... on 996 Porsche brakes.
I will be putting more of it in there.

I use it, no problem after 4 months of usage. I believe quite
many Audi owner uses it (cuz of the cost and easily purchase from local store). Should be decent for street riding

I used it for a long time, and recommend it for the street but *not* the track..
It worked just fine for me on the street, and I recommend it for all the reasons that others mention: price, availability, and wet boiling point.
After using it for ~15 track days though, I decided I don't like it for the track. After a particularly hard-braking session, the pedal would get a little mushy, and that mushiness wouldn't go away until I bled the calipers. I can't believe that I was actually boiling the fluid, because I never had any "oh ****" moments, but it was perplexing that bleeding would fix the mushy pedal.
So somewhere along the line (maybe on the AP Racing website???) I read that if a brake fluid has too high a viscosity, that it can be subject to frothing from heat and pressure-cycling. So I switched to Motul RBF 600 for the track, and the mushy pedal hasn't returned. I don't know if this reasoning really explains it, but the Motul does seem to be lower viscosity, the pedal is firmer, and I've had no frothing/foaming/boiling of fluid.
YMMV. I'd say that 90% of the guys that I know that use it on the track are perfectly happy with it.
