Anybody heard of LIQUI MOLY before? Just showed up at my local NAPA. Sounds like its decent but I have never heard anything about it. Any comments or users? I'd be interested in hearing about it. Either the 0-40, 0-30, or 5-40 higher end synthetics. And if you could compare it to something out there already...ie comparable to motul, or better than PP, not quite as good as PU. Something just like that.....thanks
