I use the blue stuff used in current Volvos, VWs, BMWs, etc. Works very well with alloy engines and lasts a long, long time.
I tried Evans and waterless and it leaked out of the weirdest places. Hose connects tight enough to distort the hose would have slow drips. I flushed it all out and went with the above. All the leaks stopped.
YMMV
