Hey, I just read this thread on sunday, and read what Pittman said, and then monday, I was practicing in a room, and there on the piano was a very old bottle of AliSyn oil. It looked like it was at least 10 years old, because the oil was pretty yellow, but taking it to be a sign of fate(I have a 1 year old Yamaha YEP642-S with tight valves and I've been pretty unhappy with my oil choices so far), I immediatly cleaned my pistons and valve casings that night and tried it, applying only a few drops to the bottom of the pistons and then working it in. So far, I've had the most consistant valve action ever on that horn, especially on my somewhat problematic 2nd valve. I talked to my teacher, and he said he also used to use AliSyn for the summer when his pistons got swollen up, and condoned, so I just ordered a bottle of it from WWBW. So to answer your question, yes they do still make it, and yeah, I think it's awesome too. A little pricey for such a small bottle, but considering how long it lasts and how little you use, I think it'll last for a long time (####, this bottle looked like it was from the 80's, and it was still 1/3 full).
