Just saw the SuperSyn, or whatever the name of the lowest level syn they have (20K one, 15K one, regular M1, then supersyn or whatever it's called) at a chain store. Can't remember if it was NAPA, Autozone, Oreilly's, or Advance. But it's still around. I'd just use SuperTech or QSUD or NAPA syn when it's on sale if that's the level you're hoping for.
