Has anyone here tried the Lucas Upper Cylinder Lube? It's kinda like oil, but claims to lube the top end, comp. rings, and help keep the carbs clean and lubed(carbs need internal lube???

). I would like to see if anyone has had any success story with this stuff, or if it has benefitted someone in any way. I realize that this could be a sensitive topic, kinda like hi-test or regular unleaded, or dino vs. synth.
