Anyone use this? I bought the Silca version. Applied 12 drops on a degreased and clean chain every 8th link. Spun the cranks backwards a whole bunch if times. Wiped with a rag. Took a 25 mile ride. Hearing some squeaks. Thought it could have been the derailleur pulleys. Took them out and lubed the top one. The bottom one has a sealed bearing and it seemed fine (spun smooth). Applied 12 more drops in between the others (i.e., now every 4th chain pin). Still squeaking somewhere. Beginning to think I need one drop per link. Sort of defeats the premise of this lube (12-12-12). Anyone else having the same experience?
