I can’t believe people still buy lube. Smooth, quiet, CLEAN, easy to use. I just leave it in an old crock pot. 1 bag for the season. It did both my chain and my wife’s. I would do both chains together, every 500km. We each have just about 4000km. That’s 8000km for a bag. Never had to clean anything. Looks like the day we bought them. Also, zero chain stretch.
