chainsaw oil. bike shop laughed, then his chain snapped on a climb
Lube has nothing to do with whether or not your chain snaps. Snappages happen on the plates, which aren’t what wear when you are riding in crud.
I was searching for a chain lube that would not leave my chain covered in crud. In the summertime, only the white lightening dry stuff would do that BUT it only stayed on the chain for about 2 hours, which is shite really. Some pedros stuff in a spray can wasn’t bad but still didn’t last very long.
For wet rides, I was using WL wet stuff but I’ve discovered that finish line is way better and lasts longer.
And I really think finish line is thicker and stickier than engine oil. If you want to be creative with home-made lube, try PTFE grease (the jelly-like stuff) mixed with a bit of oil and a good dollop of vulcanising rubber solution, to make it sticky. It works very well 🙂
