Hi fellow coffee lovers!
I see Molykote 111 recommended by many, both here and on other coffee forums as the go-to lubricant for E61 groupheads. I myself used it a couple of times, but found it somewhat lacking (lever movement would be really smooth in the first couple of weeks, but then I felt an increase of resistance and on bringing the lever down - a slight squeak) and on a recommendation from another forum’s senior member, I switched to Loxeal No 4, a PTFE and silicone grease. I lubed the whole grouphead and it has made everything ultra smooth. No more squeaks or increase in lever resistance. I gather (but don’t know for sure) that ECM use Loxeal No 4 in their machines.
So I just thought I’d ask what your opinion is on the subject.
