100% eflex here
No issues, car sits for afew weeks without been started, but always starts up first go,
I just change fuel filter when I do my oil service, it's cheap anyways so why not
I always cut the filter up when I remove it and it looks good to me, no unusual particles or anything
Catch can is always empty too,
I run a started thermostat so oil temp sits at around 85-90degrees to evaporate the ethanol and moisture from the oil
Oil gets drained every 4-5000kms and is never milky
