I have been watching those actually, before I bought the saw.
it hasn’t leaked anything. But I have not actually cut anything yet either. I have only ran it outside a couple times, I checked the blade was properly oiled. I adjusted the oiler just a smidge. Looks like it only has about 1/4 turn of total oiler rotation adjustment left or right. So I barely moved it to help oil the 20” bar. I saw a good oil mark on my concrete when holding the blade about 2” inches away and revving the saw. I saw a tiny bit of excess chain oil run off where the sprocket was, and wiped that up. It had been sitting inside all night, no bar oil leaks.
It shouldn’t leak right? I hope it doesn’t. That’s gonna drive me crazy. I like my stuff super clean and well kept.
