No, it's not dripping that bad yet. I have extra cyls in stock, but there's some more life to be used up yet from this one... it's already a mess anyway.
No, change oil every other week, as in approx twice a month, I keep a mental log or I try to.
I use it quite a bit & with the pressure turned up, the oil darkens quickly from the aluminum oxidization. It'd be nice to get these cyls with steel barrels, the oil quality might last considerably longer & the scraper seal too.
