I decided to check the oil level on the small 4 gal. CH compressor I
bought a year ago. I had added about 4 oz. (150ml) a short while ago
but today noticed that it was pretty much out of oil. I only use it for
tires, cleaning the garage etc.
How much oil do these direct-drive jobbies consume anyway? After all,
they don't "burn" oil like gasoline engines do.
Should I just top up with 5W30 synthetic engine oil?
BTW, I was reading the sight glass wrong. There was "too much" oil in
the pan, and the whole sight glass was covered.
I decided to pour some out. Looks like one should pay attention to the
manual re: changing oil after first hour or so of use. The oil had lots
of tiny black particles in it, presumably filings etc. I emptied as
much as I could and refilled to the proper level.
I'd go with the second model because of the wheels and
telescoping handle. I wouldn't use it to blow dust from my
computer keyboard, though. It should handle the light tasks you
have in mind, too.
