I just changed the oil on Cat's Paw (hull no. 627, Yanmar 4JH2E) this weekend at the end of the season. I use a hand
vacuum pump manufactured by Pella. It takes about 1 gallon, roughly thesame amount each time. I measure how much oil I have used by returning the used oil
from the reservoir of the Pella oil change system to the same one gallon container of new oil that I have just used to fill the oil reservoir of the engine.
After running the engine for a short time to fill the oil filter (the oil filter holds less than a 1/2 cup of oil) I'm usually right between the two lines
on the dip stick.
Removing the oil filter can be a bit messy because it
still holds about 1/2 cup of oil after the vacuum pump has removed the oil from the engine sump. Anyone have any good suggestions for protecting this area
during oil changes?
