Oil level mysteriously changes on dipstick

The PWC newsgroup is almost non-existent so I hope I can discuss this
here.
I own two, four-stroke, 2006 Yamaha vx110 sport pwc waverunners. Before I
started them up at the beginning of the season I checked the oil level and
they both "appeared" to be two quarts low of engine oil. They were both
sitting perfectly level and had not been started since last season. This
startled me but I added two quarts to each one so it lined up right on the
full line of the dipstick.

Then I ran them both and checked the oil afterwards and now they both
appear
to be two quarts overfilled, and I have to suck 4 quarts of nice clean oil
out of them.

I just want someone to explain where the oil was hiding when I
first checked them??? Makes me think the best time to check the oil is a
minute or two after engine shutdown.

Thanks


Mike,

That is the MR-1 engine with the dry sump... correct? If so your first
mistake was checking the oil when the engines were cold. Your second was
adding oil. ;-) I have the same engines in my AR230 ('06). The dry sump is a
pain because the only way to check the oil is when the engines are warm, and
right after you turn it off.

Remove the excess oil, and check your air cleaner. One of the bad things
that can happen when the sump is overfilled, is that oil will back up into
the aircleaner rendering it useless and possible dangerous. Those suckers
are expensive to replace as well. About $80 if I recall correctly.

I hope this helps.
