4.2qt Oil Sump Capacity???

[bg]

When I changed the oil on my '00 OBW 2.5l, I only poured 4qts into it and
always read to the full mark....that's even allowing for pre-filling the oil
filter when about 8ozs. 4.2qt oil sump plus 8ozs oil filter = 4.45qts. I
took the dipstick reading about running the car for awhile and then let it
sit for 5 minutes or so....always reads to the full mark. Any harm running
the car with almost 1/5qt low?

TIA....bgin

The car engine is fully protected if the oil level is anywhere between
the top hole and lower hole. I find my 2000 Forester 2.5L engine is
right on the full hole if I fill with 4 liters of oil including the
oem filter. 4 liters=4.25 quarts

Hi,

I've found very few cars that showed "full" on the stick with the
"exact" same amount the book calls for--they're either a hair high or
low on the stick (neither of which is a real problem, though one wants
to avoid overfilling more than a small amount.) IME, a lot seems to
depend how hot the oil is and how long one lets it drain when the change
is done. For example, if I do a leisurely change during the summer (near
100 deg F) immediately after a run up the 10 mile grade into town and
let the oil drain for an hour while I do other things, it will take at
least 1/4 qt more than a quick winter change when I may only drive a
mile or two, drain for 5-10 minutes, then refill.

As Ed said, as long as you're between the two marks, you're ok, though
I'm a bit fanatical and top mine up when it gets down 1/4 qt or so. But
my engine's got 357k miles and a bad leak I haven't gotten around to
fixing...
