Glad somebody finally brought this up.
I have a nine quart pan and remote
oil filter and cooler. It takes 10 quarts of
oil to completely fill the engine, filter and cooler when dry. The dipstick is at full, and when I drain the
oil, I get 7 quarts out. Now, when I fill it back up, it takes the full 9 1/2 quarts to fill the pan and filter. WTF!
The oil level on the dipstick is exactly where it was before the oil change. So how come I only get 7 quarts out of the engine (including the oil in the filter) and it takes 9 1/2 quarts to fill it back to the full level in the dipstick?
What am I missing? Does it every time!
