Good point. Some of those instructions are meant to guard against
accidental overfilling by people who check their oil right after shutdown,
but I suppose there are automakers who have engine designs that demand the
consideration of different criteria.
This must be a Mercedes or BMW or something else on the exotic side of
things. I was thinking of a run-of-the-mill Japanese or American 4-banger
or V6, with an oil capacity of closer to 4 or 5 quarts.
That's true. But most dipsticks I've personally encountered were graduated
to show one quart, or one liter, between the marks. Again, I'm sure there
I doubt that back in 91' whatever he's got is as critical as mine. I'm not
at all sure that mine is as critical as MB makes it out to be. It sure
scares the snot out of you when every other line says something like "will
damage the engine". There is a sticker on the oil fill that says that the
use of other than specified oil will damage the engine. In the U.S. there is
a choice of one oil I can use: Mobil 1ESP formula M. Try finding that on the
shelf of your local Walmart

If you checked it right after it was running for a good while it could
appear 1/2 quart low. After it sits for an hour and cools down the oil
from all the passages and the top of the heads and oil filter will run
back down into the sump pan and the level may check normal. This is one
reason there is a normal band on the dipstick. I the level is below that
band it's usually a quart low. If you are really worried drain a little
from the drain plug. But first, consider the scenario I set and if it
matches your turn of events, don't worry about it. If not, just drain a
little out. And depending on the motor and length and width and depth of
the oil pan 1/2 a quart over may not equal a significant rise in the
overall level with the engine running.
If I check my oil and try to check it again I cant unless I wait a
long time as the curved dipstick holder gets coated with oil and shows
higher than it is, check it tomorrow and 1/2qt wont hurt anything, it
might cut your milage a tiny bit, but to do damage you need to go more
than 1 qt over, like 1.5-2 qts, and this depends on the motor, if its
a big v8 it can hold 2 qts over alot easier then some 4 cilinder
motors, the motor is just bigger and the oil wont raise up as much.
You loose mpg when the crank gets covered, and damage occures when it
slaps into the cilinders, but you might need more tha 2qt over to have
that happen. Figure this, when motors all had carburators serious
flooding could occur that could flood the motor with a quart of gas,
sure it would cook off but it didnt kill the motor.
