Chrysler 2004 300M - Manual (Page 202)

The best time to check the oil level is about 5 minutes
after a fully warmed up engine is shut off or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings.
Maintain the oil level between the MIN and MAX
markings on the dipstick. Adding one quart of oil when
the reading is at the MIN mark will result in a MAX
reading on these engines.
