This is not rocket science. Pull a plug, watch the oil drain, put the plug back in. Remove oil filter, put new one on. Pour in the required amount. YOU ARE DONE. 30+ years I have been doing this, never checked the oil level afterwards...because i just poured in the exact amount THE FREAKING MANUFACTURER told me to put in. If any of you messed up one of the incredibly simple 5 steps above, and want to check to make sure that the oil that you just poured in made its way to the oil pan, then by all means be my guest.
