My contention is that the pan should be laid out so that I can pull the plug and drain ALL the oil out. For the person that maintains their own car after the warranty period, I want to be able to remove ALL the oil to prevent more frequent oil changes.
I am a stickler about my oil drains because I want MAXIMUM engine life and when I do take that engine apart I want it to be COMPLETELY SLUDGE FREE.
I agree 100% with the above.
I usually "waste" 1/4- 1/3 quart of clean oil to flush out the bottom of the pan. It tends to kick up any particulates and trapped old oil and push it out. I guess this too could fail to depending on the config. of the pan, but I always seem to see some junk push out using this method.
