Hi Scotty,
when I do oil changes, I do something I have not seen others do. After draining the dirty oil, I pour about 1/2 quart of new oil in an drain it straight though. I do this to remove more dirty oil from the system. This may be overkill, but it makes me feel like I’ve done everything I can to make the engine as clean as possible.
since I value your opinion, I though I would ask what you think of this oil change method.
thank you
You definitely didn't invent that idea, and yes it's overkill. That little bit of dirty oil at the bottom won't do anything. Just think of all the dirty oil still the engine, clinging to all the parts, and pooled up in the various places. Your oil doesn't need to be crystal clear, and even if it was, it won't stay that way for very long.

That's definitely overkill. Next time you go to a junkyard, try to find an engine that's been partially disassembled so you can see the state of the inside of the motor. They're nowhere near whistle clean inside. They can't be, burning gasoline is a dirty business. I found a piston in the local LKQ and the oil control rings were partly held in place by blackened oil. I had it cleaned and plated at work; it took powerful industrial degreasers to get all of the blackness from motor oil off. I wouldn't obsessively drip the pan until all of the oil comes out, either, just an FYI. My step dad used to do that to his 2014 Mustang, once he let it drip so long that the engine chattered for a few seconds before the oil got back to everything when he finished the oil change job.
Maybe the engine wouldn’t be that bad if the owner did oil changes like I do?
They just get dirty. A litte grime is normal, Scotty's mentioned you don't want to be OCD about cleanliness, consistent changes are good enough. This engine was a Pentastar V6 from Chrysler, which missing its heads. Scotty mentioned a while back that that Chrysler engine was known for problems with their heads, which explains that they were gone. It was a 2010 Dodge Journey.
Overkill 100%. If it makes you feel better, keep doing it. But it isn't making a difference at the end of the day.
