Just a passing thought to the community. When changing out the engine oil there is the extra quart that stays in the upper portion of the oil pan. After draining the hot oil out and by adding a quart of oil at room temp would flow down to the front of the oil pan and displace some if not most of the oil left in the upper portion of the pan. Would the cooler oil sink and cause the hotter oil to flow over into the side of pan with the drain? I am sure at some point that the temperature difference would be null.

When you add oil from the front doesn't it passes over the timing gears and
drains into the front end of oil pan?

I don't know which is why I said that "I am not sure".

Try leaving the drain plug out when adding oil, see if the
oil clean or dirty.

When I removed the oil plug again it did look dirty, but that could have
been a mixture of clean and used.

Bruce,
That is real good thing to not worry about.
There is also most of a quart that doesn't drain out of the heads, lifters, rockers, balance holes, not to mention the lube oil cooler. In engine building, this is called oil hang up and it causes no problems in most all engines. (Except in test labs that are trying to do precise lube oil consumption testing.) Our engines just have more that we know about because it is in one place.

Also as soon as the drain stream becomes 'punctuated' the plug and new pre filled filter go back on Since there will be more than normal dry time at startup, I want that residual film still present at first restart without a long drain down time. I disagree with leaving the plug out overnite to get out 'more' as some do on their vehicles. As Matt said it's still puddled in the low spots. Adding 5 quarts with the '1 dirty qt in the pan' it is so clean on the stick it's hard to read for the first few hundred miles. If there is a severe sludging problem, the pan would have to come off to properly clean out. My engine from the PO was that way and multiple changes didn't get it out till tear down where we scraped a pint of sludge out. Same theory with coolant. Just drain and fill every 2 years and the new will dilute the remaining old still in there and refresh the additives in the system.

It seems that one could remove most of the oil from the front of the oil
pan without putting in the extra drain plug. It would also require the
same 6 quarts of oil to be put back in if one did have the front oil plug.
