I don't think it matters much which way you do it as long as it gets done.

I drain the warm-to-hot oil overnight. You'd be surprised how many hours, literally hours, oil is still draining from the pan.
In the morning, I insert a cotton strip during the plug hole which is about 3 feet long, and allow it to soak. Then I remove it.
Every time I change the oil, which is every 3000 miles or 3 months (whatever comes first), I change the oil filter and refill with fresh Rotella Synthetic oil.

I drop the pan, swab out the cam cover, vacuum the oil cooler, and give the oil filter big wet kisses.

And to think that I have been accused of being anally retentive concerning oil changes.

I have for years, however, done overnight drains and Paulsen is right, it will drip for hours and hours even when hot. The last drops that come out are the sludgiest.

Don't let my comment discourage you. Keep on changin'!

I usually let it drain for "only" about 20-25 mins....

Fresh Mobil 1 5w40 synthetic and a Hengst filter every 5,000 miles.

I guess I'm anally retentive too. I drain mine overnight or all day on a Saturday. I've found what seems to have the worst sludge comes from the oil cooler. And since mine is not a daily driver, I personally consider draining to be a little more thorough.

I drain my oil every two years....about 30kmile OCI, and the filter every 15kmiles. I take the plug out, let it drain until the drips slow down to 1 every 5 seconds, put it back in, and refill with synthetic diesel oil.

My engine will last just as long as yours, I'll spend $80 a year less on oil than you do, will pollute less, and might save your kid's life some day.

However, I won't get the sexual gratification that you get when you do your little procedure. I'm weird that way.

I drain by removing the drain plug when the engine is hot, put a pan under and let it drip for several hours, I only put the plug back when it stops dripping.
On the filter housing I get in it with a rag and absorb about everything deep down that is visible from up top, when I put a new filter in the housing is clean and dry.
I change oil about or little over 2K miles, Delo 15/40 diesel rated.

Vahe,

Changing your oil at 2kmiles makes you a certified environmental disaster....sort of an Exxon Valdez in slow motion.

240Joe

You seriously run your oil for 30,000 miles??!?! Oil analysis will prove that that is definatley NOT a good idea, even quality synthetics can't go much over 6-7,000 miles in these older diesels without a serious amount of soot in them, which can rapidly increase wear when it gets to a certain point. I highly doubt your engine will last as long as one with more frequent changes. I do them every 5k, with synthetic oil and a new filter.

No, it won't.

What is your TBN after two years and 30,000 miles?
