If you want to get maximum junk out of the engine, don't do a cold oil drain. Running the engine to full temperature gets the bad stuff into suspension (most is caught by the filter) and more of the junk will drain out with the old oil if it's still hot or warm. I always change my oil after driving at least 30 minutes, preferably a long highway run... usually let it sit for 10 minutes first so the exhaust cools a bit.You could consider doing a cold drain on the filter or altogether. Don’t think mom or the Spark would know the difference.
I’ve always done cold drain. I understand that hot oil drain faster. But walk me through this hot drain “gets more contaminates out. “ You drive a vehicle around so the engine is hot. You shut it off and the oil settles in the pan for 30mins. All the contaminants are now in the oil, right? But then let it sit overnight - aren’t the same contaminants still in the oil the next day? They are certainly not crawling back up into the engine overnight… maybe some settles to the bottom of the oil pan, sure, but how much? Is it more than is left by using the same oil filter for more than one OCI? Is it signifiant enough to even matter?If you want to get maximum junk out of the engine, don't do a cold oil drain.

Most oil pans have a boss or flange for the drain plug, this boss is higher than the bottom surface of the pan. (This is especially true for pans fitted with Kumoto valves or similar devices.) So a thin layer of oil will remain at the bottom of the pan even after it's "drained," no matter what you do. Where do the contaminants settle when cold? At the bottom of the pan.I’ve always done cold drain. I understand that hot oil drain faster.

When taking an oil sample, it is good to do it hot because it mixes everything up so you get a good, even sample. Contaminants settle to the lowest point due to gravity and can alter results.
But how is one exactly “getting more contaminants out” with a hot drain vs cold?
Have found that 0W oils flow out real fast even when cold. Maybe a extra minute.I've done cold drains before, usually it takes a bit longer for the remaining oil drips to slow and stop. I used to let the car sit for around an hour on cold drains before capping the drain plug with new gasket.
On hot drains, I notice the oil flows faster and doesn't take as long for drips to stop, allowing for a faster oil change and filter job.
To what degree is this significant? I mean, arguably yes “more” is coming out but how much more? Considering the topic of keeping an oil filter on for more than one OCI - is it really a factor? If you’re planning on keeping an oil filter on for multiple OCI then I think arguing the difference between a hot and cold drain doesn’t make much sense.Most oil pans have a boss or flange for the drain plug, this boss is higher than the bottom surface of the pan.

Where do the contaminants settle when cold? At the bottom of the pan.
The physical movement of draining oil is not nearly strong or fast enough to drag the contaminants off the bottom of the pan, up over the flange and out the drain hole, especially in areas far from the hole.
If you drain a hot engine, especially one that's been run on the highway a while, the contaminants have been stirred up and mostly suspended in the oil... not sitting at the bottom of the pan. The oil contaminants will come out much better during a hot drain.
Is there a story about why its called that or why you call it that?I have a 2012 Dodge F-150* pickup.
*Somehow, it really annoys people when I call it that.
"Dodge F-150"?I have a 2012 Dodge F-150* pickup.
Change the oilI'm changing the oil in my mom's Chev Spark. I change it once a year because she puts only 1000 miles per/year on it. No joking. Is it ok to change the oil filter every other year? Plus they put that gosh dang filter right next to the exhaust canister up front and you can easily burn yourself.
