First change with magnetic drain plug

[wbwanzer]

Changed the oil in my '23 Santa Fe with 2.5T engine. I'm at 30,000 miles now. So almost 4800 miles ago I went with a new magnetic plug. Today I was anxious to see if there would be anything attached to the magnet. There was nothing. I'll take that as a good thing. I replaced the filter (canister type) with a Carquest Extended Protection (20,000) as Carquest seems to be liked on here. Refilled with Mobil 1 ESP 0W-30 as that is also well liked on here. ESP is what I drained out. I started draining pan and filter before lunch. Put the plug back in hand tight before lunch and pulled it out again after lunch. I'm always surprised how much more comes out when I do that. All in all it drained about an hour and a half. I'm comfortable with that.

So I'm set for another 4500 miles at which time (probably January) I'll Mighty Vac out the oil and leave the filter on so as not to be rolling around on the ground in winter.

If it dont come out in 5min it ain't coming out when I change it.
if the oil is so "contaminated/bad etc" change it earlier IMO.

When the stream turns to a drip, the plug goes back in and I move on. I also will use a filter a second time with a 1/2 quart stored in the galleries. The caveat is I change at 5,000 miles. The stored oil is good for another 5,000 miles.

I too like to let it drip out over an extended period of time. And like you said, putting the drain plug back in after the initial drain and coming back later and removing it again shows more oil than expected still coming out. Typically, after I put the drain plug back in, I'll do other things like wipe the bottom of the car down, lubricate the bushings, have a beer, or have lunch.

I don’t necessarily “wait” for the oil to drain. I pop the drain plug out, let it drain into my oil pan. Then, I climb out, get the oil filter, fill it with new oil, get my funnel and my oil filter removal tool, get a new crush washer, etc.

By the time I get back under car, take the filter out, clean the mounting base, spin the new filter on, it’s been 5-10 minutes give or take. A small drip of anything still happening. Plug goes back on and torqued. Done.

I used to wait a really long time when I was changing the oil, sometimes 90 minutes! These days I don’t bother waiting much more than ten minutes. The difference is only a few ounces anyway

When I get down to one drop every 3 seconds or so , I'm done .

When I had my sun visor replaced a few weeks ago at Mazda (South Charlotte) the car right next to waiting room was getting an oil change. Guy took the plug out and once the stream went down to just a trickle, he put the plug back in. Wasn't even dripping yet. In the end, it probably is fine, but made me shiver....LOL

"Ignorance is bliss!"

I have a new magnetic drain plug waiting to be installed.

 

[Fattylocks]

I'm surprised that the magnet didn't pick up anything.

I was too. But I'll take that as a good sign.

Get a oil analysis done that will tell you how much fuel dilution from the direct injection is happening, and any wear materials and tell you to things like extend or reduce time between changes etc. https://www.blackstone-labs.com/ here is a link to a sample from them https://www.blackstone-labs.com/wp-content/uploads/2024/04/Understanding-Engine-combined.pdf is good and https://www.speediagnostix.com/

I don't like leaving my engine without oil for any length of time. The chance of some mistake either not refilling, not properly tightening, starting with no oil, etc is not worth the unclear benefit of a very extended drain time.

My personal car also has a massive drain plug that drains the sump very quickly. But even in other cars, once it starts dripping I reinstall the plug.

I used to let it drip while I had lunch. Then after lunch install oil plug, new filter, and oil. I think that's ideal if you have the time.

However, my cousin now changes my oil and he doesn't have time to wait for it to stop dripping. He waits until 5 min after it slows to a drip. Then installs plug, filter, and oil. It's good enough. It's probably 5 minutes longer drain time than any quickie lube place waits. Even my certified mechanic only waits for 5 min of dripping. It's adequate, but not ideal, IMO.

Who's going to drive it off when the hood is open and front of car is jacked up on a floor jack and has jack stands under it?

 

[lawrencerd]

Well, my car is typically on ramps, and if I was going to leave it for a long time I'd probably close the hood. But, that doesn't stop anyone from

-Forgetting to change the filter
-Forgetting to replace the plug before filling oil
-if the plug has been left finger tight as OP, forgetting to set the final torque

There's also some BMWs and maybe other cars that aren't meant for super extended drains from the sump and it can cause problems, I forget the details.

Remember, I'm talking about the potential for errors. Of course everyone says I wouldn't do that, but that's the point it's a goof-up and those things happen to humans. I'd rather complete the process before moving to another train of thought.

After draining, it was learned that the new oil + filter was still in the store.
The car was closed up and rolled to the side because someone needed the ramps.
Later, someone else goes to move the car.

I'd leave a note taped to the steering wheel. However, I see your point. Things can get out of control when multiple people are involved.
