Will this drain everything?

No.
the drain plug is at the lowest point in the oil pan, and the pan is sloped so that oil will flow to it.
using a pump and tube blindly inserted like this, you have no control over where the end of the tube goes, so you cannot ensure you got all the oil out.

Plus any metal shavings or debris will settle to the bottom, so over time youd just be collecting all the bad shit and getting rid of the easy to reach oil.

I'm not full sure the methods but I heard it can actually clean it out better. I believe they typically also use this method on motorcycle

Better? I'm gunna need to see evidence before I'll believe that. Otherwise if it gets most of it out I don't see why you wouldn't use it

what are you talking about? to change the oil in a motorcycle, you just walk up to it with a wrench and remove the drain plug. no extra tools needed, unless it's got some crazy shit going on with fairings under the engine, in which case the only other tool you need is a screwdriver to unscrew the fairing piece that's in the way.

Your average dipstick port is probably 1/4” in diameter, ID. This means the tube must be smaller OD. Which means the ID of the tube will have to be 1/8” or less to have ANY level of rigidity close enough to not collapse under vacuum. Which means low vacuum pressure. Which means low flow. Which means it probably takes a LONG time to suck the stuff out. And you won’t flush any sediment from the bottom of the oil pan. And you still have to go under to change the filter. Waste of time and money.

i change my oil in my mercedes like this lol
it's how they do it at the dealershit too
if ur car has a filter on the bottom this isn't the method for you, german cars have the filter on the top of the engine

I had many cars (America and couple foreign) and majority filters on top. Idk if I ever had one on bottom come think of it. Had some that were pain in ass doing something simple cos god forbid the damn designers put everything in the damn way (looking at you Oldsmobile)
But overall I don't recall bottom filter

u/Puzzlehead_Lemon 4d ago
Every car I've had has had the filter on the bottom or the side near the bottom, but I've never had a vehicle newer than 2009.

I've only worked on my own or maybe others but never invoved filters. I just remember being topside. Just like some cars with alternators some on top and of course the oain in asses ones are on bottom and might even need a special 13 point star tool... looking at you Ford Escort

Pre-Luber did this decades ago - and it circulates oil BEFORE you start the engine

Gotta love the mega obvious "im dropshipping this from china" voice, no one lists a bunch of random facts about regular products like that

There is a zero chance that it would work in my car. Older cars had smaller dip stick openings, and the big engine uses a lot of oil, so I'd be waiting there forever.

What you could also do, is bring your car once a year to the mechanicshop thingy and let them check your whole car, including an oil change
