True Engine Oil Capacity
- Thread starter free2d

Most of the oil comes out make sure you change your filter if you want to get as much as possible of course.
Most engines leave relatively little oil behind when drained. Automatic transmissions on the other hand only have part of their fluid in the pan. Most of the rest is inside the torque converter which typically holds half or more of the fluid.
My car's factory service manual mentions engine overhaul oil capacity and oil change amount with and without oil filter (5.15, 4.9 and 4.5 quarts respectively). I usually get 4.5 quarts out.
Yeah. The manufacturers take that into account when recommending oil change intervals.
...unless you happen to have an RX8. Almost half of their oil stays in the coolers.

Their might be. The best way to get it all out is to let it warm up before draining so it flows quicker that’s usually what I do.
The owners manual for my '16 Versa gives 3 7/8 qts. (3.875) capacity for oil/filter changes and 3 3/8 qts. (3.375) capacity with a filter change. When I change the oil/filter in it I put in 3.2 qts. and it always reads just slightly over the full mark but not enough to hurt anything. 3.2 quarts is within 1 oz. of being 3 liters and I thought maybe 3 liters was actually the correct fill since the manufacturer is in a country that uses the metric system. I always change the filter when I change the oil so I don't know how much it would hold without a filter change. As small as the filter is I don't think it's possible it could hold more than 8 oz. If I was doing a change without doing the filter I'd probably put 3 qts. in it and call it good.

Depends on the filter used. Oversize the filter, more oil in the engine...
My Smart says 3.7, but with the oversized 51356 filter, I put in 4 exactly...
If you have a Kubota HH164-32430,
take a look at Wix 51773, the two quart version...

OCD people say a lot of things that aren't always of any benefit unfortunately. Get the engine warm, pull the drain plug and let the oil drain, 30 minutes works well for me, if you're OCD let it drain longer. Think of how many oil changes a quick lube place like Jiffy Lube does a year. Trust me they aren't letting the oil drain for 30 minutes, they'd go broke. While I'm not a fan of Jiffy Lube, the cars serviced there seem to survive. Honestly I'd find something else to worry about.
In terms of pure volumetric measure of what went in versus what went out ( excluding any losses from leakage/consumption/evaporation etc.)
Yes, there will be some trapped and clinging residue remaining ( just like in the bottle from whence the oil was poured in from)
There will be some variance between various engine designs and conditions ( assuming all drains were done level to Earth and for the same time at temp)
Now, is that itsy bitsy teeny weenie yellow polka dot amount going to matter in any significant manner?
Only maybe once in a zillion.
Who has said you shouldn’t mix certain brands or viscosities?
No, More like 5% if you drain pan and filter
I always struggled with this. Seems the longer you let the vehicle sit, the oil would have longer to make its way to the pan. But a warm engine would definitely drain faster. Perhaps it may make the filter a little easier to remove to if warm.

I’ve also seen people bump the engine to get it to get as much out as it can though I don’t recommend that. And yeah I usually use the warm engine method when it’s colder since the oil will flow better when it’s warm.

I use the Fumoto valve on my cars. I simply drain it pretty hot and give it lot's of time. It's very convenient and a little slower, but I like it this way.
