Good to the last drop
 

I thought I would try this experiment.
I had the engine up to temperature and decided to drain the oil.
I pulled the plug and out it flowed.
I waited for about 15 minutes to let it drip slowly.

I then pulled the big drain pan out of the way and used a 16oz plastic cup.
I let the X5 drip all night.

I think I might have gotten 1 to 2 ounces more oil out.
Had the experiment gotten 6 to 12 ounces more oil, I might
Do this every oil change.

So, my experiment showed that 12 hour overnight doesn't result in
very much more oil drained.

Good to know - you just saved us all half a day! :thumbup:

Good to know...I will feel less guilty about a quick oil change now. :D

If you have an air compressor, you can speed things up a bit by sticking the air hose in the oil fill hole and sealing it up with a shop rag.

Maybe keep a big piece of cardboard underneath as there might be a bit of splatter.

Flush it with new oil at the end
 

Other approaches
Add a 1/2 Litre/Qt after the dripping slows down to flush the remains out. Wait 5 mins and put the drain plug back in. Clean now.:D

This is similar to what I do.

I hot drain the oil for around 10 mins, add a clean Qt of oil (to "push" the used oil out of the pan), then let it sit overnight.

Dealer sourced filters ONLY!

TiAg, why dealer sourced only?

I've used Mahle and Knecht with no problems?

Dealer sourced filter is more important with spin-ons. You guys are making way to big a deal of draining your oil! I am pretty high on the OCD scale but even I don'y worry about draining every drop.

On the diesel, MANN are the manufacturers of the OEM part for BMW so I only use MANN, some tell me Crossfield are just as good but I will only buy MANN. I would not go to a stealer in the UK as they are ridiculous on price and sadly there is not a decent BMW dealer for miles. Shocking really as I live in a part of London where everyone has a BMW.

MANN is an excellent filter for the BMWs

All OEM filters are not created equal.

I get my filters from the BMW dealer to ensure the OEM manufacturer has produced the filter to BMWs design/materials/processes/tolerances, in an ISO certified facility.

Filters produced by the OEM manufacturer for "open market" distribution (non-dealer network) have no oversite by BMW, this allows for filters produced in non-ISO locations, and with no requirement to follow the BMW design/materials/processes/tolerances (OEM manufacturer is free to "cost cut" the filter production as they see fit).

And there are full blow counterfeit filters on the open market too......

TiAgX5 is right. Mann filter for my m54 doesn't look so great, not much for gasket material on the ends and pleats can't take the pressure of the spring and get creased after a while creating the potential for a tear. I ordered a Bosch filter and it looks to be of much better quality and only a buck or 2 more.

I also agree with TiAg - for the $10 a filter costs I buy from the dealer

The topic is just.
Be this poem or lyrics?
Findings are useful.

(hope you liked my Haiku response - BTW put this post to a beat and you'll sell records.)

And a little more on-topic. I did an oil change the other day, and had both a Mann and Mahle (neither bought at the dealer) side by side for comparison, deciding which to put in. They both looked high quality, obviously fit well, etc., but the designs between the two are VERY different. Interesting. I don't doubt that either one will do its job well. I put the Mann one in, for no particular reason.

And also, for those who are concerned with every last drop, of course when you remove the oil filter cap all the oil trapped in the filter canister will drain out. So don't wait for every drop to come out of the drain plug before you at least loosen the canister cap.

:iagree:Loosening the oil filter cap is a must for a proper oil drain and service.

Not us 4.8is owners. All oil change work is done under the car. One wrench to the oil drain plug, then the filter, which is hanging upside down on the the bottom of the engine block. We only have to open a little plug some engineer decided we needed and put it on the bottom of the oil filter housing to drain everything inside the filter. (#5 on the image below)

You are jumping through hoops to get the last tablespoon or two from 8 quarts of oil that the crankcase holds? You are chasing the last ounce of 256 ounces. You're after less than one half of one percent of the oil. Hardly a worthwhile endeavor. 1 / 256 = 0.0039, or 0.39%.

Drain the oil until it stops and move on.

Isn't that exactly what the OP said? :D :thumbup:

Yes, that's what he said after he jumped through the hoops.

I ran the numbers through a calculator in less time than he took to describe the 12 hours of waiting that he went through.

The fresh qt dumped into the engine (1/2 in the oil fill, 1/2 in the filter canister) removes the most of the old standing oil that usually remains in pan.

May not be doing much good, but I always do it.

Yes very true for the N62 equipped X5s

That's the filter on the bottom?

All these years, and I never knew that.

Go figure
