wrench size of oil drain plug

Getting ready to change oil and filter in my 2008 328i sedan.

What wrench size is the oil drain plug?

Since this is the first time I am changing the oil, I'm figuring dealer may have over tightened and I may possibly need to use a breaker bar.

Yessir! Doin' it right:

Wrench size

Oil drain plug [oil pan]........Bentley doesn't say!
Oil filter housing..............Use oil filter wrench


Torque

Oil drain plug [oil pan]........25 Nm 18 ft lb
Oil filter housing..............25 Nm 18 ft lb


Screwed again, eh. Certain to be metric, don't you have a metric socket set? Get one if y'don't!

17mm comes to mind. If nothing else, it's the first one I reach for when I change my oil. Now, if I could just remember if end up I reaching for a second one.

I can't believe you would need a breaker bar. Even after a dealer change, I've never had it be more than a relaxed one hand pull to start it moving.

First change for you? Make sure you find and remove the existing copper crush washer. The factory-installed one on my car was so hard up against the plug, I didn't see it until I started prying with my fingernail.


EDIT: Yup, 17mm. Just went down the cellar and looked at my socket set. The 17mm has the little drops of motor oil inside the socket in the back corners.

Slide a pipe over your ratchet if you need more torque and post back here what size you find it is, my first oil change is coming up in 1K miles and I want to know also.

You won't need a breaker bar, 18 ft lb isn't that much at all.

I recently did my first change, and since then I often repeat a couple of tips.

If say your 17mm socket is 1/2" drive, and your torque wrench us 3/8" (which it probably will be), do not use an adapter between them, or the head just won't fit right, and you won't be able to torque it down properly. Ask me how I know.

Also, for how cheap they are, I think getting some of those "hook picks" are well worth the couple dollars, it makes removing the smaller green o-ring from the filter housing so much easier than with any other tools I had. I don't have to worry about scratching the filter housing anymore.

If you've never had a car sit as low as this BMW before and are using ramps, you will likely need wood planks in front of the ramps. I put the ramps on cheap mat/carpets I picked up from Costco to prevent sliding. Don't forget to chock, parking brake, etc, I know you know all that, just for good measure.

Re: wrench size of oil drain plug

Just changed my wifes e54 last night and I used the pump. Boy that was convenient! No need to jack it up, oil pan, and going underneath to screw unscrew. Simply pump akd sucks it all up. (Patiently waiting for the cons on using one)

OK I'll bite. Stuff laying in the bottom of the pan that did not go up the tube?
I usually change with warm just agitated oil.

That's how I've changed the oil on all my cars, if going through the trouble of changing your own oil it's better to do it 100%.

Oldest is a 1990 Accord EX still going strong, change the oil every 3k with regular dino oil.
