645 Oil Change DIY

Can anyone specify the proper oil change procedures for an 04 645ci

1) Oil Amount, Type/Brand oils people use
2) Oil filters people use
3) How to reset the oil life indicator
4) Any Special tips or thing to do

I always change my own oil, just like to make sure it is done correctly. This is my first 6 Series and just wondered if anything special needs to happen or any secrets.

Thanks

I don't think anyone on this forum changes their own oil as that question never gets answered. I've also always done my own oil changes but it looks like I'll have to use the dealer or some other place for the 650.

Yes....I would tend to agree......I think most of us would call our BMW dealer for an appointment.

I've changed the oil in my 645 once at this point - there's no magic to it, but it's a little different than non-BMWs in a couple of respects. With regard to your specific questions:

1) It holds 8.5 quarts - make sure you have a drain pan that holds at least that amount (most don't). I used the OEM oil ($8 per quart from BavAuto), but I believe any 5W-30 synthetic would do.
2) Like most BMWs, the 6 uses an internal oil filter (no case), and I don't think any of the usual aftermarket sources (Fram etc.) offer replacements. Again, I stuck with OEM from BavAuto - I forget the price, but next to the cost of the oil, it's trivial. It also includes fresh gaskets for the drain bolt and filter cover.
3) My understanding (and this may be flawed) is that the cars electronics monitor the oil life directly, so for oil changes, no reset is required. My plan is to change the oil every 7500 miles, so I didn't bother with a reset.
4) There's a trap door in the plastic belly pan under the car. Open it and you have access to the drain plug and the oil filter cover. The OEM service manual indicates an 8mm hex wrench for the drain plug, but I found a Torx bit (T45 or T50, I forget which) was a better fit. You'll need a large socket (24mm I think) to undo the oil filter cover. Apart from that, the usual advice applies - make sure you've got a good set of ramps, some rags, etc.

There is a good post (with pictures) on one of the 5 series forums regarding oil changes that applies pretty much step-for-step to the 6, but what I've said above should cover most of what you need.

Hi All,
Is there anyway I can fill up the oil? I mean that if the oil level too low. Could I fill it up a little bit, or i have to bring it to the dealer?
Anyone know how? please help.

Hello,

I try to explane how to reset the Idrive, bud English is not my language so its a little dificult...

Put contact on
Push A button on the dashboard (A= left button on the I think you call it odd meter? where you set back the day millage?)
Hold this A button for at least 5 sec.
Then you see the menu on the milage meter.. With all the service stuff...
If you have found the service oil menu, press again 5 sec the A button... and its reset.

I make pictures later...

Hello,

I opend a new tread for you and other 6 drivers how to reset it easely.

On my 630i I needed 6.5 liters oil. I did not use the 5W40 oil, I only use 10W40 oil because it makes less dirt in the engine. Bud I change it every 10.000 km, and not 25.000km like on the manual.

Oil filter I buy after market for $13.

The amount of oil is in your drivers manual!!

Also hands on guy

Thanks everyone for this thread, I am a first time BMW owner and also like to do my own maintenance.
Your posts are going to make my first oil change easier, although I guess my biggest concern is getting the car on my ramps, with the low profile I think I may have a problem.
Thanks

Take a look at my oil DIY. I have pics in there on how to get your car up on standard ramps using 2x10 boards in front of the ramps. It works like a charm.

Another alternative is to buy Rhino Ramps which are designed for lowered cars.

Bmw oil banter! Solved, period!

Actually that is not quite correct about "Castrol Syntec suggestion"!

Castrol Syntec. Is a TOTALLY different formulated Engine oil and should NOT be used on all BMWs... It is not the "Universal" Engine oil for BMW's.

BMW has had a long standing performance and oil developing relationship with Castrol since 1999. BMW has partnered with Castrol for developing the Correct OIL's and lubricants for EACH and every Engine that BMW has built (Different Engines have different performance based requirements) And Castrol is the ONLY oil used to this very day!

For our 6 Series BMW's you should NOT USE SYNTEC. Different formula.

What should be used is Castrol EDGE. PERIOD!

Below is Directly from Castrol's Performance Website under the Partnership section and Oil selection area! Simply find your BMW. BECAUSE remember different Years have different Engine No. like N62 for example. Please use this data for your BMW's Engine Oil IF you do not want to use BMW Branded Motor oil, which CASTROL does supply BMW with.

Cheers!
