Am I the only one who adds a quart of oil every 1,000 miles after 3,000 of oil change? (I usually change oil @ 7k miles) Mobil 5W-30 (odometer 80k miles)

I use CHF 11S (06 530xi) for power steering

BMW I6 motors are known to consume a bit of oil- All of mine have in the past. My V8 uses zero oil. It seems a little high for you, though- I would point you in the direction of the CCV (possibly ripped diaphragm), and anything else connected with crankcase ventilation. Also, as simple as it sounds, check underneath for leaks- You'll need to take the front protective pan off.

I'll check this thread, rather common on BMW with ext-oil change to have CCV valve clogged or busted. One of the symptoms is "excessive oil consumption"...

Or worst you have compression problem on one of the cylinder, that's engine overhaul time and $$$

Are you asking or stating? The easiest is to check what the reservoir says for PS.

My '06 530i (I6, N52 engine) with 115K miles doesn't consume any oil between 7K oil changes.


Qt for every 1000 miles is not normal...

Is there any way without having it checked by mechanic if there's really a compression problem ? or how can CCV can be checked ?


I heard a lot that BMWs use a lot of oil

Last time I asked my SA, he said nothing will be done unless consumption gets to 1qt in 750 miles. That's a lot of oil!

My 2006 530xi goes through about 1qt in 4000 miles.

The N52 is good for failing oil filter housing gaskets AND oil cooler gaskets (in which the N52 for the 330i are a different setup) which contribute to excessive oil loss. Im not sure about oil burning or consumption. 110,000 miles for mine and its been good on the "consumption" since 107,000 miles when i changed my housing, oil cooler, and valve cover gasket.

How much did it cost ya to change all that stuff? Was there smth wrong or u decided to change those just in case?

I will keep this in mind for mine as I go. Have almost 100000 miles now.

I was thinking mine might be the valve cover gasket. My X3 is the same.

See post #12 on this thread http://www.bimmerfest.com/forums/sho...d.php?t=534005
for testing CCV yourself.

Compression test has to be done with tool and best to leave it to a mechanic, I heard someone paid $100 for the test, not bad ; but do it after you are sure your CCV is not busted.

As far as valve-cover leaks, I never seen a really bad one that you need to top the oil every 1k-miles, I had a bad VC gasket leak on my V8 and it foul the plug first and never seen a drop of oil even on the bottom cover (let alone on your garage floor).

Only the cost of parts which was just over $200 I think. I did it all myself, but I also did the belt hoses spark plugs and the infamous valvetronic motor gasket (which I don't recommend anyone doing themselves if not ready to cough up thousands if you screw it up). I did a few coast to coast trips the past 3 years so 100k snuck up pretty fast. It's best to catch everything around the 70k mark though.
