Oil consumption in a 3.0...

[lo_jack]

I was amazed by this myself, as I unfortunately put a lot of highway on my manual 5 speed car. It sucks down oil like a college kid on Redbull at finals time...but it is within spec. I do so much highway I carry a spare case of 5w30 in the trunk because of this.

Anyone had the check oil level indicator get stuck? After I had added the oil the ODB continues to alert me to the low loil evel condition (after I stop the engine).

You either have a failed sensor or you need to add more oil. Either way, the dipstick will be the ultimate decider. If the dipstick says the crankcase is full, the sensor is busted. If the dipstick reads low, the low oil indicator is in fact correct.

My 2001 3.0 also is an oil guzzler. Comes with the territory I guess

Just got back from having my 2005 X5 3.0 serviced, 44K miles. I had added 5 quarts over the last 15K miles and questioned the dealer. I was told that 1 quart per 1000 miles was BMW's low service limit, was shocked as my 323I with over 100K has never needed a drop of oil between 15K services...
By reading this I guess this is the norm, just seems odd. Am I alone thinking this?

Old thread from 2006 but I thought it is important to compare oil consumption.

- 2006 X5 3.0i 5sp MT with 114K miles. I currently add about 1 qt every 1,500 miles.
- Probably "normal" from what I read.

PS: I am familiar with BMW CCV issue (did the CCV in my 1998 528i a while back).
For this E53 vehicle, CCV is still original, but I inspected it: no broken vacuum hoses. Dipstick balloon test shows nice suction, i.e., no excessive crankcase pressure.

I did an oil change 2500 miles ago (when I bought the X5), and haven't lost a drop on the dipstick. 03 3.0 5spd. Just shy of 160k miles.

Even if the CCV looks normal cn90 I'd replace at that age. I replaced my 10 yr old CCV and dipstick guide tube this year (to cold weather parts) and haven't consumed any oil to date. Even if it's looking functional I think due to age there can be some buildup causing oil consumption.

- I don't mind doing the CCV overhaul, but I hate to spend 6h doing the CCV overhaul just to be back to square one!

- So far my inspection shows CCV-system hoses to be intact, no vacuum leak. Suction with dipstick is good with the balloon test.

- For those who have done the CCV, does your oil consumption go down?

FWIW, I test drove a few before I bought mine. One of the service records for an 06 4.4 was for a report of "excessive oil consumption" by the owner. In the report they dealer wrote something to the effect that "acceptable consumption was 0.8L/1,000km". And yet I still bought one.....
