I'm hoping someone familiar with these engines reads this. After a year or so of chasing down leaks - installing a new CCV and associated lines, installing a new VANOS line, installing a new oil filter housing gasket... there is zero loss of oil externally (ie nothing on the floor or anywhere on the engine that I can see). I am still having to add some oil, probably 1/2 qt. every 700-800 miles. I have used 5w30 synthetic mostly (Mobil or Castrol). I read on one of the BMW forums that these engines do have some record of burning oil, and that switching to a -40 might help. Does anyone have any thoughts they'd like to share?
 
How many miles on the clock, because if you are past 100K then most folks would think about moving up to an X/40? Are you still burning oil, because if you are then think about using an approved piston soak and switching to a 10w40 High Mileage oil with a short first OCI? The rings are probably not going to benefit from a direct application cleaner or soak if you do mostly highway miles, but if you get stuck in traffic or short trip a lot an annual clean up can help to clear out the carbon.
 
I would definitely give Mobil 1 10w-40 High Mileage a try or 0w-40 if you would like a slightly thinner option.
 
That level of oil consumption is a bit excessive, and I doubt a change in brand or grade will affect it. My son's X3 2.5 uses less than 1/2 quart of Rotella T6 between 10,000 mile changes- and it has 150,000 miles on the clock.
 
SteveP:

Mobil doesn't make a readily-available 5w30 that is of the appropriate weight for your engine. You need to be using an LL-01 oil, as called for very specifically in your owners manual. If you are just using off-the-shelf Mobil 1 5w30 and Castrol 5w30, you are running an oil that is thinner than what is specified by the manufacturer, which denotes an HTHS of >3.5cP.

You should be using GC 0w-30, Mobil 1 0w-40, Pennzoil Ultra Euro 5w40....etc, any of the LL-01 oils.

Also, what kind of interval are you running with regards to oil changes?

not to sound like a total [censored] but how are you reading on the bmws fourm's and not know the proper fluid to use? 5w30 m1 or castrol is to thin and the wrong oil to use in your car thats maybe a reason why your burning oil.if you "read the Oil Thread's" you need to be using BMW LL01 apporoved oil. one of the main reasons it leak's is the rear main seal a very common issue on bmw.
that being said. you should also buy a new power steering reservoir and hose's they are notorious for leak's. have you also checked your valve cover gasket it also a very common leak there to.

+1. This is a MAJOR consideration.
 
Thank you for the verbal admonishment, which I wholly deserve. I must apologize; I wrote before I checked with my shop and they are using LL01 oils in the car (I change my truck oil which uses Mobil 1 5W30 sometimes). And yes I have been guilty of slipping some of that in the BMW now and then. I do a lot of the mx on the car, but don't do the oil changes typically.

So, I presume I should add some thicker oil now, then maybe look at other options come next oil change, which is only a short time away?
 
Having owned 3-series for the last 15 years, I'm not completely convinced that the car is going to die if it doesn't have LL-01 in the engine. Would I run a non-LL-01 according to the SI? No. Would I run a non-LL-01 oil for extended periods of 100+ mph driving? Again, no.

But for the low-stress driving that most do, and given that we tend to change the oil far more often than it was designed for, I wouldn't sweat it that much.
 
The car has 136K on it. 90% city driving, 22 miles daily roundtrip to/from work for my wife. Tailpipe is sooty, but no moreso than my truck.

I also have had the valve cover gasket replaced.

90% city use is not good for many of the German cars, so keep the OCI short and use an oil that cleans well, like an HM 5w40, as your oil consumption is high.
If you have not cleaned out the cylinders of carbon then it's worth doing with a piston soak or direct spray in cylinder cleaner. Ask on the BMW forum or at a dealer which one is best.
Once you get the engine and cylinders clean make sure you do at least one highway session on a Sunday each month for a few hours to clean out the carbon from in city driving and use a major brand fuel additive if you are using cheap fuel.
Hybrid engines are about the only type that don't mind inner city conditions, unless you short trip and let them cool off between stops.
BMW like to sell their own oil, but there is nothing special about their specs, so most major brand 0 or 5w40's are fine, in fact I think they are less fussy than VW TDI's in particular.

HM is just a swell's up seal's I dont think they make any HM Euro spec oil that is LL01 approived.. not that i have seen.... bmw Oil is great Oil even tho its a group III synthetic. I would never use it mine. not because it's hot a good enough I just Like having the 0W for added protection for cold start's.
