oily, and I can't get any sense out of the manufacturer.
Our car, a BMW 330i, has always used a lot of oil, as much as 4 litres+
between services and we have always been told it's "within tolerances of
0.7litres in 1,000km" and probably due to the way we drive it !!
Recently we drove to SW France and I filled the oil to Max before leaving
home, after a couple of days down there I checked and as expected it needed
almost a litre of oil to bring it back to Max. Situation normal.
Spent almost another week down there driving around and then back home and
some days later checked the oil and it was still at Max, a week later it was
still at Max. Engine seems to have stopped using oil suddenly.
Any ideas why/how that could happen?
I wondered if this engine has an oil cooler and it's just started working.

Re: OT Car Oil Consumption
<Oil use>
Maybe the rings have finally bedded in? I drive a Volvo B12 coach at
work, and it took over a year for the oil consumption to settle down to
the same as the other one had from new.
I've also noticed a reduction in oil consumption after a long blast when
an engine had been used on local work for a longish period, although
admittedly this was an older engine. In that case, I suspect that the
rings had got gummed up, and cleared with the heat and vibration.
I call the long fast blast in a town-dwelling car an Italian tune-up......

Seeing as I have known this engine and it's high oil consumption for 68,000
miles I always carry 2 litres of oil with me on any trip. It's the oil I've
used for a long while, Castrol Edge Sport 0W - 40 which conforms to BMW
LL-04.
I often accelerate using full welly and am known by friends as being a fast
driver so I can't see the "Italian tune-up" being a possibility. However I
am wondering if the hours spend with cruise set at 130kph (82 mph) may have
cured a problem since new like, perhaps, an oil cooler thermostat suddenly
starting to work or a pipe blockage moving so cooling the oil and stopping
it boiling off.
It's just weird.

Re: OT Car Oil Consumption
But does the engine ever get seriously warm or is all your driving
'round about town'? A quick squirt doesn't get the engine warm.
Oil doesn't 'boil off' but it does burn away if it gets into the
combustion chamber. My suggestion would be that the engine has finally
got properly warm and something like sticking piston rings have freed
off thereby making them work properly and keeping the oil where it
should be.
I don't think that a sudden bedding in would take place with 60000
already on the clock (assuming that the engine also has 60000 on it).
... but you're happy now!

No, I do mixed driving with longer journeys to Cornwall and the Lakes and
France thrown in a few times each year. I think nothing of driving 60 miles
each way for lunch.
Yes, and intrigued, but is it a sign something is going to let go soon.

Re: OT Car Oil Consumption
I doubt it, unless yours has been messed with. 330d, maybe...

Re: OT Car Oil Consumption
Mind, it still shouldn't use oil to any great degree. I've heard this said
about several modern engines, though, that they expect some oil consumption.
The TD5 uses a bit. about 6K since the oil change, I had to put a litre in.

Re: OT Car Oil Consumption
Phew! I've got a 1988 V6 Commodore that I've put 1.3 million km on
without overhaul. Power's way down, but it still only uses 0.5 litres
of oil *or less* per 10,000 km. That's been on LPG since new.
So any idea why modern engines should use such large amounts of oil?.

Re: OT Car Oil Consumption
engine to relieve crank case pressure the proper way and not allowing
oil to go past the rings
i remember when i worked for bmw some of our lads had company rented
cars and couldn't believe the oil consumption after our rover rentals
had never used a drop
i couldn't tell if my disco burns engine oil cause most of it ends up
on the drive
oh my MGZS diesel never uses any oil and thats done 120000+

Re: OT Car Oil Consumption
Km's as Bob was quoted. I asked the question at the garage when it
was first serviced and was told that "....this is normal sir, if it
starts using more, bring it in.". The van gets a hell of a thrashing
round town and up and down motorways. My old one never used a drop
and that had 120,000 on it, but was a 1.7 Tdi lump. The only problem
i've had oil wise was when the nut holding the oil pump pulley on fell
off.....lots of noise and a very lumpy engine. The tightarses at the
lease company wouldn't pay for a full check over and told garage to
replace the pump and "...we'll see what happens...".
