M6 Engine oil issue?

[wzj519]

Hi guys,
Just want to ask a question here. Do you guys have any engine oil issue?
Yes, I am pretty satisfy with my 650GC, it is luxury fast and provide me tractions no matter winter or summer because it is Xdrive. However, I just can't get pass on the engine oil top off issue. Whenever I am driving it, I am afraid of the engine oil warning will on. Just passed 6300kms but I have already had 3 times low engine oil warnings.
I know I am not driving a M car, so I rarely push it hard, even never done a full throttle,but it is just burning engine oil like drinking water. Even my dealer give me free engine oil top off always, but it just lets me feel annoying.
I hate to drive it to dealer always, and tell service guy " come on man, I ran out of my engine oil."
Maybe, this gonna be the best reason for myself to switch to M6 GC, if you guys don't experience the same thing.

It all depend. I have 7000 miles on mine and have only had to put one quart in and I drive pretty spirited. Some members do it more or less than others. Yours sounds like a lot.

4K miles so far, zero quarts added.

Yes, it sounds a lot, but my dealer told me wait for a while. It is possible that gonna be burn less. However, I checked the 6post. most folks have the 650GC N63tu enigine have reported the same issue.

Hopefully, you will be ok always. The first 4000kms I am pretty happy and thought I do not have the issue, but after that everythig started in 2300kms three times.
Do I get a heavy foot suddenly? No.

I've always been told that during the break-in period, don't baby the car. If the limit is say 5,500 rpm, by all means take it up to 5,500 but don't keep it there. Let loose to the limit, then take your foot off of the pedal, vary the rpm's constantly within the limit.

I drove a 550 as a DD prior, did the same, averaged about 1 quart every 9-12K miles, with most of the time not having to top off because of oil changes.

Yes, I admit I baby it during the break-in period never exceeded 3000 rpm.
Will this be the reason it is burning oil?

I love my car just want everything will be okay as dealer told me.
However, since the launch of the 6gc, my dealer just sold 3 (include mine) till now ?
Just can not believe them.

I have no idea, all I know is that I've followed that advice for over 30 years without any problems.

I'm sure there are many here more knowledgeable than I, perhaps they can chime in.

Yes, you babied it too much and never set your rings properly . So now you have significant blowby .
Nothing you can do now though what's done is done . The engine will make a little less power ~2-5% , and consume oil but it's longevity will not be affected . Just add oil as needed and enjoy . Just remember next time to break it in right !

I would agree with that, but aren't the engines ran hard on an engine dyno at the factory? I would imagine the rings are already set long before the customer ever gets the car. Watching those Ultimate Factory episodes they manufacturers running the engine at redline on a dyno until the headers start to glow.

I expect it every 3500-4000 miles.

BMW does not dyno break in their motors . They do dyno test selected motors to ensure they make the claimed hp.

2,200 miles, had oil scheduled M change at 1,200 miles, no oil added since.

When I picked up the car at delivery, the delivery guy even told me do not exceed 2500rpm during break-in. I thought it was too low, checked owner manual which says 4500rpm. Therefore, I did 3000 thought 4500 is limit during break-in. Maybe it is my bad.

Yes. I have done some research
It seems like there is no issue for m6 engine oil. There was the problem for the very first M5 production.

OP, car is still too new. After about 10,000km, you are probably looking at (average) 1 litre / 5000km as normal.

My M is burning 1 litre / 1000km druing break in ... now it varies ... 1 litre / 1000km to 1 litre / 1600km, depends on how aggressive I drive.

If the rings are not set properly in the first 20-100 miles that's it , no amount of mileage will fix it later . Cylinder walls are not perfectly smooth , they have microscopic patterns in them designed to hold oil . These pattens when a car is broken in properly wear evenly and push against the piston ring forming a "seal" during the combustion cycle . If this doesn't occur in those first few miles ( by a proper break in) the pattern will wear and this process can not occur later bc the patten on the cylinder is already worn down ( usually unevenly ) . Then you get massive oil blowby around the rings especially under hard use in the future . Easy break in = loss of compression /oil consumption for the life of the engine .

Yes I think so. My friend has the c63 also told me the same thing. He drives the car really hard and it burned oil a lot during the first 10000kms. However, after that, there is no oil issue.

Technically, it sounds correct. Easy break in will cause the high oil consumption. However, based on the real world information from my friends who drive high performance cars, the first 10000kms they experienced more or less unusual oil consumption. After the period, most of them had a better oil consumption.
Thanks again for reply. Just hope my engine oil will burn less than before.

I have around 5k miles on mine, and have had to add a quart 3 times so far. I drove it fast and hard since I got it with no regard to break in, patience is not a virtue of mine

Damn delano, 3 quarts in 5k... Beast Mode lol

I assume you have no regard to waiting until the engine is at full operating temp either . Lol
