Oil consumption

[beemarman]

Hi guys,

I know these cars drink oil like it's going out of fashion, but I wondered if mine has a serious drinking problem.

Bought the car at 32k miles, now 15 months, and 7k miles later, it has drunk 7 ltr of oil.

That's about 800 or so miles for every liter of oil. Is this normal?

[beemarman]

Just did a search and it seems to be a normal behavior on these cars.

I asked BMW on this and less than 750miles per 1l is considered unusual.

Actually by your numbers it's 1L per 1K miles, not 800 miles. Very normal.

Take it to the dealer for a top ups, they are required to under the SB. Walmart also has the oil for cheap. By the gallon.

Same experience. Mine has consumed 3 liters in 2000 miles and dealer said it's normal and to be expected. I'll deal with it.

Did you try opening up your airboxes to check for excessive oil blowby? You might need your pcv valve replaced.

Dealer told me the same thing, drinks oil, and to drive the car hard as its designed for. But I dont have excessive oil consumption though.

Post-seating and break in, I don't see how any reputable OEM would consider 1L/800-1k miles as 'normal'. The turbos or heat in general is cooking this stuff off along with some blow by (soot on my exhaust tips).

That shis be all kinda forked up.

High performance, high compression engines do that. Toyota Camry engines don't, for the sake of comparison.

My M6 CP has required no top ups in 22,000 miles including track days , in fact my oil gauge has never gone down from full ( oil changes at 7500 miles) . It's all about seating the piston rings properly in the first 100 miles when the car is up to temp then varying rpm and gears for the first 1000 . If you drive like Mrs daisy , or redline it when cold then you get blow by for the rest of the cars life .

I'm glad you posted this because mine also has required no top ups in the 2500miles I've driven it (2014 CP, bought it with 9900miles as CPO) and I was beginning to worry that something was wrong with my oil sensor since it still registers full when I force a check and there are so many people talking about their cars using oil.

My E60 M5 used oil, but still only about 1qt every 5000 miles or so.

I have 45k miles on mine. It is getting to be pretty annoying going through a quart every 800-1000 miles. Had 5 AMG's previously not a one consumed oil. Mine is a 2013, maybe it was worse in the earlier years.

Mine is in the shop for Oil Consumption Analysis. 4qt of oil within 1k miles, that's 250 miles per qt. Pretty much the same mileage as a modern Diesel engine.

I doubt it will pass the test. I don't want a new engine, but most likely going back to an F80 M3. The S55 doesn't drink oil and has better mpg.

Thats disappointing especially given all of your modifications. Keep us posted on the outcome. What is your mileage? I am at 3500.

Ouch....that is the most I have heard of to date...

I'm at 20k miles. Apparently the BMW Service Bulletin says 2.5 qt per 1k miles is normal for normal driving. More than that is normal for aggressive driving. I've been driving the car normally.

I bought the car used at 19k miles. The first owner didn't break-in correctly. Note to self, never buy a used M car again.

Some say beat it during break in, some say take it easy.. who the hell really knows.

Buy a new M car and watch it plummet in value. Buy a used car and have to top up oil as the manual states. Oil consumption is so normal and it's documented, not just on BMWs, but other high performance cars like my last Porsche I bought brand new. I broke it in as the manual dictated and it still consumed some oil.

Enjoy the car and stock up on some Mobil1 from Walmart.

Topping up oil like some of these members are stating is unacceptable. Bottom line. My 6.3 AMG burns 0 oil never a top up in 8k miles. Bought it with 21k.

Besides this whole burning oil thing seems to be more common on the 13 m5's.

Actually there's only one member in this thread who states unacceptable consumption. The rest are in line with what's documented.

Been lucky with my '13. Bought it this year with 18950 miles. So far so good.

When you have to add 1L during every other fuel fill up, you have a poorly designed engine, a leak, poor oil or any combination of these. Seems like a lot of conjecture on break-in methods and model years. Bottom-line, like the N63 drivetrain malfunction debacle, looks like the S63tu also has some issues.

I am at 1L/850 miles with 3500 on the odo so i will wait until 7500 miles to determine if my motor has settled down on oil usage before drawing final conclusions on my own power plant.
