How many miles to a litre of oil???
My car is a 2012 F13 with 14k miles on the clock.....and is requiring a litre of Engine oil every 800 miles. There does not appear to be an oil leak.
I drive the car sensibly but enjoyably. How often do you need to top up with a litre of engine oil driving 400 miles per month. Any usage information and advic s would be an indicator of what I should expect. Cheers everyone. Pinky |

I have just under 4k miles and have had to top off with two quarts every 800 miles or so. My 650i did the same thing but at a longer interval. The usage does improve as more miles are put on the engine.
Also, if the car is asking for 1 liter/quart, go ahead and put in 2. This was the advice of my service advisor. I would consider this level of oil usage normal. |

I know Oil Weight was mentioned, but the "allowance" last year was 1 Lt/ 1000 miles, anything under that was unacceptable and work was needed under warantee. A couple of M5's were returned to a dealer here to my knowledge for high Oil usage, and were refunded their money after a long drawn out process. BMW have since that time introduced this test and some form of remedy.

I agree that just because these are high output motors they don't necessarily need to burn oil. Take it easy on your engine and you'll see less consumption - no hard running until hot, a little idle before shut down, and I like to change mine more frequently than the recommended interval. Works for me. |

My M6 GC CP is like Johns, I've added 250ml (1/4/ Quart) over 24,000 miles.
Factory spec is 1L (1Quart) per 1,000 miles. If you are using more than that and are under warranty then they should fix it, whatever it takes. As has been said a lot on this and other forums, oil use is very closely related to how the engine is run for the first 100 miles or so. An engine that is run at close to the max allowed revs in the 1200 mile running in period, without asking for a lot of power, and which has had plenty of engine breaking from those revs will use less oil and produce more power than one that has been babied. However, having said that, 1L per 800 miles is not acceptable and not normal. |

Cheers Richard
Have booked car in to BMW Workshop and the responses I've received from Forum posters confirm that my current usage is an issue that needs to be fixed under Warranty. Thanks for your advices. Pinky |

For the first 100 miles only, low RPM high gear cruising is bad. After 100 miles, high gear low RPM is good (so long as you are not lugging).
High power initially is good for piston ring beading, but to offset that bad for bearing wear, so you need to hit a good compromise. As ring beading stops when the bores get coated in varnish from the combustion process, early beading in is essential. Wear on the bearings continues for much longer, so after the initial period you should be more gentle. http://www.mototuneusa.com/break_in_secrets.htm |

On our shop's F06 M6 with 20,000 miles now I have only added engine oil about 2-3 times max.
Some experience more then others. But if its under warranty make sure to go to a dealership so they can make a note of each visit incase the consumption gets worse |

You can also visit the dealership and ask them to add it up.

"The company said some regular BMW motors can consume up to a quart every 750 miles, and M series performance engines can use up to 2.5 quarts per 1,000 miles under certain conditions. The company says it has a service campaign to check and possibly replace some parts in the 4.4 liter V8."
