The goal of the poll is the find out if there is a correlation between proper breakin and burning oil. The two choices above are all that are needed to see that and make the results less confusing.

If choice 1 wins with some significant numbers than there is a correlation. If it's a tie there's no correlation. If choice 2 wins then not following the breakin will get you better oil burning characteristics.

In my view, driving the car hard under any break-in conditions will tend to lead to higher oil consumption. People who are inclined to violate the break-in procedure are also more likely to drive the car all the time. I guess I think there's other variables involved that we aren't accounting for in this poll.
lol, beat me to it

I'd say the two major factors that contribute to oil burning are lugging it a lot especially during break in and treating it rough when it's cold. Both of these shave metal.

Opinion. My car is new and has only 200 miles on it. By the time my car hits 1500 miles on it , it may take close to a year. So I have been conscious to short shift when cold and then gradually rev slowly to around 3.5-4k rpms until proper temp is reached. I wont redline for another 2-300 miles but I believe it is unreasonable for the engineers to build a car and expect users not to explore the potential for 1500 miles and no sport. It is an overly conservative method on the part of German engineers. Opinions?

Call me dense, but with just two choices what are you conclusively proving?

I didn’t follow the break-in procedure and don’t burn oil but I am lumped in with those that did follow the break-in procedure and do burn oil.

You have two different methods of break-in resulting in two different results but lumped in as one conclusion. Would it not be better to pose the poll questions as such?

Broken in per BMW, doesn't burn oil.
Broken in per BMW, does burn oil.
Not broken in per BMW and does burn oil.
Not broken in per BMW and doesn't burn oil.

Like I said, call me dense but I still don’t get it and I thank you all for your explainations.

How many other cars do you know of that require a 1200 mile break in? If the guys building this car say it's necessary, then I'll believe them. These are the same geniuses that built this car. They aren't doing this to frustrate anybody.
Your money, do with it what you will. I tend to listen to the M creator.

The goal is to see if there is a correlation between breakin and oil consumption. Choice A are the two choices that support a correlation between corrent breakin and no oil consumption, choice b supports that not following the breakin means no oil consumption and a tie means they are unrelated. 4 choices would just confuse the results.

Yes, I understand the goal of the poll; to find a correlation between break-in procedure and oil consumption.

In my case I did not follow the recommended break-in procedure (B2-“not broken in per bmw and doesn't burn oil”) but I had the same result on the poll as those in A1 (“Broken in per bmw, doesn't burn oil”), or our cars do not burn oil. Conversely if someone answered B1 (“broken in per bmw, does burn oil”) they would ostensibly have the same result on the poll as A2 (“not broken in per bmw and does burn oil”), or our cars burn oil. What does that prove except that it doesn’t make any difference how you break-in the car, some will burn oil and some will not?

Now I don’t believe that and think that break-in is important and don’t see how this poll, the way it was structured, results in any conclusive cause and effect of break-in procedure. You either followed the recommended procedure and it burns oil or doesn’t or you didn’t follow the recommended procedure and it burns oil or it doesn’t. For this poll to result in any meaningful conclusions it needed four separate choices, not two as there are two procedures (follow the recommended procedure or not) and two results (burns oil or not).

At this time there are 16 that answered A and five that answered B and we don’t know if they answered yes or no to following the recommended procedure OR answered yes or no to burns oil or not. :nixweiss:

by being grouped with the people that broke in per bmw and burn oil, you're in the group showing that the break in procedure does not reduce oil consumption if done correctly. If we made 4 groups we would have to add your group to that group to get meaningful data. It might be more interesting to see exactly what each group has done but it would make the poll more confusing because you would have to add the groups to get useful data.

I see you don't think it's important from your ignoring it. Personally I do, but I have nothing to back that up other than the fact that they made it extra long for our car, which I dont' see why they would do if it was not necessary as it takes away from people's enjoyment of the car. I'm hoping this thread will shed some light onto an actual measurable effect on the car. I'd prefer dyno number's but not that many people have dynoed their cars

Again, four choices are not needed-- the first two are the choices that support the breakin period, the second two support it being the opposite of good. A tie shows it to be irrelevent to oil consumption. Nothing is to be gained by breaking it in to four choices as it doesn't actually matter if you were "broken in per bmw, does burn oil OR not broken in per bmw and doesn't burn oil"-- both show equally that the breakin was not helpful for oil consumption.

You have totally lost me now. Simple question; with 22 people responding to your poll so far, how many burn oil? :nixweiss:
