Article in the August issue titled Oil Crisis lists the worst cars for burning oil as reported in their Annual Surveys. Top of the list, BMW 5, then BMW 7, BMW 6; table covers 2010 thru 2014, and % of cars reported that used a quart or more between oil changes. Subarus also mentioned, along with Audi. Some percentages as high as 61. Too much to summarize but I don't ever remember seeing this much info about oil burning engines.
Recent article in Road & Track (several months back?) told about BMW having trouble with an engine burning oil and also batteries not lasting, and their solution was to replace batteries at 10,000 miles under warranty. Seems that the engines ran hot and the cooling fan would run after engine shutdown and wear down the battery. Changing software would lower fuel economy and subject them to class action lawsuits, so they replace battery!!!!
