From consumer Reports: Oil consumption: Not all engines suffer from this problem. In fact, our data shows that owners of 98 percent of 2010 to 2014 cars did not have to add oil between changes. So we were expected to continually check our dipstick on this magical Prius every week while the reservoir ran dry?? I don't think so! Does not pass the reasonable man test. Surely there has to be recourse with Toyota for this oil burn ???
