Consumer Reports finds some newer cars burn too much oil
In an annual survey of car owners, significant numbers reported what the magazine considered to be excessive oil consumption.
Consumer Reports focused on 2010 to 2014 models and called on automakers to make repairs under the powertrain warranty or to extend warranties.
The magazine's survey didn't find any link between oil consumption and other engine problems, but it found that cars that burn oil early consume more as they age.
Audi spokesman Bradley Stertz said a class action lawsuit against Audi over oil consumption by the 2.0-Liter turbocharged four-cylinder engines is close to being settled without the company admitting liability or wrongdoing.
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.
