Consumer Reports: Worst cars for guzzling oil | Consumer News | Seattle News, Weather, Sports, Breaking News | KOMO News

(Fortunately, it doesn't appear Nissan is on the list of offenders!).

If your car seems to be burning oil and you have to top off your oil frequently, you have company. Consumer Reports' latest auto survey covering almost 500,000 newer cars has identified several popular engines that burn quite a bit of oil.

Consumer Reports has listed 30 cars with model years 2010 to 2014 as top oil burners. The worst are the BMW 5, 6, and 7 Series and X5; the Porsche Panamera and Cayenne; and the Audi A3, A4, A5, A6, Q5, and S4. You can get the complete list on ConsumerReports.org.

Excessive Oil Consumption Isn't Normal - Consumer Reports

Consumer Reports' auto experts say that it's normal for cars to burn a little bit of oil as they age and get closer to 100,000 miles. But for an almost new car that's still under its warranty, you shouldn't have to be topping off the oil between changes.

Audi, BMW, and Subaru say that oil consumption is a normal part of a car's operation. But Consumer Reports finds that 98 percent of owners of newer cars don't have to add oil between oil changes.

Subaru, Audi and Toyota are subject to class-action suits regarding the problem of oil consumption. And Honda recently issued a warranty extension to cover the problem. For 2008 to 2011 Accords and 2010 to 2011 CR-V four-cylinder engines, the warranty is extended to eight years or 125,000 miles. And Toyota amended its powertrain warranty on its four cylinder 2AZ-FE engines, to 10 years or 150,000 miles.

Consumer Reports believes that any engine that burns oil, if it's still under the manufacturer's powertrain warranty, needs to be repaired or replaced.

If your car requires oil frequently, Consumer Reports recommends you to take your oil receipts to your dealer and ask for a fix.

This is interesting because in the past 2-3 months, the Z has been going through a lot of oil. I first noticed when I was street tuning and the low oil light flashed, checked my oil and it was barely on the dip stick. Topped it off with about 4 quarts. A little over two weeks later, had to do the same. Not sure what the issue is, no leaks, no tears, no tracks.

Consumer reports is right. Beyond break in, there should not be any significant oil consumption (and even then it should be minor) if the rings have sealed sufficiently.
