According to Consumer Reports, the highly influential advocacy magazine, several cars manufactured between 2010 and 2014 don’t usually require a little oil top off between servicing programming, rather burning through a lot on a monthly basis.
Consumer Reports said the “offending” oil burners were from the Audi, BMW and Subaru brands, noting Audi’s 2.0-liter turbocharged four cylinder and 3.0-liter V6; BMW’s 4.8-liter V8 and 4.4-liter twin-turbo V8; as well as Subaru’s 3.6-liter six-cylinder and 2.0- and 2.5-liter four-cylinder engines – they all ate up much more oil than it was normal, with Subaru being the less serious “offender”. The models that were burning oil abnormally included the Audi A3, A4, A5, A6 and Q5; BMW’s 5, 6, and 7 Series and X5; and the Subaru Outback, Legacy, Forester and Impreza. Naturally, all three brands claimed adding oil from time to time was normal. Meanwhile, Audi is even subject to a class action lawsuit related to excessive engine oil burn.
The magazine said that certain models, such as a BMW 5 Series with V8 engines were 27 times more often required to add more oil between regular service checks than an average vehicle. For decades, oil industry advocates have sought to convince consumers the oil changes should happen at 3,000 miles intervals – but the automakers have been recommending between 7,500 and 10,000 miles. The Consumer Reports info came from a survey of 498,000 owners of 2010 to 2014 models, which concluded that 98% of motorists didn’t have to add oil between specified changes. The other two percent equaled around 1.5 million cars on the roads from said 2010 to 2014 model years.
