Consumer Reports: Cars That Guzzle Oil - NBC 5 Dallas-Fort Worth
Consequently they may consume a certain amount of engine oil and an oil top-up might be required between services. Oil consumption is normal on all engines as it is necessary to properly lubricate the cylinder walls, pistons, piston rings, valves, and turbocharger(s). BMW engines (excluding BMW M) may consume up to 1 quart of engine oil per 750 miles under certain driving conditions. Conversely, due to the increased power on BMW M engines, they may consume up to 2. 5 quarts of engine oil per 1,000 miles under certain driving situations. It is important to note that an engine that is consuming oil that is within the specifications is not indicative of excessive engine wear. However, if a customer experiences a situation where there is in fact excessive engine oil consumption, then our dealer network will be able to provide a prompt diagnosis and solution. 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 Consumer Reports finds that 98 percent of owners of newer cars don’t have to add oil between oil changes. Oil consumption is an inherent feature of all internal combustion engines and the rate of consumption can be affected by such factors as transmission type, driving style, terrain and temperature.
