BMW Oil Consumption Issues Explained 

BMW Repair in Durham, NC

The Obvious Need for Oil

The fact that your prized European model needs oil is obvious. Every vehicle powered by a traditional internal combustion engine requires motor oil to function properly and survive the rigors of friction. Oil is essential for lubricating the moving internal parts, absorbing some of the heat generated by friction, and suspending dirt so that it can’t cause undue damage. While every auto line requires oil, many enthusiasts are aware that the BMW, though a beloved member of the European vehicle family, is notorious for oil leaks and other consumption concerns. To keep your favorite transportation operating efficiently for a long time to come, entrust it to the reputable team at Carmedix in Durham, North Carolina.

Common Causes and Signs of Oil-Related Issues

Although we’ll need to properly diagnose any problems you’re experiencing with your BMW, we can review some of the common oil-related problems. One of these is a bad PCV valve. If it fails, your car cannot properly separate oil vapors. The oil is then free to enter the intake manifold and burn. As described below, certain BMW models seem to be prone to this concern. Another potential problem is a leaky gasket. Most often this issue is related to the crankshaft seal or the valve cover gasket. When one of these is breached, oil can leak either internally or externally. An additional source of trouble is worn out valve stem seals. Heat and time are their enemies, causing them to harden and lose their damming effect against oil. Once they let the oil by, it can enter the cylinder head. Finally, if your BMW is equipped with a turbocharger, this component can allow oil to leak and burn. This forces your car to use a lot more oil than it otherwise would. Often, preventive maintenance visits provide us with an opportunity to spot developing oil problems in your vehicle. There are, however, some signs you may notice between visits that should prompt you to schedule a visit. Poor engine performance or rough idling, for instance, could indicate a bad PCV valve or leaking oil. These could even cause the engine to overheat. You may also see blue exhaust smoke. This is an almost sure sign that your car is burning oil. Finally, you may get an automated warning. The display may indicate a low oil level or the need for an oil change sooner than expected.

What to Know about Specific Models

BMW is a fabulous auto line, yet they are notorious for oil consumption. Older models exhibit this issue as mileage increases.
