What to Do If a Volkswagen Car Burns Engine Oil Severely?

It might be an issue with the oil-gas separator. Here are the reasons why a Volkswagen car burns engine oil severely: Problems with the cylinder and piston rings: Use a cylinder pressure gauge to check the cylinder pressure. If the cylinder pressure is particularly low, it could indicate a problem with that cylinder. Whether the turbocharger has an oil leak: A damaged turbocharger could also cause engine oil burning and reduced power, leading to higher fuel consumption. Another possibility is the valve stem seals and guides. If these parts are damaged, they can cause severe engine oil burning. The exact issue needs to be carefully inspected. A Volkswagen is still a car, and engine oil burning can be fixed.
Hey, I know all about Volkswagen's oil consumption issues. My old Tiguan started burning a liter of oil every 1,000 kilometers after hitting 100,000 km. Don't rush into an overhaul—try these three steps first: First, add a dedicated piston ring release agent to the old oil and drive for about 500 km; sometimes stuck oil rings can loosen up. Second, switch to 0W-40 viscosity oil—it seals better and evaporates less. Third, check the PCV (positive crankcase ventilation) valve carefully—when it fails, it sucks oil mist straight into the cylinders. If these fixes don’t work, you’ll have to open up the engine and replace the valve stem seals. Honestly, prevention is key: change oil and filters every 8,000 km, and running at high RPMs on the highway helps delay carbon buildup.
