What to do if the Volkswagen CC burns engine oil severely?

[SanZane]

If an older vehicle is experiencing excessive oil consumption, you may consider using engine oil with higher viscosity to enhance the sealing between the engine pistons and cylinder walls. If signs of oil burning are detected, it is essential to frequently check the oil dipstick and replace the engine oil and oil filter regularly as required.

I've been driving my Volkswagen CC for years, and the severe oil consumption is really a headache. Don't rush into an overhaul just yet—try switching to a thicker oil first to see if it helps. I recommend using a full synthetic 5W-40 oil. Keep an eye on the dipstick levels every time you change the oil, and checking it every 2,000 km is the safest bet. If you always have a spare oil bottle in the trunk, it’s likely due to aging valve stem seals or stuck piston rings. In this case, you’ll need to disassemble the engine and replace the seals with improved ones, which could cost 20,000–30,000 RMB, but it should last five or six years afterward. For regular maintenance, never exceed the mileage interval—change the oil right at 7,500 km and always use genuine OEM filters for the best reliability.
