What engine oil is used on a 2010 VW CC 2.0T

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. For your CC with the 2.0T engine, it's recommended to use full synthetic oil that meets the VW 502.00 specification. The typical viscosity is 5W-40, though 5W-30 is also often acceptable depending on climate. Using the right oil is crucial for turbocharged engines to maintain performance and longevity, so ensure the oil is VW-approved to protect your engine correctly.
