Engine oil RAVENOL or OEM Audi
I am using the Ravenol for last 3 changes, oil consumption at 5K change intervals is less than 1/2 quart (about 1/4 qt on last change) and hoping this may lead to less carbon build up.
Pros: less oil consumption
Cons: carbon build up
Vehicle:
Volkswagen Passat
Mileage: 5000 km
