What to Do If the Volkswagen CC Consumes Excessive Engine Oil?
2 Answers
The solutions for a Volkswagen CC consuming excessive engine oil are: 1. For older vehicles experiencing oil consumption, you can opt to use higher viscosity engine oil to enhance the sealing between the engine pistons and cylinder walls; 2. If signs of oil consumption are detected, regularly check the oil dipstick and replace the engine oil and oil filter as required. Taking the 2021 Volkswagen CC 330TSI Xuanmu Edition as an example: it is a medium-sized 5-door, 5-seat hatchback equipped with a 7-speed dual-clutch transmission, measuring 4865mm in length, 1870mm in width, and 1459mm in height, with a wheelbase of 2841mm and a top speed of 210 km/h.
My old CC has started consuming oil like crazy after 120,000 kilometers, needing a liter top-up every 2,000 km. A check at the repair shop revealed stuck piston rings, which the mechanic said is a common issue with this generation of EA888 engines. The solutions were tough: either spend 8,000 yuan on a non-dismantling oil seal treatment with no guaranteed results, or go for a full engine overhaul with improved piston rings, costing over 20,000. I chose the former, but the problem returned within six months, and now I always keep an oil bottle in the trunk. New owners are advised to use piston ring release agents every 5,000 km, while older cars are better off with a full overhaul for peace of mind. Also, check the exhaust valve immediately if you see blue smoke—a faulty one accelerates oil consumption.
