What to Do About Audi Burning Engine Oil?

Audi burning engine oil solutions: 1. Check if the engine is burning oil internally. Internal burning requires disassembling the engine to inspect whether the cylinder walls have issues like scratches, ovality, or conical surfaces; 2. If the turbocharger is burning oil, it needs to be replaced; 3. Inspect the EGR valve, i.e., whether the crankcase ventilation is damaged. If damaged, it needs to be replaced; 4. Try to use fully synthetic oil or high-quality, high-grade oil. The Audi A6L is a model under FAW-Volkswagen Audi, with dimensions of 5036mm in length, 1874mm in width, and 1466mm in height, and a wheelbase of 3012mm. In terms of power, the Audi A6L uses three engines in total: a low-power version 2.0-liter turbocharged engine, a high-power version 2.0-liter turbocharged engine, and a 3.0-liter turbocharged engine.
Last time my friend's Audi A6 was burning oil, I advised him to immediately check the oil seals and piston rings, as this is a common issue with Audi cars. After driving 70,000 to 80,000 kilometers, the seals age and start leaking oil. It's best not to delay and directly go to a reliable repair shop for an engine overhaul. Replacing the valve seals doesn’t cost too much. For regular maintenance, it’s important to choose the right oil—0W-40 viscosity full synthetic oil is more suitable for German cars. Never opt for cheap, low-quality oil to save money. Remember to check the oil dipstick weekly when the engine is cold, and top up if it’s half a liter low. Always keep a spare bottle of oil in the trunk. Ignoring oil burning for too long can damage the catalytic converter, and replacing that alone could cost several times more than a few bottles of new oil. Nowadays, technicians recommend Audi owners install an oil separator, which can significantly reduce oil burning issues.
