What to Do if the Audi A4 Burns Too Much Engine Oil?
2 Answers
Check whether carbon deposits in the cylinders are causing the piston rings to stick. If carbon deposits are present, clean the cylinder carbon deposits first. The probability of the Audi burning engine oil due to damaged valve stem seals is very high. Therefore, after cleaning the carbon deposits, replace the valve stem seals. Check whether the cylinder walls and pistons are severely worn. If the engine oil burning is severe, there is a high probability of severe wear, and an engine overhaul is required.
Severe oil burning in the Audi A4 is quite common, with typical causes including piston ring wear, turbocharger seal failure, or aging valve stem seals. I would first check if the oil level is dropping rapidly by measuring how much needs to be topped up after driving 1,000 kilometers. If the consumption is excessive, it's advisable to visit a professional repair shop for a cylinder compression test to diagnose the issue. The repair usually involves replacing worn components such as piston rings or seals. Meanwhile, using a high-viscosity oil that meets specifications might temporarily alleviate the problem, but a thorough repair is essential for a permanent solution. Ignoring this issue can lead to engine overheating damage, blue smoke from the exhaust pipe polluting the environment, and accelerated aging of other components. Therefore, timely action can prevent greater losses. Regular engine maintenance and using high-quality oil are key preventive measures, especially in Audi models, where this problem is more prevalent in high-mileage vehicles. Consistently monitor the oil level by checking it every time you refuel.
