Does the Bora naturally aspirated engine burn oil?

[MacDavid]

Oil itself has a certain level of consumption. If the consumption is excessive, it indicates an oil burning issue. Oil burning can be caused by the following factors, and addressing these issues can resolve the problem. All engines will experience oil burning to some extent as they wear out over time, which is an objective law. Proper maintenance can delay the onset of oil burning issues. Below is additional information: Factors affecting oil burning: fuel quality, driving conditions, driving habits, maintenance habits, etc. These factors can accelerate oil consumption leading to oil burning, causing the vehicle to exhibit: carbon deposits in the combustion chamber, which can cause the piston rings to stick and result in poor sealing. Sludge formation in the lubrication system, which can clog the oil return holes of the oil control rings and reduce their scraping performance. Wear between the pistons and cylinder walls. Corrosion and aging of valve seals leading to loss of sealing performance. For vehicles with turbochargers, poor sealing of the turbocharger seal rings.

I drive a 2012 Bora, the 1.6L naturally aspirated version. It started burning oil at around 100,000 kilometers after eight years of use, requiring about half a liter of top-up every 5,000 kilometers. The repair shop diagnosed it as aging piston rings and slight leakage from the valve stem seals. The mechanic mentioned that this generation of the EA111 engine has a minor design flaw—the valve cover gasket is prone to oil seepage, and combined with the naturally larger piston ring gaps in German cars, oil burning is somewhat inevitable in older vehicles. However, by keeping an eye on the dipstick regularly and using 5W-40 full synthetic oil during maintenance, it can still hold up for a while. The newer EA211 series has been improved; my friend's new Bora hasn't had any reported oil burning issues.

Naturally aspirated engines burning oil isn't really related to the car model. The Bora has used two generations of naturally aspirated engines, EA111 and EA211. The piston ring sealing in older models was a bit worse, especially after running over 100,000 kilometers, as the valve stem seals harden and oil tends to seep. I've seen several owners who didn't change the oil on time, leading to sludge and carbon deposits clogging the piston rings, which accelerates oil burning. However, the newer EA211 uses low-tension piston rings, and the oil separator has also been improved. Now, it typically consumes less than 0.1 liters per 2,000 kilometers, which is considered normal wear. The key is maintenance—using a fuel system cleaner every 8,000 kilometers to remove carbon deposits can significantly reduce the likelihood of oil burning.

My Bora 1.5L naturally aspirated engine has been running for five years without any oil burning issues. In fact, as long as a naturally aspirated engine is properly maintained, the piston ring sealing is much more stable than that of turbocharged engines. The impression of Volkswagen cars burning oil mainly comes from older turbocharged engines, like the EA888 Gen 2. The Bora's naturally aspirated engine uses a timing chain, which puts less load on the camshaft, resulting in slower oil seal wear. Remember three things for maintenance: use the correct oil viscosity—the manufacturer recommends 5W-40; replace the valve stem seals every 50,000 kilometers; and check the oil level before long trips. Following these steps, you can drive over 100,000 kilometers without major issues, unless you buy a used car that has been poorly maintained.

Having repaired many naturally aspirated Volkswagen cars, 90% of oil burning issues stem from poor maintenance. I once encountered an owner who always used low-quality engine oil, leading to cylinder scoring at just 60,000 kilometers. Naturally aspirated engines are most afraid of sludge clogging the oil return holes—if the piston can't scrape the oil clean, it burns in the cylinder. Replacing the improved piston rings on an old Bora costs about 800 RMB, while changing the valve stem seals costs over 300 RMB. The newer EA211 naturally aspirated engines have mostly resolved this issue from the factory, but be careful not to modify the exhaust pipe recklessly, as insufficient backpressure can actually increase oil consumption. Additionally, coolant must be replaced regularly, as leaking cylinder gaskets can corrode the cylinder walls and accelerate wear.
