Do all Volkswagen 1.4T engines consume engine oil?

[JaxonLynn]

Volkswagen's EA211 1.4T engine does not typically burn engine oil. However, it is normal for some engine oil consumption to occur as long as it remains within the standard consumption limits. Excessive consumption would indicate an oil burning issue. Below is an introduction to engine oil burning: 1. The most important cause of oil burning: Poor quality engine oil. Low-quality oil fails to clean away dust from the air intake during engine operation and carbon deposits formed after combustion. If carbon deposits accumulate in the engine, they can lead to poor lubrication, increased wear, higher fuel consumption, reduced power output, and ultimately oil burning. 2. Factors affecting oil burning: Such as driving conditions, driving habits, maintenance practices, etc. These factors can accelerate oil consumption leading to oil burning, causing the following vehicle issues: Carbon deposits forming in the combustion chamber, causing the piston rings' compression rings to stick and resulting in poor sealing; Sludge forming in the lubrication system, clogging the oil control rings' return holes and weakening their oil-scraping performance; Wear occurring between the pistons and cylinder walls; Corrosion and aging of valve seals leading to sealing failure. Additionally, modern vehicles are equipped with a crankcase ventilation system (PCV valve), and if this malfunctions, it can also increase oil consumption.

I've owned three Volkswagen 1.4T cars, with the oldest being a 2012 Golf. To be honest, not every one burned oil, but many early EA111 engines did have this issue. My Golf VI started showing abnormal oil consumption at 80,000 km - losing about half a liter every 5,000 km. Later I learned it was due to piston ring design flaws, especially the third oil control ring having too small drain holes that easily clogged. The newer EA211 engines have improved significantly - my 2019 Sagitar's dipstick still shows stable oil levels at 50,000 km. Regular maintenance and using the right viscosity oil are crucial. With VWs, you need to check the dipstick frequently, especially before long trips. If you notice blue smoke from the exhaust or rough idling, get the piston ring seals checked immediately.

From a repair perspective, after examining many Volkswagen 1.4T cases, it's clear that oil consumption needs to be evaluated case by case. Turbocharged engines naturally consume more oil than naturally aspirated ones, with up to 0.3 liters per 1,000 kilometers being within normal range. Most actual problems stem from carbon buildup causing piston ring sticking, faulty PCV (positive crankcase ventilation) systems, or aging valve stem seals in older models. Recently serviced a 2015 Lavida where a ruptured PCV valve diaphragm caused abnormal crankcase pressure, sucking oil into the intake manifold. Post-2020 models generally feature improved piston rings and optimized PCV systems, but owners should still use fuel additives every two tanks to clean deposits and avoid overly thin 0W-20 oil.
