Does the Tiguan L consume engine oil?
2 Answers
Tiguan L does not consume engine oil. The Tiguan L does not exhibit any engine oil consumption issues. This vehicle is equipped with the third-generation EA888 engine, which features technological improvements, including optimized piston rings and cylinder liners. Below is a detailed introduction about engine oil consumption in vehicles: Overview: "Engine oil consumption" refers to the situation where engine oil enters the combustion chamber of the engine and participates in combustion along with the air-fuel mixture. If a vehicle exhibits "engine oil consumption," it can lead to premature failure of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, lack of acceleration power, increased fuel consumption, and excessive exhaust emissions, among other adverse effects. Precautions: Severe engine oil consumption can result in insufficient lubrication of the engine, causing irreparable damage or even complete engine failure. This can significantly increase repair costs and potentially lead to safety hazards.
I've driven my 2018 Tiguan L for 80,000 km and noticed it does consume engine oil, especially when using 0W-20 low-viscosity oil. The main cause is the piston ring design of Volkswagen's EA888 engine, with older models being particularly prone to sticking. I've developed a habit of checking the dipstick every time I refuel and always keep a 1-liter bottle of oil in the trunk. Some oil consumption is normal for turbocharged vehicles, but if you need to top up more than 1 liter per month, it's a cause for concern. Here's a tip: observe the exhaust pipe during cold starts – if you see brief blue smoke, it may indicate aging valve stem seals. I recommend sticking to VW502-certified oils and avoiding cheap off-brand alternatives.
