Not a Tiguan thing, but I switched from Castrol to Motul oil and stopped the oil consumption I was having.
Best Engine oil for Volkswagen Tiguan
Had a 2.0 Diesel Tiguan, same model as you. No oil consimption at all over 80.000 km.
I use the Mobil ESP 0W-20 in my Unitronic stage 1 Tiguan and it\u2019s solid.
It gets regular 10K oil changes with Liqui Moly Top Tec 0w20, and doesn\u2019t burn a drop between oil changes.
140K '19 Tigi 2.0T, switched from Valvoline 5W20 Syn to Mobil 1 0W20 ESP (Dexos D). Changed oil due to oil consumption and secondary air injection DTC. The "latest" member of the Mobil 1 family touts lower emissions (less vapor in the PCV system).
I use an oil extractor on our 2016 Tiguan, my 2016 A4, and 2023 Arteon. All have done a great job and make an oil change an absolute breeze.
Liquimoly Leichtlauf (Hight Tech) exceeds factory standards, and is designed for VW engines. I’ve been running it for years in our Tiguan with a Mann oil filter. It’s a great oil, our 13’ tiggy runs great and is the only oil I would ever run in an old TSI motor.
My Tiguan and Passat all function perfectly with Mobil1 5W40, and I have used this oil for 15 years.
Liqui Moly is just mediocre MADE IN GERMANY oil. Castrol Edge Titanium 0w40 is a good oil, as is Mobil 1 Euro FS 0w40 IMO Redline 0w40 or Amsoil Signature Series 0w40 are better oils.
Using the incorrect oil can cause damage and will definately void your warranty. Call the closest dealership and buy the oil for this oil change.
