I asked about a veterans discount and was surprised when the total bill came to $31 for 6 quarts. Thanks Toyota!
I though in Tiguan is Toyota WS equivalent, or low viscosity one?
Aisin sells their own fluid for the 09M/G and it's a T-IV. The interesting thing is if you look online for replacement oil from RockAuto to Walmart just about every type of oil produced in the last couple decades, including the WS is shown as the proper fitment.
The first gen 09M/G take T-IV, which is the equivalent of JWS3309 or VW G055025. The second gen uses WS, which is JWS3324 or VW G055540.
Don't doubt it. Ravenol cross reference VW G055025 indicates T-IV from 2009 through 2018. ECS tuning indicates the VW G055025 through 2018. I think the second gen is 2012 thru 2017. Like I said, it seems likely that the transmission isn't as finicky as some others in the fluid choice. I am not going to worry about it for another 4 years or 40K. I do have to say the bottom fill method VW uses is about stupid. The thing I changed inside thinking it was a filter is basically a baffle. There was almost zero debris on the magnets and the fluid was clean and bright. If I knew all I know now, yesterday, I would have went another 20k or farther mile before doing the change.
