My question is I've seen about 100 engines torn down, both 2.0 and 3.0 3.2 and so on using this oil. Most the customers are going the specified intervals. But these engines look horrid and are having so many issues well even before 50,000 miles. Does anyone have experience with this oil? Are these intervals too long?
Which 2.0TFSI engines? 1st gen? 2nd gen? third gen?
I had VW CC 2010, bought it with 22K in 2012, traded it with 96K in November 2015. Immediately dumped 5W40 Castrol Professional as I think it is substandard oil. Put in Castrol 0W30 GC. On several occasions used M1 0W40 and then when Castrol 0W40 became available in Wal Mart in 5qt jugs, used that oil and still using that oil in my wife's Tiguan (Tiguan bought in 2013 with 34K, now has 60K). CC was driven like it was stolen (of course after engine warms up) and I take Tiguan often to give it "proper" exercise. Never had a single issue with engines, doing 5K OCI's. Tiguan had failed intake manifold 400 miles after I bought it. Flew from San Diego to Charlottesville, VA to pick up car, drove it back to San DIego. In TN got check engine light. I personally think it failed due to that oil and city use or not pushing car hard.
First, as most people know, I am genuine "hater" of that Castrol 5W40, and second, 10K is too long of an OCI due to high sulfur in the U.S> gas. Also, most people in the U.S. use cars to get groceries, go to work. Anything that requires 3+ hours of driving they take Southwest. I think combination of these factors is culprit.
