I just had my first OC at the VW dealer, and the car doesn't run as well as I did with the factory oil.
They wont show me what they put in. And no text on the R.O. just service numbers. The Writer said Castrol Edge. But I couldn't get him to confirm the 508 spec. Engine is now doggy from 1500-2500 where before it spun up like the pistons were on ball bearings.
I'm going in for a recall on rear coil springs replacement in a couple weeks - I'll try to snoop around for bulk oil and chat with the techs.
This place REALLY isolates you from the shop like I've never seen. But I will push to see the before and after of the spring installation.
If I'm in a rush on the interstate, I don't want a spring popping out at 85 MPH.
Maybe they did a computer flash to insure that the car can go that 6 year 72kmiles while under warranty. Reducing the output of the engine by about 30% saves the turbo/oil and engine internals......just a thought.
