So after my Auto rx treatment rinse phase and running the worst dino pennzoil in my 1.8t passat, I finally switched to the Redline 5W-30. I don't know if it is just my imagination, but man it sure seems like everything is running really smooth! The engine just sounds good. I put a K&N filter in since that was what I thought was a better brand (hope it's ok). I will try and post some numbers when I send in a sample. Thanks for all the help and advice everybody.
