I have a VW and the service guy told me use Lucas Oil Treatment along with Seafoam-half & half!!!!!
Every fill-up I poured the mixture into the gas tank...what that does the Seafoam cleans the injectors and the Lucas Oil Treatment coats the upper piston chamber walls. I drove that VW thang to 250,000 miles where it died on the way into the VW parking LOT!!!!!! I kid you not!!!!!!!! AND I USE SHELL MID-RANGE GAS!!!!!!
