I see everyone is affected by the gas hike and I have a question about the grade of gas to use. I use premium right now for my 02 GTI 1.8T and I drive back and forth from south jersey to NYC every week!!! Costing some serious cash, especially with the price hike. Here is my question, Would there any harm to use regular gas in my car? Instead of the premium gas I use now. I haven't switch yet but tempted.
