Synthetic Oils and Premium Gas
im thinking of switching over to synthetic oil. Any one do that before with a mk3. any thing bad happen. is it a good or bad idea to do the switch. i know i need to keep it synthetic once i switch but i wanted to get some opinions before i switched. Another this is would it be a bad idea to run premium unleaded gas in my car. normally i just put the regular in but would it hurt to put the better stuff in?
