I would drive 5 miles for 2 cents/gallon less.
  1. Robertson & Olympic
    The one that looks like a space station - SE corner. The one on the NW corner costs more
  2. Fairfax & Beverly
    This one used to be cheaper. It was so much less than anywhere else in the area, I was convinced it was a front. New (non-criminal) management?
  3. Van Nuys Blvd & Moorpark
    NW corner, across the street from In'N'Out.
  4. Shell station at Olive and Alameda, Burbank
