The fuel pumps at Green Station look standard, but the bamboo fencing used to screen the tanks hint that this diesel is different. Green Station carries only biodiesel made from restaurant fryer oil collected and refined in California. Many of the environmentally-minded customers of Green Station rarely drive and only need to fill-up every few months. Green Station also sells electric vehicles and encourages alternative forms of transportation. Their employees walk the talk, quite literally: two of the three fuel station employees don't own cars.
