This place is not open 24 hours nor is any other loop gas station in Novato California. This is the third gas station that I tried that would not help me because I wanted to use cash and even though they had two cashiers sitting there, they said their drawer was put away and they would not allow me to buy gas... Even though I was about to run out. The Chevron on Roland had a sweet gal who was happy to help. Shell gas makes my car ping anyway.
