ARCO in Mill Valley (789 Redwood Hwy)

The cheapest gas station in Marin County! Cash only.

Very basic - debit only - low priced gas

A lot of traffic, but a lot of lanes too

cheapest gas in the 101

Cheapest gas in Marin. I always buy ARCO's gift cards at Safeway, the $50 card is just $50. No extra charge. That makes it very easy at the pump to use this debit card. Employees are helpful, and it is open 24/7. A busy station but lots of pumps and I am in and out fast.

Gas pumps appear to be inaccurate. I filled up my car which has a 12.5 Gal tank, yet the pump charged me for 13+ Gallons.

Cash gets best price. Debit charges are the same as Credit despite lower bank fees.

They always have the best prices, but wish they took credit cards.

Almost always the cheapest station in all of Marin *and* Sonoma counties. Convenient location close to freeway. Usually long lines, but they move pretty quickly.

Almost always a wait for these cheapest-in-area prices. 3 pumps with one-way entrance/exit. Many go inside to pay cash/purchase drinks which slows down line. Very narrow access to middle pump if 1st/3rd taken. Easy access off highway, but line frequently backs up and blocks street.
