Sinclair Oil's iconic DINO-SAUR has been fueling America since 1916 and is proud to provide innovations such as DINOCARE™ A TOP TIER™ Gasoline that will keep American drivers on the road for years to come.
Little gas station, with bathrooms (make sure to buy something if you just use the bathrooms. Be considerate.), and enough snack options to get you through. Connected to a tiny little restaurant with chicken, pizza and subs.

We have been coming here for many years. We always stop on the way out, non-ethanol for the toys and snacks for the crew. Friendly staff and clean store. What more could you ask for?

Great little store to stop and take a break. Chairs outside in the shade are perfect on a hot day. Good place to watch all the traffic passing on a Sunday afternoon.

The gas prices are sky crazy high. Don't come to Idaho City if you need gas! Gas in Boise before you venture up the mountain..!!
